When he was 13, Zack Hawthorne went missing; disappeared into thin air. Three years later he surfaces, emerging from the woods covered in blood, scars and bruises. Nobody knows where he went, what happened to him or why he was gone so long. His family is confused; their son is not who he was before. The twinkle is gone from his blue eyes, his smile has vanished and he refuses to say a word. What happened to Zack and how did he get back?

Or is it even him?
