Added Upon is the first and most popular novel written by Mormon novelist Nephi Anderson. Originally published in 1898 and significantly enlarged and expanded the 1912 fifth edition, the book was in print until 2005.
The story concerns several spirit children of God who move from the pre-existence, to mortal life, to their eternal reward, interacting with each other at each step.
The novel influenced many subsequent Mormon works of literature, notably Saturday's Warrior.
