Amelia Willoughby was engaged to the future Duke of Wyndham when she was just six months old. And now she's waiting—waiting for him to decide it's finally time to get married. But just when she asserts herself and begins to actually get to know her fiancé, his long-lost cousin appears on the scene, and no one knows for sure just which of them is the true duke. Has Amelia fallen in love with the wrong man? If she wants love, she's going to have to defy her family and take matters into her own hands.
