Graycourt Series 2: When A Rogue Meets His Match - Elizabeth Hoyt

Ambitious, sly, and lethally intelligent, Gideon Hawthorne has spent his life clawing his way up from the gutter. For the last ten years, he's acted as the Duke of Windemere's fixer, performing the most dangerous tasks without question.

Now Gideon's ready to quit the duke's service and work solely for himself. But Windermere wants Gideon to complete one last task, and his reward is impossible to resist: Messalina Greycourt's hand in marriage. Witty, vivacious Messalina Greycourt has her pick of suitors.

When Windermere summons Messalina to inform his niece that she must marry Mr. Hawthorne, she is appalled. But she's surprised when Gideon offers her a compromise: as long as she plays the complacent wife, he promises to leave her alone until she asks for his touch.

Since Messalina is confident that she'll never ask Gideon for anything, she readily agrees. However, the more time she spends with Gideon, the harder it is to stay away.
