James Cordier is a master of intrigue, a brilliant thief, a first-class lover, and an intimate friend of danger—all for King and Country—and thoroughly sick of it. He just has to complete one last mission, and then he can retire peacefully, and resume his aristocratic life in Regency London, where his most dangerous task will be courting sweet, respectable heiresses. But first, James must charm a set of incriminating letters from a woman who is anything but quiet or respectable: the notorious Francesca Bonnard...

Francesca Bonnard has overcome heartbreak, scorn, and scandal to become independent, happy, and definitely fallen! She's learned the hard way that "gentlemen" are far more trouble than they're worth, so she can certainly see that her wildly attractive new neighbor is bad news.

But as bad as James is, others—far worse—are also searching for Francesca's letters. And, as James and Francesca are thrust ever closer, suddenly nothing is simple—especially the nearly incendiary chemistry between the two most jaded, sinful souls in Europe. And just as suddenly, risking every danger seems to be worth every reward.
