Now a major motion picture starring Game of Thrones's Gwendoline Christie, with the lead to be played by Amandla Stenberg, who brought to life the tragic figure of Rue in The Hunger Games. Ruby is sixteen. She is dangerous. And she is alive. For now. A mysterious disease has killed most of America's children. Ruby might have survived, but she and the others have emerged with something far worse than a virus: frightening abilities they cannot control. Pressured by the government, Ruby's parents sent her to Thurmond, a brutal state 'rehabilitation camp', where she has learned to fear and suppress her new power. But what if mastering it is a whole generation's only chance for survival?
