A Rogue by Any Other Name: The First Rule of Scoundrels (Rules of Scoundrels, 1)

"A decade ago, the Marquess of Bourne was cast from society with nothing but his title. Now a partner in London's most exclusive gaming hell, the cold, ruthless Bourne will do whatever it takes to regain his inheritance-including marrying perfect, proper Lady Penelope Marbury. A broken engagement and years of disappointing courtships have left Penelope with little interest in a quiet, comfortable marriage, and a longing for something more. How lucky that her new husband has access to an unexplored world of pleasures. Bourne may be a prince of London's illicit underworld, but he vows to keep Penelope untouched by its wickedness-a challenge indeed as the lady discovers her own desires, and her willingness to wager anything for them...even her heart."--P. 4 of cover.
