There's fighting, and then there's bare-knuckle, hold nothing back fighting... Sunny McGrieve has lived around fighters her whole life. With her dad training ruthless men who excel in MMA and fight in the underground circuit, she is no stranger to violence. But her father has warned her about that breed of male, and that means the man she wants, London Stein, is out of the question. London enjoys women like he does his fights: hard and fast, and with no regrets. Then there is Sunny, the girl he wants but can't have. When he finally has her, London knows that he has no intention of letting her go. But her dad and Mack, the big Russian that sees her as a little sister, aren't his only problem, not when he has been challenged by a no-rules fighter, "The Lion".
