Margarete Buber, the journalist daughter of Martin Buber, and Milena Jesenska, the beautiful lover of Kafka, met in Ravensbruck concentration camp in 1940. For four terrible years, the two women formed an extraordinary bond and made a pact that if only one survived, the other would bear witness. Only Margarete lived to remember. This is her story of Milena—of fearless love, sacrifice, and nobility.
