"Sylvie had an amazing life, but she didn't get to live it very often."From that auspicious opening sentence springs the story of Princess Sylvie, a character in a book that has been gathering dust for years. While waiting for a Reader, the characters while away the time, but when a Reader finally opens the Book they all scramble to take their places and enact the story yet again.
Sylvie, bored and curious, breaks the rules and finds her way out of the Book and into the dreams of a Reader named Claire. Her parents are outraged, but when Claire's brother accidentally sets fire to the Book, it is Sylvie who leads the characters into Claire's mind. There they attempt to reconstruct the story, but freedom from the Book's strictures, as well as the vagaries of Claire's maturing mind, brings unwelcome changes. As Claire ages, their continued survival may depend on the mysterious "girl with the dark blue eyes," who flits through Claire's dreams and waking thoughts and seems to know all about the Book.
