Hanna Kaminsky loves gymnastics, her best friend Eva, Elza's chicken soup with dumplings and reading. But in September 1939 the happy life that Hanna has always known disappears. The Nazis have invaded Poland and are herding all Jews into ghettos in the cities. Hannas family are forced into hiding in the countryside. For a while it seems they are safe. But hiding from the Germans means trusting others. Rounded up by the SS, Hanna and her family are sent to the Warsaw Ghetto where they must use whatever skills they have to survive.
