Definite musts are Starship Troopers by Heinlein and my favorite which is kinda underscored.... The Forever War by Joe Haldeman...
Gaunt's Ghosts by Dan Abnett set in the Warhammer 40,000 universe is probably my favorite series.... Right next to Starfist...
Classic Joke is how Abnett introduces a superficial character (read: Cannon Fodder) and they get killed a paragraph later... or in the paragraph they are introduced.... Me and my friend jokes about it all the time....
I just read The Forever War on your recommendation, barcelonablom. Thanks for recommending it. I enjoyed it greatly and finished it in just over 1 day. Interesting to see what he thought the time period might be like now (especially because I live about 20 minutes from Columbia, MD).
