'It's terrifying and incredible to think how much of this story is true' Elizabeth Wein, author of Code Name Verity on Prisoner of Night and Fog

Gretchen Muller has three rules for her new life:

1. Blend into the surroundings

2. Don't tell anyone who you really are

3. Never, ever go back to Germany

Gretchen Whitestone has a secret: she used to be part of Adolf Hitler's inner circle. When she made an enemy of her former friends, she fled Munich for Oxford with her love, Daniel Cohen. But then a telegram calls Daniel back to Germany, and Gretchen's world turns upside down when he is accused of murder.

To save Daniel, Gretchen must return to her homeland and somehow avoid capture by the Nazi elite. As they work to clear Daniel's name, they discover a deadly conspiracy stretching from the slums of Berlin to the Reichstag itself. Can they dig up the explosive truth and escape in time - or will Hitler find them first?
