Sherry is eighteen and along with her brother, Danny, they live a pretty normal dull life with hippie parents and typical jobs. Then the moon dissapears and people start to go missing only to reappear later, but different. Sherry has an abusive ex-boyfriend who shows up and claims to be one of these beings that have been showing up around the world. He's no longer the same person in that body. He tells her he has come to protect her and her brother and takes her underground against her will to save her, where they meet others like them. She begins to unravel the truth about him, about what he's really doing here, about the way he looks at her, about the crazy dangerous world they live in.
