The award-winning international sensation that poses the question: Was Sigmund Freud responsible for the death of his sister in a Nazi concentration camp?

The boy in her memories who strokes her with the apple, who whispers to her the fairy tale, who gives her the knife, is her brother Sigmund.

Vienna, 1938: With the Nazis closing in, Sigmund Freud is granted an exit visa and allowed to list the names of people to take with him. He lists his doctor and maids, his dog, and his wife's sister, but not any of his own sisters. The four Freud sisters are shuttled to the TerezГЊn concentration camp, while their brother lives out his last days in London.

Based on a true story, this searing novel gives haunting voice to Freud's sister Adolfina - "the sweetest and best of my sisters" - a gifted, sensitive woman who was spurned by her mother and never married. A witness to her brother's genius and to the cultural and artistic splendor of Vienna in the early 20th century, she aspired to a life few women of her time could attain.

From Adolfina's closeness with her brother in childhood, to her love for a fellow student, to her time with Gustav Klimt's sister in a Vienna psychiatric hospital, to her dream of one day living in Venice and having a family, Freud's Sister imagines with astonishing insight and deep feeling the life of a woman lost to the shadows of history.
