Disrupting the Duke by Alexa Aston

A brash army major who surprisingly becomes a duke. A lady who has no interest in ever wedding. An attraction that leads to passion . . . and love . . .

Cool, moody, and irresistible Donovan Martin finds himself the new Duke of Haverhill after his father and brother drown in a carriage accident. The womanizing Donovan decides to work his way through the numerous beauty of the ton because he has no intention of settling down. Until he encounters a most unusual woman—who informs him she never plans to wed.
Wynter Day wants to maintain her independence and never become subservient to any man. Besides, no man has ever sparked her interest romantically. Then the new Duke of Haverhill crashes into her life, causing Wynter to reconsider her stance on marriage.
A sprained ankle brings the pair closer together, with Wynter spending the Christmas holidays with Donovan and his friends. Sparks ignite and Donovan sees a future with Wynter. Then tragedy strikes, separating the couple, perhaps for good.
Will their stubbornness keep them apart—or will Donovan and Wynter let go of the ghosts of the past and take a chance on love?
