For over a hundred years, vampire warrior Elsa Ware has worked alone, roaming the night to protect her race. When word of an underground fight ring using captive supernaturals reaches her clan, she is sent deep into a treacherous world where she will need all her skills to survive. But that's all part of her job. What she doesn't expect to find is an intense attraction to the sexy Russian werewolf who is the most feared fighter of them all. Sevastyan Rykov is undefeated in the bloody game he is forced to play, but when he is bitten by a demon in his last fight, it seems like a death sentence. Until the evil leader of the fight ring throws a beautiful vampire into his cell as the demon's poison turns him into a crazed predator. He can't control the bloodlust that rages inside him, but Elsa turns the need for violence into another kind of need altogether, and a connection is made...one that will either overcome the evil around them, or destroy them both.
