On the eve of her profession as a nun, Lady Graeye Charwyck is called home to Medland by the father who disavowed her years earlier for the “devil’s mark” she bears. Desperate to escape the convent, she agrees to wed a man she detests to provide an heir for her family’s holdings. But when the king declares the Charwyck lands forfeit and awards them to their enemy, Graeye once more finds herself discarded. Grieved by her father’s plans to return her to the convent, she yields to impulse and casts aside her virtue, only to discover that the knight with whom she sinned is the new lord of Medland.
