Matt Rowley hasn't been human for years. A commando for the International Council on Augmented Phenomena, he hunts down superhuman monsters the military can't handle. But his abilities come with a price: bloodthirsty whispers that urge him to acts of terrible violence. An encounter with a giant, angelic being with wings of smoke and shadow casts him into a world of inhuman brutality, demonic possession, and madness, where he must choose between his family and his soul.
