The Virgin and the Mob Boss by Alexa Riley

Pru has always been kept in the dark about her father’s business, even though she knows exactly what he does. When she finds out he’s going to marry her to another mob boss’ son, she’s had enough. Offering herself up to his rival is a risky move, but the way Vitaly Parlov looks at her makes her think it was the right one.
Vitaly Parlov is a man with a reputation, and he’s done what it takes to keep his power. When the daughter of his enemy offers herself up as a bride, he’s going to make sure she knows what she’s asking for. His instincts say to ruin her so he can get back at her father, but what if his need to keep her safe overcomes his need for vengeance?

Mafia boss with a heart of gold? Nah. Mafia boss with an over-the-top obsession for the woman he loves? YES PLEASE!
