My Fair Princess, by Nona M. King

Nia is the only daughter of Alaerian King Thaedis. To benefit the realm and expand trade, she is betrothed to the mayor of a blossoming town in a neighboring district sight unseen. After her childhood fantasies of finding true love the betrothal is a bitter pill to swallow, but then she meets her mysterious husband-to-be. With his unruly shock of auburn hair and easy going manner, Shamus O’Neill is a handsome and endearing alternative to the decrepit mayor of her imagination.
