The Hostage Heart — Lynn Errick

Lady Chryssa of Glennewald was everything a proper Norman noblewoman should have been, her brother had seen to that after their parents' death. Good manners and a sense of duty were no match for the brawny Saxon knight, however.
Plucked from a crowded London marketplace, lovely Chryssa was at the mercy of Garrett of Thornhurst, a man bent on taking revenge against her brother. Infuriated, and intrigued by her gruff jailer's gentle kisses, Chryssa vowed that Garrett would pay for his deeds, with his hand in marriage.
