I finished your book several days ago. I found it to be so interesting and thought provoking that I am presently re-reading some of the story based on notes I jotted down. I used the glossary prior to and after each chapter. TGDW is a great read, and I recommend it highly. I also will be providing your book as gifts to friends and family. Super job Ralph.
If I may, some additional praise for your book. Great job developing the characters. Having the pictures of them was a huge plus! Your insertion of humor as the story unfolded literally had me laughing out loud. With that said, the seriousness of the story was never lost. The comparisons of some events in the story to past unrelated events was masterfully accurate.
