A little cat pinned with a star, a Nazi concentration camp and an opera production. This is the story of one girl's coming of age in Terezin.

Using toolboxes, ambulances, and other ingenious measures, Irena Sendler defied the Nazis and risked her own life by saving and then hiding Jewish children. Her secret list of the children's real identities was kept safe, buried in two jars under a tree in war-torn Warsaw. An inspiring story of courage and compassion, this biography includes a list of resources, source notes, and an index.
