Two women in Ravensbruck concentration camp in 1940 made a pact, that whoever survived would bear witness. Milena Jesensky, a journalist, and one-time translator and lover of Franz Kafka, and journalist Marguerite Buber-Neumann, were both arrested for their opposition to Nazism. Only Buber-Neumann survived.
Although the links to Kafka are interesting, it is the bond between the two women and the risks they took for their friendship that make this book so moving.
