The book is ancient, ravaged and full of utter nonsense. But the moment it enters Daphna and Dexter's lives, bizarre things begin to happen. Why is their father, who found the book, suddenly so distant? Is the old man who took it from him some kind of hypnotist? Why is a giant, red-eyed boy menancing them? And what does their thirteenth birthday have to do with all this? Daphna and Dexter can't stand each other, but they'll have to work together to learn the truth about the Book of Nonsense - before their lives come apart completely.
