The Darkest Minds – Alexandra Bracken

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?
