Chloe King is a normal girl. She goes to class (most of the time), fights with her mom, and crushes on a boy - or two. But around her sixteenth birthday, Chloe finds that perhaps she isn't so normal after all. There's the heightened night vision, the super fast reflexes and claws. As she discovers who she is - and where she comes from - it is clear she is not alone. And someone is trying to get her.
