Homicide cop -- and werewolf -- Nick Lupo has battled other werewolves before, killers who unlike Nick have no problem hunting human prey. So when a new series of savage animal attacks terrifies the area, Nick already has a suspect in mind. And he knows that if he's right it'll be up to him to destroy her. But even as he begins his surveillance, someone else is out there, watching them both. Someone with a very deadly plan. Someone who knows just what it takes to kill a werewolf.
