The Seduction of an English Scoundrel (The Boscastles #1)

It would have been the wedding of the year–had the groom, Sir Nigel Boscastle, bothered to put in an appearance. To the shock of her distinguished guests, the respectable Lady Jane Welsham is left humiliated at the altar. Yet truth be told, although outwardly ruined she is elated to have escaped marriage to a man she does not love.
Enter Grayson Boscastle, the irresistible Marquess of Sedgecroft (and cousin to Nigel). Grayson’s duty is clear: salvage the young lady’s pride and reestablish the family’s good name, while repairing his own tarnished reputation as one of London’s most notorious scoundrels. Their whirlwind affair is the talk of the ton. Yet nothing is as it seems between the bewitching Lady Jane, who knows that her wedding was cleverly sabotaged, and her charming rogue, as they are drawn into an amusing game of seduction and secrets
