Miss Kira Melbourne is anything but a proper English rose. Her exotic beauty, courtesy of her foreign mother, has marked her as an outsider, and her ghastly reputation as a woman of loose virtue has only added to that status. The victim of a devious viscount's horrible lies, Kira has the chance to redeem herself and become a member of polite society as the fiancée of a respected country clergyman. She'll finally have a place to belong...even if it's in the tepid arms of a man she doesn't love.

Gavin Daggett, Duke of Cropthorne, isn't about to let his naive country cousin marry a scandalous woman like Kira Melbourne. The solution is a simple one: Gavin will seduce the vixen and prove her unworthiness, thereby releasing his cousin from any obligation. But spending time with Kira is like awakening to a world of color and beauty, and it stirs the fiery desires Gavin has fought to suppress his entire life. Caught in his own dangerous game, sharing forbidden pleasure with Kira, Gavin knows that the price of loving her is high—and yet it is one that he will willingly pay...with every beat of his heart.
