Kerensa Trelynne's plans to wed her sweetheart, Clem Trenchard, are ruined when Sir Oliver Pengarron makes her grandfather, and guardian, an offer for Trelynne Cove - the land on which Old Tom's cottage stands. Old Tom is wily, and to ensure a secure and stable future for his precious granddaughter, he makes her part of the price for the Cove: Sir Oliver must marry Kerensa.
Pengarron is horrified but, pragmatic to the last, agrees to the deal, and the distraught Kerensa has to learn to live with the consequences of an unwanted marriage. As the months pass, they begin to trust one another. But will she ever forget the old loyalties that linger?
