Bound by a Dragon by Linda K. Hopkins

Life is not all rainbows and sunshine in the small, medieval village where Keira Carver lives. First of all, her mother wishes her to marry a man she detests, and then a huge fire-breathing, flesh-eating dragon takes up residence in the mountains. But when a handsome stranger walks into the market one day, his gaze fixed solely on her, life is about to become a whole lot more interesting.
