This house in the small Austrian town of Amstetten became famous overnight: Despite police prohibitions, tourists took photos and sketches of the facade for a long time. And in the bunker under the house there was hell for almost a quarter of a century. Here, from 1984 to 2008, a simple electrician, Joseph Fritzl, kept his own daughter captive and regularly raped him, and with her, not knowing sunlight, the children born from unnatural intercourse languished. This book explores torture, violence, suffering, but also the ultimate triumph of the human spirit of a mother and her children who went through hell but found the strength to live on.
