"Complex and satisfying. Written from Daniel's point of view, this perceptive first-person narrative is sometimes painful, sometimes amusing, and always rewarding." -- Booklist (starred review)

From the author of Incredible Space Raiders from Space! comes a brand-new coming-of-age story about a boy whose life revolves around hiding his obsessive compulsive disorder--until he gets a mysterious note that changes everything.

Daniel is the back-up punter for the Erie Hills Elephants. Which really means he's the water boy. He spends football practice perfectly arranging water cups--and hoping no one notices. Actually, he spends most of his time hoping no one notices his OCD habits--he calls them Zaps: avoiding writing the number four, for example, or flipping a light switch on and off dozens of times over. But everything changes when a girl at school, who is unkindly nicknamed Psycho Sara, notices him for the first time. She doesn't just notice him: she seems to peer through him.

Then Daniel gets a note: "I need your help," it says, signed, Fellow Star Child--whatever that means. And suddenly Daniel, a total no one at school, is swept up in a mystery that changes everything for him.

With great voice and grand adventure, this book is about feeling different and finding those who understand.
