Once a Bride by Shari Anton
Spirited, beautiful, and wealthy, Eloise Hamelin is shocked one day to find her father frantically preparing to leave their home. Accused of treason, he must flee and he orders Eloise to do anything necessary to save their estate, even cooperate with Roland St. Marten, the brother of her late betrothed. Sent by the King to oversee matters, Rowland had disliked Eloise at first sight. But now, as the tension surrounding her father's mysterious disappearance mounts, the sparks fly between Roland and Eloise. Her passionate and rambunctious nature that once drove him mad now only makes Roland want to help clear her father's name...and turn her growls into purrs.
