The Guardians of Childhood is a series of children's picture books and novels and the inspiration for DreamWorks' Rise of the Guardians adaptation. The books are written and illustrated by author William Joyce, whose other works include George Shrinks, Santa Calls, A Day with Wilbur Robinson, and the much loved Rolie Polie Olie series, which has earned Joyce three Emmy awards.
The series currently consists of five books and will total thirteen by its completion. Originally, it would have been seven chapter books and six picture books, but was recently changed to seven picture books, which will detail each character's origins, and five chapter books.
