Starship troopers: Horrible movie, interesting read. Robert Heinlin or something along those lines is the author.
David Gemmell wrote a great series about the trojan war.. Troy: Lord of the Silver Bow, Shield of Thunder, and Fall of Kings.
I just finished Dennis Leary's- Why We Suck. If your a fan of his, its absolutely fantastic.
I saw Stephen King mentioned here.. Eyes of the Dragon is my personal favourite of his.
Also, not quite on the same level as far as in depth reading as some others, but for star wars fans, the Darth Bane trilogy is worth the read.
Rivet, check out those Gemmell books if you have the time, if your into the ancient mediterranean scene
