About this book

Jason has a problem. He doesn't remember anything before waking up on a school bus holding hands with a girl. Apparently she's his girlfriend Piper, his best friend is a kid named Leo, and they're all students in the Wilderness School, a boarding school for "bad kids." What he did to end up here, Jason has no idea-except that everything seems very wrong. Piper has a secret. Her father has been missing for three days, and her vivid nightmares reveal that he's in terrible danger.
