I read the foundation trilogy by Issac Azimov (the original rilogy included Foundation, Foundation and Empire, and Second Foundation), IT WAS AWESOME!!!! I started reading it because I heard it was the basis for ALOT of other works I like. This series was written 50 years ago and that actually makes it better. I know alot of people who are put off by Sci Fi now because modern stuff is all rip-offs of star wars and star trek, but this old stuff was way before all that, back when you needed plot. I'd highly recommend.
