Picking up where the cliffhanger ending of book seven left off, this book follows Sabrina, Daphne, and Puck through the world of the Book of Everafter, where all the fairy tales are stored and enchanted characters can change their destinies. The girls (and Puck) must chase the Master through a series of stories, where they're willing to change what they need in order to save their baby brother. Soon, however, they are confronted by The Editor -- the book's guardian -- who, along with an army of tiny monsters known as Revisers, threatens the children with dire consequences if they don't stick to the stories. So they move from one legendary tale to the next doing their best to find the Master and stop his plan to steal and inhabit the child's body. Along the way they'll meet Alice, Mowgli, Jack the Giant Killer, Hansel and Gretel, and the Headless Horseman. But will they find their brother in time?
