The untold story of Mildred Harnack， an American woman who was the leader of the largest anti-Nazi resistance group in Germany， a role she was later executed for。
Mildred Harnack was a leader of the largest anti-Nazi resistance group in Germany。 That she was a woman distinguished her from many of her contemporaries in the male-dominated leadership of the German Resistance。 That she was an American was even more notable。 Born and raised in Milwaukee， she risked her life to fight a murderous dictator on foreign soil， a feat of enduring historical significance。 Contemporary historians identify her as the only American in the German Resistance， yet she remains almost entirely unknown。
Mildred was twenty-six when she moved to Berlin and witnessed first-hand the horrors of Hitler's ascendancy。 For nearly a decade---from 1933 until 1942---she devoted herself to defeating him。 She wrote and distributed leaflets exposing Nazi atrocities to incite civil disobedience， helped Jews and political dissidents escape Germany， and delivered top-secret military intelligence about the Nazi regime to the Allies。

Based on years of original research and exclusive interviews with those who knew Mildred personally， Rebecca Donner， Mildred's great-great niece， at last tells Mildred's remarkable and heroic story。
