They were teachers, students, chemists, writers, and housewives; a singer at the Paris Opera, a midwife, a dental surgeon. They distributed anti-Nazi leaflets, printed subversive newspapers, hid resisters, secreted Jews to safety, transported weapons, and conveyed clandestine messages. The youngest was a schoolgirl of fifteen, who scrawled “V” for victory on the walls of her lycee; the eldest, a farmer’s wife in her sixties who harbored escaped Allied airmen. Strangers to one another, hailing from villages and cities from across France, these brave women were united in hatred and defiance of their Nazis occupiers.  Eventually, the Gestapo hunted down 230 of these women of the French Resistance and imprisoned them in a fort outside Paris. Separated from home and loved ones, these disparate individuals turned to one another, finding solace and strength in friendship; their common experience conquering divisions of age, education, profession, and class.   In January 1943, they were sent to their final destination: Auschwitz. Only forty-nine would survive.  Interweaving original sources, archival research, and in-depth personal interviews, A Train in Winter is the riveting narrative of this remarkable band of sisters, patriots whose love fortified them in the face of deprivation, horror, and death.
