When her only lead is killed in front of her by a pair of Hunters, she seizes the opportunity to learn from the battle-scarred brothers. Annie gets more than she bargains for when she falls for one of them.   Rhys and Owen Carter take a detour to a small Arizona town to stop a werewolf. The headstrong witch they save from the creature brings chaos into their lives when they decide to teach her about the things that go bump in the night. It might be the best idea ever or the worst, but they can't let Annie face the monsters on her own.
