Ruby Daly is one of the dangerous ones.
She might have survived the mysterious disease that killed most of America's children, but she and the others sent to brutal government "rehabilitation camps" emerged with something far worse: frightening abilities they cannot control.
But when the truth about Ruby's abilities-the truth she's hidden from everyone, even the authorities-comes out, Ruby barely escapes with her life. On the run, she joins a group of teens who escaped their own camp: Zu, a young girl haunted by her past; Chubs, a standoffish genius; and Liam, their fearless leader, who is falling hard for Ruby.
While they journey to find the one safe haven left for people like them-East River-they must evade their determined pursuers, including an organization that will stop at nothing to use Ruby in their fight against the government. But as they get closer to grasping the things they've dreamed of, Ruby will be faced with an impossible choice-one that could spark a revolution.
