Book excerpt: When Hannelore Zack left Cologne, Germany, on July 24, 1939, she had no way of knowing that she was part of the Kindertransport, an epic rescue effort that would save 10,000 Jewish children from Hitler's Nazi regime by granting them safe passage to England. After being stripped of their business, forced from their home, and deported to endure six months of inhumane conditions in the Lodz Ghetto, her parents were gassed in a brutally efficient killing operation in a remote forested area near Chelmno, Poland, on May 3, 1942. Written over a four-year period beginning when Hanna was about seventy-five years old, this is both a gripping detective story recounting the heartbreaking process of discovering her family's fate and a poignant account of her journey from vengeful hatred to forgiveness.
