The Duke's Foolish Heart — Karen Lingefelt

Sophie Patton needs a temporary fiance so her spoiled younger sisters can visit London to find husbands before they're as old as she is. Enter Troy Griffin, Duke of Ainsley, a notorious rake wrongly accused of abandoning his former fiancee and killing another man in a duel. Sophie boldly proposes a false betrothal to Troy, arguing it will redeem his tarnished image once she jilts him for her real beau who's traveling abroad. Impressed by her honesty and audacity, he agrees. They take London by storm and fight a growing attraction. When she learns her beau married someone else, Sophie fears Troy will think she tried to trap him into making her a duchess, and since he allegedly jilted a woman before, he's sure to do it again. Unable to face another betrayal, she resolves to end their betrothal as they previously arranged. But the duke's foolish heart has been broken before-and His Grace will not be fooled again.
