The Forever War by Joe HaldemanRead about another book on the list.
A classic Vietnam allegory that’s influenced many writers. The Forever War isn’t just an intelligent and dignified political commentary; it’s an engaging and personal science fiction novel that’s well done on every level. Haldeman breaks down the philosophy underlying modern militaries and the wars they fight, giving elegant and balanced acknowledgement to war’s necessity, and its absurdity. It’s a bit like Heinlein’s Starship Troopers, but with slightly more gravitas, and infinitely more soul.
The Forever War made Becky Ferreira's top ten list of best books for fans of The Twilight Zone, Emily Stamm and Charlie Jane Anders's list of the ten best science fiction stories where humans are the villains and Charlie Jane Anders's list of the 12 greatest science fiction war stories.
