The French women who defied the Nazis and survived Auschwitz

Caroline Moorehead's book, A Train in Winter, takes a different approach to the Nazi occupation of France during World War II.

In it she tells the story of a group of 230 French women deported to Auschwitz-Birkenau together in January 1943.

Only 49 of the women survived the infamous brutality of the concentration camp, but A Train in Winter is not a story about victims. Instead the book celebrates the spirit of resistance and friendship that persisted, despite the hardship, among these heroines of World War II.
