In 1912, a well-known doctor and writer named Janusz Korczak designed an extraordinary orphanage for Jewish children in Warsaw, Poland. Believing that children were capable of governing themselves, he encouraged the orphans to elect a parliament, run a court, and put out their own weekly newspaper. Even when Korczak was forced to move the orphanage into the Warsaw Ghetto after Hitler's rise to power, and couldn't afford to buy food and medicine for his charges, he never lost sight of his ideals. Fully committed to giving his children as much love as possible during a terrifying time, Korczak refused to abandon them. In his most beautiful and heartfelt book to date, Tomek Bogacki tells the story of a courageous man who, during one of the grimmest moments in world history, dedicated his life's work, and ultimately his life itself, to children.
