Adam seems to know much more about her than he lets on, and he shares with her a terrifying revelation: the world is ending, and the Committee will decide who lives...and who doesn’t. To help them choose a leader for the upcoming apocalypse, the Committee is holding the Tournament of Freaks, a macabre competition made up of vicious fighters with fantastical abilities. Adam wants Iris to be his champion, and in return he promises her the one thing she wants most: the truth about who she really is. If Iris wants to learn about her shadowy past, she has no choice but to fight. But the further she gets in the grisly tournament, the more she begins to remember—and the more she wonders if the truth is something best left forgotten.
