The Marker - Blood and Betrayal Series, #1

Shelley De Luca has a problem. A large, man-size one in the form of the older brother of her dead high school sweetheart. She owes him a marker, and he intends to collect. In the biblical way. Sure, he's dangerous, a jerk and a player, but he's also gorgeous, sexy and secretly the man of her dreams. Except for the small matter of her heart, paying him back should be easy. Gianni Cadora is mafia trying to go legit.
When Shelley stumbles back into his life, she comes with bruises, a psycho ex and a spicy attitude he can't resist. He's man used to getting his way, so why is it so difficult to convince Shelley he's what she needs? Perhaps it's their history, or his reputation, but he isn't above using his marker or a funny, flatulent dog to get what he wants.
