Elena Michaels and her werewolf pack team up with a family of Mutts (werewolves who don't belong to any pack) to attempt to track a group of werewolf-killers.

The Cains are a mutt clan, and are known for being big, brutish and not-too-bright; they embody all the worst stereotypes about werewolves. But not even the Cains deserve to be hunted down and skinned like animals. When Davis Cain comes to the Pack for help, Alpha Elena Michaels can't refuse him. But Elena is also dealing with Malcolm Danvers, onetime enforcer, full-time psycho. If Elena has to let Malcolm in, she's going to make full use of him... and the best person to catch monsters is one who knows exactly how they think.
