Since Hitmouse overwrote my numbers on page six of this thread in the post immediately after mine. Not to be a nitpicker, I honestly thought he posted at almost the exact same time as me and used the same numbers.
365. The Foundation Trilogy by Isaac Asimov (can't believe that's not on here yet)
366. Foundation's Edge by Isaac Asimov (counted separately, you can stop with that one which is best and the rest worse)
367. Different Seasons by Stephen King (my personal favorite of his, don't like some of his other stuff)
368. Chasm City by Alastair Reynolds (better than Revelation Space and should be read first. Kind of dark but brilliant)
369. Codex Alera by Jim Butcher (I liked the first two and they went downhill a bit after that but not too much)
