The Last Witness is better classified under Holocaust first, and then mystery. This imagining of the world in 2039, when only a few survivors of the Jewish Holocaust remain. if any, is clever, and a timely message - if we do not honor history, remember history, write it down, and teach it, the memories will be lost, and Holocaust deniers will indeed prevail in textbooks and classroom teaching. It was a fast read for me, as I'm well-researched on WWII and Auschwitz, and Jerry's history is spot on accurate. That he wrote it as a thriller falls under creative writing, and in doing so, is actually spreading Holocaust awareness to those who may not be drawn to a "Holocaust" or Auschwitz book. The reader needn't worry about grim scenes in a concentration camp - these are only short flashbacks as reminders of what really happened. It's written well, and the thriller aspect (no spoilers here) is completely realistic and spot on based on what's happening now in the world, a mere three years after he wrote - 5 star review Amazon
