I know several others answered your question, but I think the answer lies more in your own interests. If you are a Stephen King fan, you will greatly enjoy this series. The Gunslinger was, by far, the slowest-moving book of the series, and is a very poor indication of the other six books. The rest of them greatly pick up the pace, and IMO are fantastic. Again, if you aren't a King fan, then don't waste your time, as many of the references and allusions will mean nothing to you.
I am currently re-reading the Robert Jordan "Wheel of Time" series. Scooter, I think you would love this series. Greatest epic fantasy series I have ever read, and I am a fantasy nerd. George R. R. Martin's series is also good, and I would recommend both.
I would also highly recommend Battle Royale by Koushon Takami. It was also made into a movie (Japanese with English subtitles, I believe), but the book is, simply put, fricking out there...and it's tough to put down.
Sorry, I don't read non-fiction...reading is my escape from reality, and I like to get as far away as I can.
