Lady Grace Mabry's ample inheritance has made it impossible for her to tell whether a suitor is in love with her or enamored of her riches. Who better to distinguish beau from blackguard than her notorious childhood friend, the Duke of Lovingdon. With no interest in marriage, Lovingdon has long lived only for pleasure. He sees little harm in helping Grace find a proper match. He simply has to teach the lovely innocent all the ploys a scoundrel uses to gain a woman's favor--by demonstrating his wicked ways. But as lessons lead to torrid passion and Grace becomes ensnared in another man's marriage plot, Lovingdon must wage a desperate gamble: open his heart fully--or risk losing the woman he adores.
