Nine-year-old Anna Bauman is one of the Jewish children who Jolanta (code name for the real-life World War II Resistance spy Irena Sendler) smuggles out of the Warsaw ghetto. Anna, given a new name and false papers, must keep her true identity secret, first at a Catholic orphanage and then with a foster family. Ironically, she discovers that the most difficult part isn't remembering her new identity, but trying not to forget the old one. Anna's story, suspenseful and deeply moving, sheds light on yet another aspect of the Holocaust: rescued children who lost not only their loved ones, but their very identities and Jewish heritage.
