USA Today bestselling author Katherine Sutcliffe sweeps fans away to the passionate affair she began in Devotion, as one man's search for his lost love leads him to the heights of Obsession.

Trey Hawthorne, the Duke of Salterdon, once had a reputation that would humble the Marquis de Sade.

As he fights to rescue his beautiful Maria from a life of torment, Trey wonders if in saving her, he will also finally save himself -- or if the fight will cost him everything....
