Willia is your everyday average teenager. She's 16, a junior in high school, and has had a crush on the same guy for over a year. Just when she thinks things are looking up for her, her childhood bestfriend shows up and everything she's ever believed in turns upside down and she's forced into a world she know's nothing about. While fighting to find the truth and stay alive she must choose between having freedom and being hunted for the rest of her life or to become one of "them" and give up everything she's ever known.
