**Written by the author of* The Metamorphosis and The Trial—* one of the greatest writers of the twentieth century—between 1909 and 1924, these letters offer a unique insight into the workings of the Kafka family, their relationship with the Prague Jewish community, and Kafka’s own feelings about his parents and siblings. Kafka’s touching letters to his sister, when she was a child and as a young married woman, are beautifully simple, tender, and fresh. — *The New York Review of Books* ** A gracious but shy woman, and a silent rebel against the bourgeois society in which she lived, Ottla Kafka was the sibling to whom Kafka felt closest. He had a special affection for her simplicity, her integrity, her ability to listen, and her pride in his work. Ottla was deported to Theresienstadt during World War II, and volunteered to accompany a transport of children to Auschwitz in 1943. She did not survive the war, but her husband and daughters did, and preserved her brother’s letters to her. They were published in the original German in 1974, and in English in 1982.
