Warrior: Audrey Hepburn completes the story arc of Robert Matzen's Dutch Girl: Audrey Hepburn and World War II . Hepburn's experiences in wartime, including the murder of family members, her survival through combat and starvation conditions, and work on behalf of the Dutch Resistance, gave her the determination to become a humanitarian for UNICEF and the fearlessness to charge into war-torn countries in the Third World on behalf of children and their mothers in desperate need. She set the standard for celebrity humanitarians and--according to her son Luca Dotti--ultimately gave her life for the causes she espoused.
