HARDCOVER - When Hitler’s army entered and occupied his native Kraków, 10-year-old Yanek knew his life might change, but he had no idea of the horror that lay ahead. His remarkable survival story begins with a dramatic, emotional punch and then chronicles such moments as his secretive bar mitzvah in a warehouse basement, the systematic round up of Jews, and his deportation to the Plaszow concentration camp, the first of 10 camps he would suffer but survive. He recalls encounters with such Nazi figures as the sadistic Amon Goeth and describes acts of wanton, viscious brutality. In an appended note, Gratz explains that the novel is based on actual events in survivor Jack Gruener’s life but he has “taken liberties with some times and events” to provide a better overview. The account includes basic historical information including essential aspects of WWII.
