A young Jewish boy escapes the ghetto and finds a group of resistance fighters in the forests of Poland, and he must determine if he has what it takes to survive the Nazis and fight back.

From 1939, when Syvia is four and a half years old, to 1945 when she has just turned ten, a Jewish girl and her family struggle to survive in Poland's Lodz ghetto during the Nazi occupation.

In 1942 sixteen-year-old Chaya Lindner is a Jewish girl living in Nazi-occupied Poland, a courier who smuggles food and documents to the isolated Jewish ghettos in southern Poland, depending on her forged papers and "Aryan" features--but when a mission goes wrong and many of her colleagues are arrested she finds herself on a journey to Warsaw, where an uprising is in the works.

Based on the life of Jack Gruener, this book relates his story of survival from the Nazi occupation of Krakow, when he was eleven, through a succession of concentration camps, to the final liberation of Dachau.
