A vampire joins forces with his fated woman to battle the evil that transformed his life in this romantasy novel.

As a vampire and a warrior, Leto Distra is deadly. But after years of being forced to drink dying blood, he is now part beast—a wild savage thing lurking beneath the surface. With war on the horizon, Leto is determined to help the Guardians of Ascension destroy the enemy who turned him into a monster. And there's only one woman who can help him.

Grace Albion is certain that she's meant to be with Leto, but their future may be cut short by the impending battle. Now Grace must embrace her obsidian flame powers—and bind her powers with Leto's—if they're ever going to survive. With the fate of the world at stake, they must tap into powers they never knew they had . . . and unlock their deepest passions.
