Warriors Kaleb and Aya will stop at nothing to destroy their competition. But when Kaleb, a prizefighter from the otherworldly Untamed City, finds his fate entwined with that of Mallory, a seventeen-year-old human girl, he can't seem to separate the vicious Carnival contest he's entered from his sudden—and obsessive—devotion to her. All Mallory knows is that she's being pulled toward Kaleb and his foreign world with an emotion so fierce that it's utterly foreign. The two are forced apart, but when the City's ruler raises the stakes of the Carnival's prize, there's nothing Mallory, Kaleb, or Aya can do to stop the two worlds from colliding. Mallory's about to discover her true identity—and stumble into a fate she'd die to avoid.
