Antje Lange is in her early 40s when a phone call abruptly jolts her awake: "Were you born on July 17, 1941, in Danzig? Then I am your mother." This is how she learns out of the blue that she and her brother were adopted as young children. The image of a happy family shatters for her. Letters reveal the story behind the failed covert adoption: about Antje's biological mother, who never came to terms with the release of her baby and continually extorts new photos and reports. About Antje's social parents, who have tried to keep the secret for decades. And about the adoption mediator, who is caught in the middle. "Turning Point" is a touching novel interspersed with numerous original letters - and thus also serves as a snapshot of the early years of the Federal Republic.
