25 years after her passing, Audrey Hepburn remains the most beloved of all Hollywood stars. Several biographies have chronicled her stardom, but none has covered her intense experiences through five years of Nazi occupation in the Netherlands. According to her son, 'The war made my mother who she was.' Audrey Hepburn's war included participation in the Dutch Resistance, working as a doctor's assistant during the 'Bridge Too Far' battle of Arnhem, the brutal execution of her uncle, and the ordeal of the Hunger Winter of 1944. She also had to contend with the fact that her father was a Nazi agent and her mother was pro-Nazi for the first two years of the occupation. Audrey's own reminiscences, new interviews with people who knew her in the war, wartime diaries, and research in classified Dutch archives shed light on the riveting, untold story of Audrey Hepburn under fire in World War II.
