Bella, a 15-year-old werewolf, has a problem: a mystical seal on her shoulder blocks her wolf and makes her weaker than the weakest omega. She's hunted by the Ancient Families, powerful werewolf bloodlines, because of the divine power hidden inside her. When her guardian gets killed protecting her, Bella's on her own, using poison and dirty tricks to survive. As the seal cracks, her wolf starts waking up. So does something ancient and hungry sealed beneath it. Bella's got to figure out her past, master her power, and become a threat before the Ancient Families find her. Because in a world of fangs and blood, the deadliest predator is the one nobody saw coming.
