The Granddaughter By Bernhard Schlink

In search of love and freedom, Birgit flees to Kaspar in West Berlin. It is only after her death that Kaspar discovers the price she paid to get there. He sets out to uncover her secrets in the East, meeting those she cared about, witnessing their oppression and determination first-hand. His search leads him to a rural community of neo-Nazis, and to a young girl who comes to think of him as a grandfather. Their worlds could not be more different – but he is determined to fight for her. He, too, considers her a granddaughter.
