Jason Cummings, Duke of Rayne is feeling the weight of his responsibilities - one of which is to get married. Being the most sought after bachelor in London can be trying, so who can blame him if he seeks refuge from the voracious hordes of young debutantes at the decidedly female-free Historical Society? Female-free, that is, until Winnifred Crane marches up to the door, demanding entrance.

Despite her prowess as a historian, Winn is denied membership the Society. So she daringly offers an unusual bargain: if she can prove the authenticity of a certain painting, she'll be granted recognition, fame, and respect. But to do that, she must go abroad. And to go abroad, she must have an escort, even a stubbornly unwilling one...

Jason has no desire to accompany Winn on her adventure across Europe, but even he is not immune to Winn's passion for her profession. As the journey proves more difficult than planned, they must work together to stay one step ahead of their rivals.... and the closer they get to the proof Winn seeks, the closer she and Jason become. But as their adventure turns dangerous, can Jason keep this headstrong bluestocking safe? And what will become of their growing bond when the adventure ends?
