Half the population of the island of Madera are dead, killed by an unforgiving and indiscriminate plague. Oriana dreams of escaping her life of ruthless cruelty from the people who now rule over those who remain. No telling whom the plague will strike next, Oriana means to find freedom for herself and her people. Drawing strength from ancient tales of her enemy, young Oriana transforms herself from victim to warrior with the help of a mysterious and powerful dagger given to her by a kind and dying boy. Years later, during her enemy's betrothal ritual, Ezra, a boy she has never before seen, selects her as his mate. With servitude her only option, Oriana accepts the offer. Whisked away to a seemingly perfect world, Oriana discovers sinister secrets at every turn, including the identity of Tristan, a boy with whom she shares an undeniable but impossible connection. Why would a boy she doesn't know wish her to be his betrothed? Why does she feel such a strong pull toward a stranger? Someone in Ezra's family not only knows the answer to both those questions, but also about the dagger Oriana possesses. He will do anything to stop the union. Now, with everything on the line, Oriana turns inward to find the strength she needs to seize the full power of the dagger so that she may protect herself and save her people.
