It's 1759 and the world is at war, pulling the North American colonies of Britain and France into the conflict. When captured French officers are brought to Long Island to be billeted in private homes, it upends the lives of the Wilde family. Lydia Wilde, struggling to keep the peace in her fracturing family following her mother's death, has little time or kindness to spare for her unwanted guests. And Canadian lieutenant Jean-Philippe de Sabran has little desire to be there. But by the war's end they'll both learn love, honour, and duty can form tangled bonds that are not broken easily. Their doomed romance becomes a local legend, told and re-told through the years until the present day, when conflict of a different kind brings Charley Van Hoek to Long Island to be the new curator of the Wilde House Museum. As Charley starts to delve into the history of Lydia and her French officer, it becomes clear that the Wilde House holds more than just secrets, and Charley discovers the legend might not have been telling the whole story.
