Heartbroken and humiliated, she vows to forget the awful incident and avoid the high-and-mighty marquess like the plague. It should be easy enough to do - he is a busy man, after all, and she must secure a husband by the end of the Season or marry a man of her father's choosing. With no time to waste, she sets out to win a duke's heart and ignore, at all costs, the man who broke her own.Griffin, the Marquess of Keswick, wants nothing to do with Olivia Blakely. She might be beautiful, but she's also spoiled, and a title-chasing flirt to boot. Regrettably, she's also his sister's closest friend. When Griffin's mother suffers an injury that confines her to her bed, he is tasked with acting as his sister's chaperone, and wherever his sister goes, unfortunately, so goes Olivia.Thrust together against their will, proximity soon gives way to passion. But Griffin wants nothing to do with marriage, and Olivia wants nothing less than a duke. With the end of the Season fast approaching, will these two stubborn souls hold fast to their convictions...or finally give in to their hearts' true desires?This Marquess of Mine is a steamy Regency romance with a guaranteed happily-ever-after. It is the second book in the Romancing the Rogue series, but can be enjoyed as a standalone.
