To protect the dukedom from an incompetent and greedy cousin, Daniel Hayle, Duke of Carlisle, has promised to find a bride in London this season. But the idea of facing ballrooms and card parties is as intimidating as any battlefield in France, including the fight at Waterloo that left him terribly scarred. Perhaps a month on the Isle of Synne can provide him with the practice necessary to find a wife who can tolerate him enough to give him an heir.
Margery Kitteridge has been mourning her husband for four years, and while she's not ready to consider marriage again, she does miss intimacy with a partner. When Daniel asks for help navigating Synne's social scene, and they accidentally kiss, she realizes he's the perfect person with whom to have an affair. As they begin to confide in one another, Daniel discovers that he's unexpectedly connected to Margery's late husband, and she will have to decide if she can let her old love go for the promise of a new one.
