Miss Caroline Sloane is on her way to Poughill, Cornwall. In highhanded fashion, her estranged grandfather has arranged a marriage for her to a sea captain she's met but once, and she wishes to convince him otherwise. She'll marry for love or not at all, but an accident with the crowded mail coach on which she's traveling throws her existence into chaos.

Alan Blackmore, the Earl of St. Clair, has been summoned to his Devon estate by his ducal father. His engagement, designed by the duke years ago, has now come due and he must wed to merge holdings. The last thing he wants is a leg-shackling, for he enjoys his life of a rake too much, and he means to tell his father off, but one dark, rainy night on mud-slick roads changes his course forever.

Lost and injured in windswept and rugged Cornwall, the first order of business is survival. As their wounds heal, Caroline and Alan come to know each other while living a simple, uncomplicated life. A friendship of necessity slowly grows into something passionate and scandalous, but when reality returns to rescue them, they both must decide what is more important: duty, tradition, or an unexpected love.
