Billie first met Royce at Wulf's Den while there to drag her drunken brother home to his wife. Even though she knows he is attracted to her, Royce refuses to see her again. With four older brothers, and being a personal trainer at her family's gym, Billie is not the type of woman to let a man she wants slip through her fingers. Royce knows Billie is his mate, but with her being a mortal, he fights the attraction he feels for her. He already lost a mate who wasn't a werewolf and doesn't want to take the chance of getting hurt. As Royce's feelings grow for Billie another male werewolf stalks Royce. Thinking Royce's blood is the key to a magic spell, he will do anything to obtain it, even if he has to use Billie to get it.
