There's a hero and a villain in all of us....

Fighting the hunger is a daily battle for Mathias. It drives him to kill, to feast on the blood that sustains the demon within. There is no defeating it, so he channels it. Denying himself the allure of the innocent, he hunts the dregs of the Boston underworld, pacifying his demon with their bitter blood.

His latest prey may be his downfall. The vermin has a son—a golden child—with the sweetest blood Mathias has ever smelled. He struggles to keep his demon in check for fear a single mistake will shatter the remains of his humanity.
