I am also stunned by the sacrifices made by our armed forces, and also by our citizens. Our country had one focus, and everyone worked together to beat Hitler.
Some other unique books you may enjoy are Last Train to Istanbul, by Ayse Kulin, a book about trying to save Turkish Jews during WWII, City of Thieves by David Benioff about the Leningrad winter holding out from Hitler, The Invisible Bridge by Julie Orringer, about a Hungarian Jewish Family, The Siren of Paris by David LeRoy about a man's experience in Paris during the German occupation.
Those books are lesser known, but still great fictional reads about what life was like during WWII. Some bestsellers that you probably know are Sarah's Key by Tatiana de Rosney, and The Book Thief by Markus Zusak. There's a reason those books were best sellers, and should be read if you haven't already.
So thank a veteran, and try to remember the difference between hardship and inconvenience. Thanks to our veterans, most of us have never experienced true hardships.
