Ten-year-old Peter Fortune has a vivid imagination. He understands just how it would feel to be a cat slinking around on soft paws, purring in the sun. He's experienced the terror and the excitement of being chased by evil dolls bent on vengeance. And he's felt the thrill of using a vanishing cream that can actually make people disappear.

Peter's imagination takes him to extraordinary places. But when it takes him to the place where reality and daydreams meet, has it finally taken him too far?
