They say love conquers all, but is it more powerful than revenge?A decade ago, Rex stole the heart of Mason's brother - literally - and Mason has never forgiven the wealthy assassin for taking that transplant. All he wants is payback for his brother's loss, but his every attempt has turned out like a bad prank.Rex knows what it's like to live on the dark side, and there's nothing he loves more than watching his beautiful good-guy with a vengeance play bad. So when Mason infiltrates Rex's black market company, the former assassin is perfectly happy with the idea of this innocently beautiful man stealing his heart away... at least until Rex realizes Mason's really after the newly developed transplant heart that he needs to survive.
