She was too young for a man my age, barely in her twenties. Far too pure and untouched. Unfortunately for her, that wasn't going to stop me. The moment I laid eyes on her, I claimed her. Determined to make her mine… by any means necessary. I owned Chicago's most elite gambling club, a front for my role as a Russian Mafia crime boss.  She was a fragile little bird who had just flown straight into my open jaws. Naïve and sweet, she was a temptation I couldn’t resist biting. My intense drive to dominate and control her had become an obsession. I would ruthlessly use my superior strength and wealth to take over her life. The harder she resisted, the more feral and savage I would become. She needed to understand… she was mine now. Mine. Sweet Intensity continues the steamy, enemies-to-lovers drama featuring the domineering Russian Mafia men of the Ruthless Obsession series. This is the sixth book and part of a new trilogy inside the series. It is a standalone that contains adult themes.
