The Last Witness — Jerry Amernic

The year is 2039, and Jack Fisher is the last living survivor of the Holocaust. Set in a world that is abysmally complacent about events of the last century, Jack is a 100-year-old man whose worst memories took place before he was 5. His story hearkens back to the Jewish ghetto of his birth and to Auschwitz where, as a little boy, he had to fend for himself to survive after losing his family. Jack becomes the central figure in a missing-person investigation when his granddaughter suddenly disappears. While assisting police, he finds himself in danger and must reach into the darkest corners of his memory to come out alive.
