Vienna, 1930s. The Kleinmann family live a simple, ordinary life. Gustav works as a furniture upholsterer while Tini keeps their modest apartment. Their greatest joy is their children: Fritz, Edith, Herta and Kurt. But after the Nazis annex Austria, the Kleinmanns' world rapidly shifts before their eyes. Neighbours turn on them, the business is seized, as the threat to the family becomes ever greater. Then, they discover that Gustav will be transferred to Auschwitz, a certain death sentence, and Fritz is faced with a choice: let his father to die alone, or join him... Based on Gustav's secret diary and meticulous archival research, this book tells the Kleinemanns' story for the first time—a story of love and courage in the face of unparalleled horrors.
