Two months after giving birth, Scarlett is betrayed by her fiancé Desmond, who offers her as a sacrifice to a blood witch. She blinds him in one eye, grabs her baby daughter, and leaps off a snow cliff, only to be rescued by Valen, the Wolf King of the Northern Realm, and taken to his wolf stronghold.
With just one tiny hand, the infant Aurelia can calm the Wolf King’s berserk rages. She also bears three soul-devouring blood curses that fade with each passing moon. The wolf clan’s ancient laws, invading foes, and the blood witch all seek the mother and daughter’s lives. Time and again, Valen risks his throne and his life to protect them. Scarlett, in turn, claims the Northern Realm through herbal remedies, hard evidence, and unyielding choices. She swears to rewrite the ancient rule that demands one life be claimed before the third full moon rises.
