A Duke’s Winter Promise by Harriet Caves

It’s her last chance at love this winter—all she has to do is trap a duke.
Lady Louisa could never have imagined a fate worse than having to endure even a moment in Wyatt’s company of relentless teasing. Until her father suddenly died, her dowry evaporated, and her prospects disappeared.
Wyatt Fords, the Duke of Carriston, carries a secret which he has never shared with anyone. Not even to explain why he has changed into a cold-hearted rake. Or why he intends to die a bachelor and let the title pass to his cousin’s heir.
With an eventful ball marking the beginning of the Christmas holidays, Louisa is surprised to see that, despite his horrid reputation, Wyatt is still the same insufferable man that used to torment her. Only… This time the torment he provides is one she would very gladly submit herself to.
