Something Wicked This Way Comes - The Brides of North Barrows, #1

Seven years ago, Sophia Brisbane lost everything-her father, her brother, her family fortune-but worse, was rejected by the man she loved. She's determined not to yearn for the past and its pleasures-until she encounters Lucien de Roye again. Although he knew Sophia could never be his own, Lucien vowed to retrieve her squandered inheritance-even wagering his very soul to a demon. When Sophia learns what he has done, no force on heaven or earth will convince her to let him pay the demon's due, no matter what the cost to herself.
