From the best-selling author of The Darkest Minds comes a sweepingly ambitious, high-octane tale of power, destiny, love, and redemption. Every seven years, the Agon begins. As punishment for a past rebellion, nine Greek gods are forced to walk the earth as mortals. They are hunted by the descendants of ancient bloodlines, all eager to kill a god and seize their divine power and immortality. Long ago, Lore Perseous fled that brutal world, turning her back on the hunt's promises of eternal glory after her family was murdered by a rival line. For years she's pushed away any thought of revenge against the man-now a god-responsible for their deaths. Yet as the next hunt dawns over New York City, two participants seek her out: Castor, a childhood friend Lore believed to be dead, and Athena, one of the last of the original gods, now gravely wounded. The goddess offers an alliance against their mutual enemy and a way to leave the Agon behind forever. But Lore's decision to rejoin the hunt, binding her fate to Athena's, will come at a deadly cost-and it may not be enough to stop the rise of a new god with the power to bring humanity to its knees.
