While vacationing on Gambler's Folly with her husband, Trae, Karianna O'Brien's life is ripped apart when he loses her to Damiano Leone in a game of chance. Within two days, she is divorced, widowed, and married to Damiano, the darkly desirable, powerful and dangerous lord of the underworld.

Irresistibly drawn to Damiano, Karianna enters his world of wealth and glamour, while he teaches her the meaning of pleasure and sensuality in his bed. Though married to Trae for four years, she's never experienced true seduction, or sex so exquisite it could become an addiction. Is he really human, or something else?

As Damiano's enemies threaten Karianna to leverage his vote in the syndicate, he gambles all he's worth in a dangerous game of skill. Will his plans pay off in time to save Karianna? Or will he lose both his business and his soul mate?
