Glamour, treachery, and espionage collide when an English socialite rushes to save her sister from the Nazis.

As the daughter of Sir Alfred Whitford, Kat has a certain set of responsibilities. But chasing her wayward sister, Ellie, to Nazi-occupied Paris was never supposed to be one of them. Now accustomed to the luxurious lifestyle that her Nazi boyfriend provides, Ellie has no intention of going back to the shackled life their parents dictate for them - but Kat will stop at nothing to bring her sister home.

Arrested for simply trying to defend himself against a drunken bully, Barrett Anderson is given the option of going to jail or serving out his sentence by training Resistance fighters in Paris. A bar owner serves as the perfect disguise to entertain Nazis at night while training fighters right below their jackboots during the day.

Being assigned to watch over two English debutantes is the last thing he needs, but a payout from their father is too tempting to resist. Can Barrett and Kat trust each other long enough to survive, or will their hearts prove more traitorous than the dangers waiting around the corner?
