Isola, heir to the werewolf alpha, and Kaelan, crown prince of the vampires, meet as enemies on the battlefield, only to save each other's lives. Their forbidden love makes them the target of all three clans. Hunted even by their own families, they uncover the truth: the thousand-year war was orchestrated by Kaelan's father, High Sovereign Valentin, who feeds on the hatred born of conflict to ascend to godhood. To stop him, Isola and Kaelan must fuse their opposing bloodlines, unleashing a power that consumes their memories and shortens their lives. They choose to pay the price. Love above all.
