Margarete Buber-Neumann was a German communist who was called to Russia to work as translators at the Foreign Workers Publishing House. After her husband, Heinz Neumann was executed in Stalin's purges, Margarete was interned at the Lubianka prison, then Butyrka, and then sent to labour camps.
She was subsequently exchanged with German prisoners in an exchange pact with Germany and she was sent to a Ravensbrück concentration camp in February, 1940. There she met Milena Jesenska and they became friends.
Milena is the story of their friendship won through the greatest of hardships.
