Plot summary

In trying to save his father Cloud Wolf from the vortex he was trapped in during the Mother Storm, Twig learns that Sanctaphrax is about to be destroyed by the Mother Storm which will replenish the waters of the Edge by returning to Riverise, a legendary garden and waterfall from which all life came. He and the crew of the Edgedancer are then scattered across the Edge by the collapse of the vortex, with no memory of the voyage into open sky. Pieces of the destroyed Edgedancer rain down upon Undertown, killing and injuring many. Among the dead are three important Leaguesmen. A dazed Twig is rescued from the Stone Gardens by the Professor of Darkness and taken to Sanctaphrax where he is made the new Sub-Professor of Light and kept safely away from the other academics.

Meanwhile, Cowlquape, a young boy studying in Sanctaphrax and the son of a wealthy, yet cruel, Leaguesman, hears rumours about the new apprentice and realizes it is the same Captain Twig who had left the city a month before. Cowlquape is at the lowest of the hierarchy in Sanctaphrax, and as such is bullied often by richer upper-class students such as Vox Verlix, an evil, scheming student. Upon learning that his father, the Leaguesman, was among those killed by the sky ship's debris, Cowlquape is confronted by Vox, who says that unless Cowlquape's father can pay his fees he will be kicked out of Sanctaphrax. Miserably, Cowlquape wanders the battlements and saves Twig from jumping off the balcony and killing himself. Twig regains his memory and, in gratitude to Cowlquape, appoints him as his new apprentice. Together they embark across Undertown to find Twig's missing crew.

They travel across Undertown, the Mire (in a ship), the Deepwoods and Riverrise. They find three of the crew in Undertown, one in the Deepwoods, and finally the Stone Pilot, who is the only one who retained her memory of what happened in the Weather Vortex (due to her Stone Pilot's Hood). She tells Twig that his father became a piece of the Great Storm and that Sanctaphrax needs to be released before the Mother Storm itself reaches it so the storm can reach Riverrise so life in the Edge goes on. Twig and Cowlquape fly to the Stone Gardens, and then run to Undertown, where all the academics were evacuated from Sanctaphrax, including the Professor of Darkness, who won't let Twig and Cowlquape release Sanctaphrax. He pushes Twig from the platform and tries everything to stop Cowlquape. He even makes Cowlquape the Supreme Rector, but Cowlquape releases Sanctaphrax, that flies away with the Professor of Darkness.

The two explain everything to the academics and the Undertowners. The Mother Storm reaches Riverrise. In the meanwhile, a giant stone is growing in the Stone Gardens, the academics take the stone and it becomes the new Sanctaphrax, ruled by Cowlquape. Twig gets a new sky ship and the book ends with him leaving to venture towards Riverrise to recover his crew, saying goodbye to Cowlquape, who wishes Twig luck. This is the last book of the Twig Saga.
