Vexing the Viscount — Emily Bryan

As children they'd sparred with play swords. She'd scarred his chin, and he broke her heart. Now, more than a decade later, the true battle was only beginning...

Daisy Drake needed Lucian Beaumont, Viscount Rutland. Tired of being labeled "on the shelf," she craved adventure. And Lucian held all the clues to a long-buried Roman treasure. Surely her desire to join his search had nothing to do with his dark curls and seductive Italian accent. Too bad Lucian wanted no help from her--until she donned the disguise of an infamous French courtesan and promised to teach him all she knew about the pleasures of the bedchamber. Of course, she only knew what had been written in naughty books. But Daisy had always been a quick learner. And night by naked night, they'd discover treasure neither expected to find.
