Every full moon draws Marcus Shaw closer to the truth of his identity. When a violent armed robbery triggers his dormant werewolf nature, his seemingly perfect life begins to fall apart. He is haunted by recurring nightmares of his mother fleeing from silver-armed hunters, experiences blackouts, and, most troubling of all, faces a growing number of mutilated bodies he cannot recall creating.
Now, his adoptive father, the city's leading detective, is on the trail of a killer who leaves behind claw marks and shattered bones. Marcus's only ally may also be his greatest danger – Emma Blackwood, whose father once led the massacre of his entire pack and continues to hunt their kind.
As the moon grows fuller and the body count rises, Marcus must confront the beast within him before his two worlds collide. In a city where werewolves are the hunted and humans are the hunters, survival may require him to embrace the very monster he fears becoming.
