Pride: The Rogue by Christi Caldwell

A merciless gaming hell owner
Born on the streets, Lachlan Latimer is neither a stranger to ruthlessness nor short on hatred for London’s wealthy elite. When he’d been young and desperate, he struck an alliance with three dukes. He even called them brothers. Now, rich, jaded, and life-hardened, he’s since learned his lesson. Unfortunately for his betrayers, Latimer’s gone rogue.

A lady with a plan
Born of questionable parentage, Miss Livian Lovelace straddles two worlds, but doesn’t truly belong to either. As a headstrong, unmarried, woman, it’s never been clearer just how much of an outcast she actually is. Too proud to spend the rest of her days reliant on the good-will of her family, Livian takes matters into her own hands.
When a chance meeting brings Lachlan and Livian together, passions fly. After one scorching night spent in the arms of the enigmatic, gaming hell, proprietor, Livian’s carefully laid plans go up in smoke. From the ashes, springs dreams of a future with the prideful, Lachlan Latimer.
