Books like Lovefire by Deana James

FORBIDDEN DESIRE Lovely Princess Joanna couldn't stop the tumultuous emotions that surged through her heart when she first saw the knight Geoffrey Fitzjean. His sculpted face and virile frame made her ache to her very core. His golden hair and slate gray eves made her crave his tender caress. As the wife of the Duke of Brittany; the ebon-haired beauty couldn't dare a word--let alone a kiss--with her handsome subject. But as a passionate woman trapped in a loveless marriage, she couldn't bear the torment of one more lonely night without his rapturous touch! IMPOSSIBLE TO RESIST Geoffrey Fitzjean tried not to heed his treasonous thoughts of bedding luscious Joanna. But the more determined he was to deny his passion, the more fiercely his need grew to possess her. Just a glimpse of her creamy flesh and long raven tresses made him want to ravish her on the spot. Caught in the heat of desire, there was no turning back--he would chance a lifetime of imprisonment for one night as her master, consuming them both in the exquisite torture of their wild, raging LOVEFIRE
