The 39 Clues consists of two series of adventure books, The Clue Hunt and Cahills vs. Vespers, combining reading, online gaming, and card collecting. Published by Scholastic, the main part of the series consists of eleven books about the adventures of fictional siblings Amy and Dan Cahill trying to thwart the other Cahills to get 39 clues, which will make the finder "the most powerful and influential person(s) on the planet". Amy and Dan agree to the challenge in their grandmother Grace Cahill's will and search for 39 Clues scattered around the world. Continuing books will be about the rising of a new family, the Vespers. Rick Riordan wrote the first book and the main story arc; however, other authors wrote the remainder of the books in the series. All of the eleven books in the first series have been published. The authors are Rick Riordan, Gordon Korman, Peter Lerangis, Jude Watson, Patrick Carman, Jude Watson (again), Peter Lerangis (again), Gordon Korman (again), Linda Sue Park and Margaret Peterson Haddix.[1] Card packs are also being sold which contain 16 different cards that can be used in searching for clues. Each book contains six cards, and the total number of cards is currently 438.[2] Also, the official website offers missions that will lead to clues.
Due to the series' integration of online gaming and card collecting with reading, the series creates an interactive experience. In addition, there are exclusive prizes for children, winnable by buying the books and playing the online game. The novels are designed to incorporate historical elements by placing famous people in the midst of the Cahill family. The background of the game is described, below, using in-universe tone.
The Cahill family has influenced civilization more than any other family in the world. Almost every famous historical figure that has ever lived belongs to it: leaders, scientists, artists and athletes, even if they realise it or not. The Cahill family began five hundred years ago, with Gideon Cahill and his wife Olivia. They had five children: Katherine, Jane, Luke, Thomas, and Madeleine.(Madeleine's and her descendants' existence had not yet been discovered by the other siblings and their branches until Amy and Dan revealed their identity along with the whole story of what happened after the other siblings left the island to follow their dreams. It was discovered by the end of the first series.)[3] These five eventually became the founders of branches: Ekaterina, Janus, Lucian, Tomas, and Madrigal. The secret to the family's power lies in 39 Clues, which are ingredients, such as silk and tungsten, that add up to a mysterious chemical compound that will somehow empower its owner to be the most powerful human being on the planet.
The Cahill family is split into five family branches: the Lucian (Luke Cahill), the Ekaterina (Katherine Cahill), the Janus (Jane Cahill), the Tomas (Thomas Cahill), and the Madrigal branch which was only discovered to be a family branch in Into the Gauntlet (Madeline Cahill). All branches are named as variations of the names of the five children who founded them. The first four branches constantly fight each other for clues, with the Madrigals trying to quell them and distribute power so one branch does not control others. Each of the four main branches has their own unique name (i.e. Lucian), crest (i.e. Two Snakes surrounding the staff), and color (i.e. red).
Founded by Luke Cahill, the Lucian clan comprises the world's greatest leaders and spies, such as Theodore Roosevelt, Winston Churchill, Benjamin Franklin, Isaac Newton, Napoleon Bonaparte, Mohandas Karamchand Gandhi, Ching Shih, Benazir Bhutto, Catherine the Great, Tim Schwieterman, Bernardino Drovetti, Glenn Beck, Bill O'Reilly, Christine O'Donnell, Grand Duchess Anastasia Romanova of Russia, Ninoy Aquino, Marie Louise, Michael Bloomberg, Nicolas Sarkozy, Herman Cain, Silvio Berlusconi, Susan B. Anthony, George Bush, George W. Bush, Gustave Eiffel, Sidney Reilly, and Kim Jong II. The Lucians have produced some of the best leaders including Czar Nicholas II of Russia, King George V of Britain, King Peter I of Serbia, Raymond Poincare, president of France, Linda Sue Park, and Emperor Taisho of Japan. Most important leaders, such as some US Presidents, are members of the Lucian branch, including Lyndon Johnson and Calvin Coolidge. In the novels, Lucians allegedly control secret bases such as Area 51 and Fort Knox, with strongholds in Paris, Delhi, Karachi and Moscow. Lucians have controlled seven countries which are Russia, France, Serbia, Japan, India, Belgium, and the United Kingdom. Lucians Constantine of Russia and Tsar Nicholas I came close to finding all 39 Clues. Characters: Ian, Natalie, and Isabel Kabra (Ian and Natalie's mother), Irina Spasky, and Nataliya Ruslanova Radova (who is a Lucian double agent for the Madrigals) are Lucians. They would do anything for the 39 clues. The Lucian branch is led by Vikram Kabra. When his wife, Isabel Kabra went to join her kids on the clue hunt, he stayed in London. Isabel got charged with murder and is now in jail. Her kids, Ian and Natalie Kabra, plan to take over the branch when Vikram lets them. Symbol: The Lucian symbol is a two-headed snake wrapped around a sword on a red background.

Hershey, John Cadbury, Mitt Romney, Hisashige Tanaka, Jude Watson, Margaret Peterson Haddix, and Marie Curie. They are the branch of ingenuity, despising members of the Tomas branch, due to the fact that Katherine stole one of Thomas's clues when they went to Portugal to escape from their brother Luke. But before they could leave, Thomas married a Portuguese woman. Angry that Thomas had chosen love over duty, Katherine fled Portugal in the middle of the night, taking one of Thomas's clues with her. Thomas vowed revenge when he discovered his sister's treachery. Their branches have been bitter enemies ever since. Ekaterinas are responsible for the Loch Ness Monster, and CERN, using Cairo, the Bermuda Triangle, and CERN as their strongholds. Characters: The Ekaterinas in the novels are Ned, Ted, and Sinead Starling, who are in Book 1 and Book 10, and Alistair Oh, and his uncle, Bae Oh. The current leader of the branch is Frank Starling, after Bae Oh was put in prison for murdering his brother, Gordon Oh. Symbol: The Ekaterina symbol is a dragon with a yellow background.

Symbol: The Janus symbol is a wolf in fighting position with a green background.
The Madrigals were founded by Madeleine Cahill, the fifth child of Olivia Cahill who was born after the other four set out to find the serum, which protected their family from the plague. Olivia raised Madeleine to believe that nothing is more important than family and taught her to keep her brothers and sisters from the Clues; to keep her identity secret she went under the name Maddy Babbit. Grace, Fiske ("the man in black"), Amy, and Dan are both descendants from Madeleine, therefore Madrigals. At the end of Storm Warning, Amy and Dan's au pair, Nellie Gomez, is initiated into the group after helping them, although she is not a Cahill. Madrigals are made up of people who want to prevent any type of war and want to create peace between the Cahill branches. This branch is made up of peacekeepers, such as, Abigail Adams, William Shakespeare, Fredrick Douglas, Desmond Tutu, Mohandas Gandhi, Woodrow Wilson, Malcolm X, Florence Nightingale, Cory Aquino, Linus Pauling, Jimmy Carter, Elie Wiesel, Nelson Mandela, Al Gore, Harry S.Truman, Amelia Earheart, Deng Xiaoping, Mary Pope Osborne, Barbara Park, Ann Bonny, Franklin Delano Roosevelt (Ekat Double Agent), James Preller, Suzanne Collins, Ronald Regan, Angela Lansbury, and Anthony Horowitz. The Madrigals have strongholds on Cahill Island, Grace's house in Madagascar, and Easter Island.
For the past 500 years the Cahills did not know that the Madrigal was actually a fifth branch of the Cahill Family, descended from Madeline Cahill, until recently. The other branches fear the Madrigals because The Madrigals would step in and prevent their success for ultimate power, but the branch has another objective, which is to reunite the Cahill family and stop the warring of the branches. The Madrigals would do anything to prevent the creation of an all-powerful Cahill, often sending double agents to infiltrate other branches in disguise. Symbol" The Madrigal symbol is a C with a black background to represent the hope that they have in reuniting the family. The Madrigal colors, black and white but mostly black, are the colors of the Yin-Yang, the Chinese symbol of balance and peace.
Some say the Cahill formula is the most powerful liquid on the face of the earth. Madrigals have been trying to stop the other branches from gaining too much power because they know that the power of the serum is too great for anyone to hold. The Madrigals already had bits and pieces of the serum formula. They never found the serum formula until Dan and Amy Cahill entered the hunt for clues that took them around the world, Amy and Dan only figured out what the Master Serum was in 'The Swords Thief' when they are in Alistair Oh's secret library. At the end of the tenth book "Into the Gauntlet", Amy and Dan get the serum and decide not to use it because of all the power it contains. They destroy the serum, but the Clues were written down and given to Dan. In Cahill vs. Vespers, it is shown that Dan is collecting the 39 clues to create the Master Serum, no one else knows what he is doing, but the Vespers have suspicions after they notice Dan is buying elements.
Each book in the 39 Clues series includes six cards, which unlock one online clue, the same one Amy and Dan find in the corresponding book. Readers can unlock it by entering the code on one of the cards on their 39 Clues account. If eligible, they will also be automatically entered to win the Book Prizes, the largest being $100,000.
The Maze of Bones is the first book in the series, written by Rick Riordan. It was released on September 9, 2008. The story begins with Grace Cahill laying on her deathbed requesting Mr. McIntyre to change her will to the alternate version and dies soon after it is changed. After he is sure she is truly dead, the Man In Black steps out of the shadows and talks with McIntyre. At their grandmother's funeral, William McIntyre shows them a video of Grace Cahill telling them there are on the brink of their greatest challenge yet. Mr. McIntyre then says they have a choice, one million dollars, or a chance to be the greatest Cahill in history and gives them five minutes to decide. Dan wants the money for baseball cards, while Amy wants the chance in order to make Grace proud. Seven teams are formed to hunt for the Clues: the Kabras, the Holts, Alistair Oh, the Starlings, Irina Spasky, Jonah Wizard, and Amy and Dan.
In the end Amy and Dan chose the chance and receive a sealed envelope that they are instructed not to open. Then the Holts, Alistair, Starlings, and Spasky all accept the challenge. The envelope says: 'Resolution: The fine print to guess, seek out Richard S_______'. Amy then goes to the library but does not find anything there, but Dan opens a passageway into Grace's secret library where Alistair and them find a copy of Poor Richard's Almanack. They give to Alistair to look at, but just then the mansion burns down. They barely escape through the vents (Dan grabbing Grace's cat, Saladin and Amy grabbing a box of jewels on the way out) and go home where they convince Nellie to be their chaperone for their trip. Amy and Dan then head to the Franklin Institute where the Holts set off an explosion, Amy, Dan and Nellie got out alright, but the Starlings weren't so lucky, the Starlings were soon eliminated leaving six teams in the race.
Amy and Dan travel to Paris, France to search for a clue that Benjamin Franklin hid there. While on the journey, Amy and Dan discover that there is more to the Cahill family than they were led to believe. With their information, the Cahills go to the Paris Catacombs. They find some bones which have numbers on them: a magic box number game, planted there by Franklin to give the coordinates to the next Clue. This leads them to a church where they find a room with a mural of the four original Cahills, after who the four Cahill branches are named.
Inside the vase in the room is a small vial, with scrambled words on it. Dan solves the anagram, and they resolve to insert the vial into a lightning rod—one of Franklin's inventions—to charge it. Amy succeeds, but the vial is then stolen by the Kabras. However, Dan still has the original envelope, and solves the puzzle for the clue: iron solute. Amy's Internet searches for Franklin also have led them to the probable location of the second Clue: Vienna, Austria, the home of Wolfgang Amadeus Mozart.
Secret Messages -The strange markings in the pages of the book say "Anne Cahill did not drown".
One False Note is the second book in the series, written by Gordon Korman. It was released on December 2, 2008. After succeeding in obtaining the first clue, Amy and Dan (along with their competition) travel to Vienna, Austria to find a clue relating to Mozart and his sister, Maria Anna "Nannerl" Mozart, famous Cahills(Janus).
Amy, Dan, and their au pair, Nellie, found music by Wolfgang Amadeus Mozart in the end of The Maze of Bones, so they go to Vienna, Austria, to learn about him. On the train, Holts attack them to steal the music, but they fail when Saladin eats the sheet of music from Paris. Dan has great memory and he rewrites the song music on a train napkin. In Vienna, Amy and Dan discover that Mozart had a younger sister: Maria Anna "Nannerl" Mozart. They go to a library and ask for her diary but find out that Jonah Wizard stole it. They steal it from him, then Nellie translates it and notices that three pages are missing.
Then, Amy and Dan discovers that there is another song in the middle of the song by Mozart. That song's name is "The Place Where I Born", so they go to the place where Mozart was born: Salzburg, Austria. There, they see Alistair Oh, and follow him. He goes into the Salzburg Catacombs, and they follow him in. There, Amy and Dan see The Man in Black, and there is an explosion, but they barly escape. Later, Nellie discovers a homing device on the collar of their cat, Saladin. They place it on Alistair Oh's cane when he is sleeping. They also steal a document from him. It is talking about Venice, Italy, so they go there.
In Venice, they follow Jonah Wizard, and find a secret passage in a music store called Disco Volante to a Janus stronghold. There, they find the missing diary pages, and steal them. The pages say that Nannerl Mozart thought her brother was going crazy because he was getting into debt by buying Japanese steel. A name, Fidelio Racco, which was also found on the paper taken from Alistair Oh, appears in the diary. Because of that, Amy and Dan go into Fidelio's Racco's mansion (which is now a museum). There they see the Kabras, who attack them, but Ian falls into the booby trapped key, and is knocked unconscious while Dan throws a tranquilizer dart at Natalie knocking her out.
Then, in the same place, Amy and Dan find the second clue, the clue is tungsten, and two Japanese swords. Because of that, Amy, Dan, and Nellie buy plane tickets to Tokyo, Japan. The book ends with Alistair Oh finding out who is owner of the tracking device that was placed on Saladin, and himself. That person is Grace's lawyer and friend, William McIntyre.

The Sword Thief is the third book in the series, written by Peter Lerangis. It was released on March 3, 2009. The book starts with Dan and Amy in a Venice airport. There, Ian and Natalie Kabra steal their plane tickets and board a plane with their au pair, Nellie Gomez, who is already on the plane. Amy and Dan are then forced to team up with Alistair Oh and fly with him on his private plane to Tokyo, Japan. Together they learn about Toyotomi Hideyoshi, the greatest warrior in the history of Japan, and the son of the first Tomas, also focusing on swords stolen centuries ago by Japanese warrior Toyotomi Hideyoshi. The Holts kidnap Amy, Dan, and Alistair and threaten them into helping them find the next clue.
The group then goes to a train station according to a lead and Dan and Amy nearly get hit by a train. However, Alistair pulls them into the room, saving them both. In this room, they find a haiku, which tells them to use geometry to find Hideyoshi's treasure. Later, they find some geometric shapes, but are chased by the Yakuza and are once again nearly killed. They are rescued by Nellie, who has struck a deal with, and is accompanied by, the Kabras. Ian gives Amy a small coin of importance to the search, after their hands brushed up against each other in the car, hoping that this token can gain Amy's trust.
They decode another message in the shapes, and some English letters. The message tells them to go to Korea. In Korea, everyone goes to Alistair's house. There, Alistair announces that he is tired so he'll take a nap, then they all can search for the clue, Ian asks Amy if she wants to go in the maze with him, she refuses him since Alisair said no one should go wondering on the grounds, after a while, Ian comes out the maze screaming since Alistairs dog has bitten him on the bum, and ripped his trousers, he blushes infront of Amy, but quickly changes his attitude back infront of everyone else, since the screaming woke Alisair up, he gives them a clue to enter his secret library 'Why leave the factory when the workers are in their prime?', the Kabras automatically give up as they have no idea what time people work at, Amy is sure she has an idea, she figures out that 'why' sounds like 'y', when 'y' leave the factory, you get 'factor', then she notices the word 'prime', meaing 'prime factors', Dan quickly solves the puzzle, '5, 7, 11, 13', when timezed together, they get 5005. They are then welcomed into the Oh sanctuary. There, they look up books about the Cahill family in Alistair's secret library, this fascinated Amy and Dan since they've never been told before about their family, while the Kabras find it rather boring since they've known everything since they've been a child.
By reading one of them, Amy and Dan figure out that the secret of the 39 Clues is the secret to alchemy (philosopher's stone), also in one of the books they learn they have to go to a mountain called Pukhansan. While trying to find the mountain Ian offers a race between himself and Amy to a near-by boulder, to show she is strong, she accepts and beats Ian by a second, there they both stand on top of the boulder out of breath, Amy looks into Ians eyes seeing him from a different point of view, her example is changing the angle of a painting and finally understanding the meaning, she feels embaressed and thinks Ian is laughing at her, but realises that his eyes are inviting her to laugh with him, her heart is racing as their faces are only inches apart, they soon get interrupted by Dan who calls them 'Mr and Mrs Kabra', causing Amy to blush. While on the boulder Amy spots the mountain and they all start to head to it, they find an entrance, and open it with the coin they have, it causes the cave to rumble and a boulder to nearly hit Amy, but Ian runs over to save her and lands on top of her, he places his hands to lock with hers and re-adjusts himself so his lips are brushing up against Amy's, the dust clears and everyone gets up, Ian realises that instead of thinking about himself first, he thought about saving Amy first, which shocks and confuses him.
Inside, they find all of Hideyoshi's treasure, and the third clue, gold. The Kabras have a plan, but little do they know that Dan also has a plan. He discovers an anagram and says the next location is Lake Tash which he claims is located in Kyrgyzstan. The Kabras then betray them and seal them inside the cave, burying them alive. Dan begins to tell Alistair and Amy that he tricked the Kabras into going to a non-existent Lake Tash, but is interrupted by Amy. She realises that they are surrounded by charcoal and gunpowder. Using the matches Dan took from the Thank You Very Much Hotel, they blow up the cave. Dan and Amy make it out, but Alistair appears to be crushed under falling rocks, and is presumed dead. The cops arrive and Dan and Amy tell them about Alistair. They then see Bae Oh talking to The Man in Black.
Dan and Amy find Nellie and Saladin in the parking lot of the park. On the way back to Alistair's house, Amy tells Nellie what happened. When they get back, Dan tells Amy that the actual word is Alkahest, not Lake Tash, which is the word for the philosopher's stone. Amy then figures out that it isn't Alkahest, but instead, Al Sakhet. 'Al' means 'of' and 'Sakhet' was an Egyptian goddess. They learn that their next location is Egypt. Nellie suggests that Dan and Amy both go take a shower. Dan walks into Alistair's bedroom, and finds a pair of filthy white gloves on the bed. He realizes that Alistair is alive. At first he is extremely happy, but realizes that he ditched them again. The book ends with Bae Oh, sitting in his office. He pages his secretary, but Alistair answers instead. Alistair threatens his uncle, and when Bae looks in his receiving room, no one is there.

They eventually realize that the hotel is an Ekat stronghold and find three Sakhet statues with 2 of them having a computer representation of a drawing of a tomb inside of each which Dan memorizes. They then find out that the hotel belongs to Bae Oh, the head of the Ekats, who traps them in a cage of unbreakable plastic.
A little while later Nellie comes to save them by deactivating the cage with Saladin's help. Then while escaping the hotel they get into a car of a person called Hilary Vale, who turns out to be one of Grace's many best friends. They then receive a letter from Grace and a Sakhet statue identical to the one without the drawing. They then open the statue and take out a papyrus. On one side there is a poem from Katherine Cahill.
On the other they see one last different tomb from the other two identical tombs. Dan then draws the other two from memory, puts the sheets of paper together and sees the correct tomb which turns out to be the tomb of Nefertari. Then Theo, Hilary's grandson takes them there even though its under renovation because he's a tour guide. In the tomb they get lost and nearly killed by Irina but they manage to get out but are trapped on an island crowded with aligators by Jonah which they eventually escape. The next day they found out that Hilary and Theo were against them and use them as a lure to send Irina elsewhere.

The Tomas stronghold then come to attack Amy and Dan, they get rescued by another Tomas, who doesn't acre about the Clue Hunt, he then meets with his choir, which Kurt is apart of, Kurt takes Amys hand and everyone runs through the forrest, the Tomas catch up, but Dan tells the choir to sing in a circle, this causes the Tomas to cme around them at all angles, they suddenly all fall into a hole that wasn't activated by everyone else since they were too light for it.
While leaving South Africa, Dan and Amy were captured by the Kabras. They were about to kill Dan when suddenly a professor, (who helped them at the Tomas Stronghold), saves them again. They escape together with what Dan thought was the vial of green liquid that they thought was their lead to the second clue in the Maze of Bones. They escape by flying Grace Cahill's old plane (The Flying Lemur). During the ride, Dan and Amy have a little quarrel, accidentally breaking the vial and spilling some of the contents onto Dan's arm. It turns out to be a Kabra poison. To get the antidote to save Dan, they fly to Grace Cahill's home in Madagascar.
While at Grace's Madagascar home, where they learn the clue is aloe, they find a page in her journal that says, ″I am feeling melancholy today, thinking about my dear A & H and missing them so. I cannot even bear to listen to my beloved di Lasso, because of the reminder...″, and on another page it says, ″I have written Deng Xiaoping, who has agreed to grant to visit to A & H when he discovered that they, like him, are M.". They try to figure what 'M' means, they wonder what the song has to with the Arthur and Hope, and discover that on the song it says 'Madrigal', which is also a type of song, they then realise, that their parents were Madrigals.
Secret Message -In the front and back of the book there are a series of letter written on the spears by arranging like this G A E M D I A L A E R C = A R G L E D R -It says "Grace= Madrigal Leader." -The morse code on pages 39–65 reads: THERE IS A MADRIGAL WATCHER
The Emperor's Code is the eighth book in the series, written by Gordon Korman. It was released on April 6, 2010.[1][5] Amy and Dan go to China to find the next clue and "coincedentally" they are the only ones on the airplane who are watching a movie about the forbidden city instead of The Terminator. Unfortunately, they are not the first ones there, and meet Alistair Oh at the Beijing airport. He tells them that the Kabras and Holts are already in China after they refuses his offer at alliance. After coming from the airport they go to the Forbidden City in Beijing and discover that Emperor Puyi was a Janus. Dan finds a piece of silk fabric in an attic in the forbidden city, which holds a poem as well as the Cahill crest and the branch crests in a mathematical way: Lucian + Janus + Tomas + Ekaterina = Cahill, the poem says "That which you seek, you hold in your hand, Fixed forever in birth, Where the Earth meets the sky".
Amy then starts doubting their parents because they are Madrigals and she tells Dan that maybe they should be glad their parents are dead, which upsets Dan who runs away, getting kidnapped by Ian and Natalie Kabra. The Kabras put Dan in Jonah Wizard's lollipop factory after searching him and finding nothing. Jonah finds Dan and takes him around China. Amy and Nellie go to Jonah's concert, hoping for information on Dan's whereabouts. Jonah lies to them, saying he hasn't seen Dan. The next day, they read in the papers that Dan is indeed with Jonah.
As Dan and Jonah go to the Shaolin Temple, Dan learns Wushu and accidentally finds the remains of a burnt lab. Dan also finds a locket which holds a picture of a woman, who looks exactly like his mother but with clothes from a different time, which he keeps. Jonah's dad receives a message on his phone which the monk interprets correctly as the location of a terracotta warrior. Jonah calls Dan to go to the terracotta warriors museum. There they find a trap set by the Kabras. onah was going to leave but he came back for Dan at the last second, and Dan uses what he learned from Wushu to defeat the man. After return to the hotel room they meet Jonah's mother, Cora Wizard, claims Dan to be a Janus. Dan gets mad at the Wizard family after realizing that Cora was involved the night their parents die and leaves, screaming that he is a Madrigal.
Through television, Dan sees the Holts climbing Mount Everest. He thinks that the next destination might be there. Amy knows the next destination when she changed Puyi's room in the Great Wall following the feng shui requirements to achieve positive qi. She sees an image of Mount Everest projected on a wall. The Cahill siblings meet in front of the A-Star, a helicopter. After speaking with someone on Nellie's phone (she claims it's her uncle), the reluctant pilot flies both of them up Mount Everest and where they find a Janus vial left by British Cahill mountaineer, George Mallory, where they realise his famous quote 'Because it's there', did not mean everest, but the Clue. Eisenhower Holt and Ian Kabra catch up and they fight over the serum. Ian accidentally falls, Amy has a choice between saving the serum, or Ian, she chooses Ian as it is the right thing to do, but i disgusted with herself that she ever thought of thinking of saving the serum over a human being, this choice causes the Janus serum to break.
When Dan thought that they've lost the clue, Amy shows him the poem on the silk and tells him the next clue is raw silkworm secretion. They also realize that the formula on the silk means that all the serum of the branches add up to one master serum. Then Dan shows Amy the locket he found at the Shaolin temple and they see a name of a woman pirate named Anne Bonny. The next destination is the Caribbean.
Secret Message -BECAUSE IT'S THERE - On the crown -GM - Base of the right side of the helmet, near the ear, it stands for George Mallory who said the quote right above this sentence. -Henry - Somewhere in the left part of the background, beneath the left ear. Henry is the name that Emperor Puyi changed his name to after he moved out of the Forbidden Palace. -The encircled words in the book say "Madrigals are behind everything. They lay out the path the others will walk. The end is coming."
Book 9 Storm Warning by Linda Sue Park. It was released on May 25, 2010. Amy and Dan Cahill arrived at an airport and argued about where to go next, Jamaica or Bahamas. Dan convinces Amy to go to Bahamas, largely because he wants to go to a amusement park there. Dan tells Amy that he got a message from Hamilton saying that his dad knows where they are going next, which made them suspect Nellie immediately. Hamilton also says that for some reason (later revealed to be Anne Bonny) they are going to South Carolina instead. On the plane ride they corner Nellie and she admits that she works for William McIntyre, hurting Amy greatly and causing them to lose complete trust of Nellie.
They arrive at the Bahamas. They take a boat tour out in the ocean, when Amy invents the color Azturpealean(a combination of azure, turquoise, peacock, and cerulean). Dan and Amy receive a coded note from a stranger, which they unscramble, leading to the discovery of a cave, with the Tomas symbol, at the east end of the island. Dan retrieves a bear claw from the cave. When the tides rise Amy and Dan almost drown and Amy hits her head, which meant they had to go back to the hotel early. The three head to Kingston, Jamaica. In Jamaica, a woman named Miss Alice, also a friend of Grace's, has something to say to Nellie, Nellie finds out that her snake nose ring is actually a lock puzzle piece, but also that Grace hired Nellie especially for the Clue Hunt. Miss Alice also gives them a clue which send the three to a monument and find a strip with the words EKTOMALUJA.
After reading a list of items on the boat Anne Bonney was on, they notice that one of the objects was a jade dragon necklace, Amy's necklace. They then plan to steal a charm on Isabel Kabra's bracelet, believing it is vital for the Clue Hunt, they manage to knock Isabel out and steal the Wolf Charm. After that, they head out to the Port Royal excavation site with Lester (Miss Alice's grandson), then, they find a box (which was donated by Grace)that can fit all the things they have collected, dragon necklace (Ekat), Snake nose-ring (Lucian), Wolf Fang (Janus), Bear Claw (Tomas).
Isabel spots them and sends two hired thugs after them. The two men chase Lester and fall with him in a quicksand in the ocean. Lester saves the men but ends up dying. Lester's death has a profound effect on Amy and Dan, causing the siblings to decide that it would be better for everyone if they quit the hunt for the 39 clues and return to their Aunt Beatrice. However, instead of driving them to the airport, Nellie stops at Moore town, and gives the box to the Man In Black angering Dan and Amy. The Man In Black makes an agreement with Amy and Dan that allows the siblings one hour to open the box, he walks away saying in this game all sides are one and you'll need all of us to survive. After many tries, they figure out that on the strip they found that the MA in Tomas is really for Madrigal, the last branch, and the mobius strip was the all side are one hint because a mobius strip has only one side. Amy inserted the strip to the final slit and the box sprung open. It contained a poem by Madeleine Cahill and the clue, Mace.
The Man In Black reveals his true identity as Fiske Cahill, Amy and Dan's Great-Uncle and Grace's younger brother and tells them about Madeleine Cahill and the Madrigal branch, as well as granting the two active Madrigal status. He then also gives Nellie active Madrigal status even though she isn't a Cahill by blood. After reading the poem, Dan concludes the siblings' next stop is England. There, they must finish the clue hunt and stop the other branches from fighting, as per their new status as active Madrigals.

It was written by Rick Riordan, Peter Lerangis, Gordon Korman, and Jude Watson.

The children agree to take the serum and they'll leave in the morning. At night, Gideon goes to get his life's work, and possibly a updated version on the serum, but is interrupted by Luke from which Gideon had noticed had already taken his part of the serum, Luke tells Gideon that Damien and his men are approaching, Gideon tells him to run, as he does so. Damien walks in, and after an argument between the two, the lab sets on fire, killing Gideon, and possibly Damien. On the boat, the four children and wife see the explosion, Olivia starts to cry, and Luke goes ahead knowing that Gideon has died, after a lot of fighting the four children take separate ways, with Luke going on way, then Jane, then Thomas and Katherine going together. This leaves Olivia alone, with no one knowing she is pregnant with a 5th child.

She had to steal it back from George S. Patton. It is mentioned in the story General Patton was a Vesper and he chose to battle at Casablanca for Gideon's Ring. The last story returns to present day with Dan and Amy. Fiske, Amy and Dan travel to Switzerland together to retrieve the ring of Gideon Cahill. They find the ring in Grace Cahill's chalet, but there were two Vespers trying to rob it from her. Their names are Casper Wyoming and Bruno.

This book was written by Gordon Korman and was released on August 30, 2011.
The book begins seven Cahills (Nellie Gomez, Alistair Oh, Ted Starling, Natalie Kabra, Phoenix Wizard, Fiske Cahill, and Reagan Holt) get kidnapped by the Vespers all around the globe. The Vespers also attempt to kidnap Dan and Amy after sending a team to apprehend them on the way to school but are defeated by Amy and Dan. After the incident, they are taken back to the mansion, where William McIntyre reveals that seven Cahill members have been kidnapped by Vespers at the same time all around the globe. Suddenly, a helicopter drops off a phone with a text-message from Vesper One telling them to go to Florence, Italy, tomorrow, or of the prisoners will die. Amy then immediately goes to the attic (now a command center with a satellite called 'Gideon') to call all the Cahill members around the world, where she reveals that they will both follow Vesper One's orders and try and rescue the hostages. Sinead, McIntyre and Ian remain in the Command Center in order to find more information about the Vespers and the possible whereabouts of the Cahill hostages, while Dan and Amy go to Florence Italy.
When they arrive in Florence they get another message instructing them to steal the Caravaggio's famous "Medusa" located in the Uffizi Gallery. They later meet up with Jonah and Hamilton to help with the mission. After stealing the painting they then get another text telling Amy and Dan where to drop it off. The Vespers find the painting to be a fake and Amy and Dan get sent a video of Nellie being shot in the shoulder. Vesper One then told them they had 96 hours to find the real painting or Nellie's condition would get worse... Amy, Hamilton and Jonah started searching the library for possible clues about the location of the real shield. While the others are searching for information, Dan has been secretly been collecting ingredients to create the Master Serum. Back in the library, Amy, with Hamilton's help, discovered that the picture was stolen by a Mud Angel named Gregor Tobin, one of the saviors of Florence's art during a great flood decades ago. They then arrive in Lake Como, where he lived and tried to offer him the golden Sakhet statue from Grace in exchange for The Medusa, but failed. After they searched the house, they found the painting hidden in a secret gallery and stole it. Also, during the escape, they, Hamilton and Jonah crashed their speedboat near the lake and Amy lost the DeOssie's charger. She called Sinead and Ian and asked them to find a charger.
Ian then went around the town, searching for charger with a picture of the phone itself but almost failed, until he bumped into a very worried Evan Tolliver (who earlier got arrested for intruding at the Cahills' house), Ian then tells Evan that since Amy has been ignoring his calls, that maybe she's dropping a hint, Ian possibly says this out of jealousy (as he could still have feelings for Amy). Evan immediately recognized the phone, therefore Ian decided to tell Evan about the Cahills and invited him to join the Command Center and help track Vesper One, who they believed had a connection with the DeOssie factory. After that, Amy and Dan found very strange Latin words on the back of the Medusa and Dan decided to ask his friend Atticus Rosenbloom (who he met over the Internet) for help, since he's extremely smart and can speak 10 languages. Atticus, who really likes Dan and feels connected to him because of his mother, called them and told them the strange words - Por San Aria where Porta Sanavivaria, the Latin name for the Gate of Life, located in the Colosseum in Rome. After they arrived in Rome, they are joined by Atticus and his very strange yet attractive older half-brother Jake Rosenbloom. In the Colosseum, Dan found a map of the tunnels, which resembled the snakes in Caravaggio's 'Medusa,' which was a map, leading to an unknown direction. In the tunnels, they found Leonardo da Vinci's Medusa shield, which Caravaggio based his painting on, and a book by Marco Polo called 'Il Milione' (The Million), which they believed the Vespers were looking for. After an intense argument with the Rosenblooms, the sibling stole Marco Polo's book and left the Colosseum, but the police recognised them from the Uffizi theft and turned the into one of Interpol's most wanted.
Meanwhile, Jonah, Hamilton, Ian, Sinead, McIntyre and Evan all found the DeOssie factory and got in very easily. They searched it because they thought the hostages were hidden somewhere in the factory but the only thing they found were chargers for the Vesper phone. After Hammilton accidentally activated the trap, the entire DeOssie factory explodes. The four Cahills escaped but Ian found a paper with the Lucian crest on it. Phoenix Wizard performed an operation on Nellie's shouder but was unable to get the bullet out, so Natalie interfered and finally got the bullet out, saving Nellie's life. Vesper One was impressed by Amy and Dan and sent them the directions for the next drop-off - a circus. After they arrived at the circus, the picture was stolen by a female acrobat. The lights went off for a few seconds and caused panic among the people in the circus. Right before they escaped, Amy and Dan saw the dying girl who stole the Medusa, shot in the neck. They asked her who hurt her but the only thing she told them was "bruciato" - burn. In other words, Vesper One has a burn on his arm. Then, when they thought everything had ended and the Vespers were finally going to release the hostages, Vesper One sent them a picture of the 7 hostages and ordered them to go to Lucerne, Switzerland immediately. They were about to hail a taxi but stopped when the Vesper phone rang and received the message from Vesper One, who was in the taxi they were going to hail.
Secret Messages: -On the front cover, the code says "Guardians". -On the inside front cover, the code is "Damien is alive". -In the pages, the code is "The mother was murdered".
This book was written by Jude Watson and was released on December 6, 2011.
In the beginning of the book, Amy and Dan are wandering in Santa Maria Novella train station in Florence when they come across a girl named Vanessa Mallory, who is actually Cheyenne Wyoming in disguise and use her as a distraction in order to get into the train for Lucerne, Switzerland where Vesper One is sending them for their next mission: find the de Virga map. Once they're on the train, they realized that they were tricked, and an Interpol agent named Milos Vanek, tried to hunt them down. But, they manage to escape the train by hiding inside other people's luggage bags, into Enderberg. Their first shot to find the map is the auction house in Lucerne, and they have to be disguised as rich people to succeed. Inside the house, they sneak in to the office and get the de Virga Map archives written in German. Ian translates it, revealing that these 4 people, Otto Hummer the professor, Jane Sperling the socialite, Marcel Maubert the art dealer, and Reginald Tawnley the person who owned a private library, have something to do with the map. Unfortunately, the report about Amy and Dan's criminal heists have reached the auction house, and they have to sneak out by creating diversions.
Moments later, they've been approached by William, receive a GPS wrist watch, and dropped off at Basel. Sinead and Evan from the Cahill Command Center share the information they have gathered of the four listed people. Maubert and Tawnley died in war, Hummel worked in the Nazi party, and Jane is a Jew who is thought to have tried to protect the de Virga map, which was owned by a Jewish family.
Meanwhile, Dan is making progress of gathering ingredients to create the master serum, which seems to be a backup if anything goes not according to plan. Amy has pieced all the informations she and the center gathered, and concludes that they have to search the Janus stronghold who kept the clue Pearl, Neuschwanstein Castle.
Jonah and Hamilton are called to back up Amy and Dan. But at Munich, Germany, on the way to the castle, they are tricked by Cheyenne Wyoming disguised using the name Nicole; Jonah and Hamilton both are almost killed.
Back in the castle, inside a room in the tunnels, Amy and Dan find a black notebook owned by Sparrow, a.k.a. Jane Sperling. Inside is a note that probably will lead them to the location of the de Virga map. By another stroke of bad luck, Casper bumps into them, and almost kills them, when Jonah and Hamilton come to the rescue. The siblings think this is strange: why do Casper and Cheyenne, who are Vespers, try to kill them?
Analysis comes from the command center about the notes: they are about a Johannes Kepler book that was recovered from the castle to the Library of Philosophy and Cosmology in Prague, Czeh Republic. They head there to investigate the book, but can't without a reference paper. They try to use Rosenbloom's father, but it's still not a success. At the hotel, they again escape from Milos Vanek.
Another task from the command center is received, telling them about the jacket label. The manufacturer is located in Kutna Hora - possibly the prisoners' holding place. They go to Sedlec just for observation.
Meanwhile, Atticus wonders how Dan is doing, and remembers his memories from his mother Astrid, about a group called the Guardians and a ring.
Later on, before they board a plane, Jonah and Hamilton are approached by Luna Amato, Milos's partner. She seems very cynical, and Jonah has a bad feeling about her.
In Sedlec Ossuary, they discover where the sender of the message is coming from, and get a flash drive file about a V-1 report. This makes Dan shocked, because he sees AJT, the siblings' father's initials. Now they know Arthur is a Vesper.
Back at the hotel, Erasmus comes to them and answers their questions about Arthur. Plus, Amy got a great news from Ian: a UK professor, a Lucian, agrees to help Amy and Dan to enter the library. This is a great effort.
Outside the library, they bump into Atticus and Jake again. Amy doesn't like Jake because he turned them in to the Interpol before. Atticus sees the picture of Jane Sperling, and confesses she is his great grandmother. Atticus and Jake both decide to help the siblings. Inside, Katja Mavel, the director of the library, gives them what they want. Jake succeed in luring her away, and that leaves Dan, Amy, and Atticus. They finally find the map inside the book itself.
Later, the Cahill siblings are trapped inside the room (Atticus managed to get out), and a fire occurs. It's the Wyomings, trying to kill them again. With Dan's and Evan's hacking skills combined, the siblings make it out alive.
Meanwhile, in Rome, William is killed by the waiter.
Back in Prague, Amy and Dan reveal their true intention about what they're doing, and Atticus reveals his involvement as a Guardian. The siblings had never heard of the group before. Dan manages to make a connection with Il Milione and the map: it's Samarkand, Uzbekistan - possibly the next stop for the next heist. V-1 asks them to drop off the package at the Astronomical Tower, near the statue of Jan Hus. They do what has been asked, but it goes wrong. Atticus comes and is kidnapped.
V-1 now knows Dan and Amy have been hiding Marco Polo's epilogue all this time, and explains that Atticus was the price of keeping it from him. Minutes later, another message goes to Dan's phone, sent from AJT.
He knows now that his father is alive... Cover Messages -On the bottom left space of the statue you can see the words, "Find Stan", possibly pointing to Uzbekistan or a person named Stan. -Near the bottom of the statue you can see an outline of the country Uzbekistan. -Instead of the Nazi Swastika, there is a V for Vespers underneath the eagle. -There are constellations on the front, possibly relating to the indication that they have to steal a star map. -On the website it reveals that there is a puzzle on the eagle. -The eagle on the inside Cover says "I will move the Earth". This could be the reference to Archimedes, his quote was "give me somewhere to stand, and I will move the earth" referring to how Archimedes designed block-and-tackle pulley systems, allowing sailors to use the principle of leverage to lift objects that would otherwise have been too heavy to move.
This book will be written by Peter Lerangis and is to be released March 6, 2012.
The Vespers have Atticus, Dan's friend, and are planning to kill him if they don't get what they want.
The Cahills aren't the only family searching for the Clues. Amy and Dan have managed to rescue one of the Cahills kidnapped by the Vespers, but the remaining hostages are still in peril. The Vespers are far more dangerous than the siblings ever imagined, even worse, it looks like they have an undercover mole posing as a Cahill.
The Vespers have crossed a line. Amy and Dan were devastated when the Vespers kidnapped seven Cahills around the world, holding them hostage until Amy and Dan delivered an impossible ransom. But at least the hostages were Cahills - members of the world's most powerful family, trained to face all odds.
Now the Vespers have gone too far. They've kidnapped Atticus, an innocent 11-year-old boy and Dan's only friend. Now Dan and Amy are in the struggle of their lives. Because if they can't outwit the Vespers, Atticus will be killed.
