Gently bred Emma Chadwick always assumed she'd live and die the daughter of a gentleman. But when her father's death reveals a world of staggering debt and dangerous moneylenders, she must risk her good name and put her talent for mathematics to use, taking a position as bookkeeper at London's most notorious gambling hell. Surrounded by vice and corruption on all sides, it is imperative no one discovers Emma's shameful secret or her reputation—and her life—will be ruined.
But Roderick Bentley, the hell's sinfully wealthy owner, awakens a hunger Emma cannot deny. Drawn deep into an underworld of high stakes gambling and reckless overindulgence, she soon discovers that in order to win the love of a ruthless scoundrel, she will have to play the game and give in to the pleasure of falling from grace.
