A secret she would die to keep.

A man who knows it.

The spy who promises to save her.

And a piece of paper that could set her free.

1945, Dresden, Germany. Ava is a high-priced courtesan and madame of her brothel, the Zwinger Bordell, an establishment designed for play in the midst of war. No other place provides a fountain of secrets and under-the-table dealings like the Zwinger. Jewish by birth, Ava has fought hard to keep her heritage a secret since the war broke out, along with the family she keeps hidden away from a quickly imploding Germany. But Lieutenant General Richter (a.k.a The Judge) knows of Ava's Jewish roots and wastes no time manipulating her into doing his bidding. Richter is hungry for power and he'll use anyone or anything to get what he wants.

Ava finds herself thrust into a game of cat and mouse as she hurries to help the Allied spies, Nathan Sinclair and Eddie Flannagan, who have promised to get her family out of Dresden, all before Operation Thunderclap drops, killing everything and everyone she loves. Will Ava find a way to keep her family safe? Can Nathan Sinclair be trusted? Or will her fight to save her family and herself be in vain?
