Lioness werewolf Scarlett Milan hates that she wants her boss more than her next breath. All she thinks about is that his black-framed glasses and bow tie look sexier on him than on any other man. But since he's human, she's afraid she might break him, even kill him, during a night of wild sex. Knox Daniels, a law-abiding investment banker, lusted after Scarlett from the moment he met her. The fact that she was his best friend's little sister stopped all lustful thoughts. Almost. After he breaks up with his girlfriend, the first thing he has to do is get Scarlett. Being killed is not. A brutal attack nearly kills Knox, but science comes to the rescue. Now he is no longer the weak person Scarlett was afraid to touch. No one really knows who he is other than possessive, aggressive and demanding that she belong to him. They will have to team up to keep him alive while they discover whether he is a crazed killer or simply the most powerful alpha known.
