Never Judge a Lady by Her Cover (Rules of Scoundrels Series #4)

By day, she is Lady Georgiana, sister to a duke, ruined before her first season in the worst kind of scandal. But the truth is far more shocking—in London's darkest corners, she is Chase, the mysterious, unknown founder of the city's most legendary gaming hell. For years, her double identity has gone undiscovered . . . until now. Brilliant, driven, handsome-as-sin Duncan West is intrigued by the beautiful, ruined woman who is somehow connected to a world of darkness and sin. He knows she is more than she seems, and he vows to uncover all of Georgiana's secrets, laying bare her past, threatening her present, and risking all she holds dear . . . including her heart.
