Cornwall, 1793. As the French Revolution threatens the stability of England, so too is discontent brewing in the heart of Celia Cavendish. Promised to the brutal Viscount Vallenforth, she must find a way to break free from the bounds of a life stifled by convention and cruelty. Celia enlists her neighbours, Sir James and Lady Polcarrow, in the hope of escaping her impending marriage and making a new life for herself. But can the Polcarrows' mysterious friend Arnaud, captain of the cutter L'Aigrette, protect Celia from a man who will let nothing stand in the way of his greed? And will Arnaud himself prove to be friend…or foe?
