Books like Seduced by Grace:(The Three Graces #3) by Jennifer Blake

When Lady Marguerite Milton is kidnapped by the enigmatic and famously insatiable Golden Knight, it is the stuff of fantasy. Or would be, if Marguerite weren't pining for her David, who promised his devotion ten years before and disappeared. But the only thing more heartbreaking than a man who doesn't keep his word is one bound by it. David is the Golden Knight, reaffirming his oath to protect Marguerite and, maddeningly, to love her, but chastely. More infuriatingly, Marguerite has been a pawn to lure David into King Henry VII's latest intrigue. To divide Yorkist insurrectionists, David is groomed as a rival to their latest pretender to the throne. Marguerite is desperate. If David fails, the rebels will destroy him; if he succeeds, Henry will not scruple to execute the would-be king he himself created. Suddenly, love and life seem far beyond the reach of any mere curse. This is the story of a forbidden romance that will test the boundaries of passion and loyalty in a world where every vow is worth more than a thousand words.
