Johnny Got His Gun, by Dalton Trumbo
Rightly considered an anti-war novel masterpiece. One of those works that should be read by all Americans, heck, all Humans. Even if you consider yourself a hawk, you should read this to get an idea where 'those crazy anti-war peaceniks' are coming from.
It's a quick read / page turner. I give it 5 stars, no hesitation.
