The Defiant Mistress (Harlequin Historical Series)

For eight years Gabriel Vaughan, Marquis of Halross, believed he was duped by a clever, money-grabbing harlot. Left at the altar, he was to witness his betrothed in the arms of another man. Now a chance meeting in Venice brings back all the old hurts and bitterness. Although Athena Fairchild claims to be innocent, maybe this is just another of her deceptions. It's time to exact a little revenge.
