This was an erotic historical romance in which our heroine kidnaps the hero to hold him prisoner until she becomes pregnant. She needs a baby to be an heir to her elderly and ill husband's estate. She never expected to fall in love with the Duke she kidnaps. And he is not willing to leave her after he has fallen in love with her. While the story takes a lot of liberty with history, the erotic elements are very well done. This was a very hot read!
