Lesse.. i've got a bunch. Heh.
Douglas Adams' Hitchiker's Guide is probably one of the best, heck, the whole series is good... Anne McCaffrey's Dragonriders of Pern series, LoTR trilogy (the Hobbit is alright, though you should read it first.) I honestly think the Silmarrillion is even better than the trilogy, but i know people who read the first three pages and fall asleep, so it's a matter of taste.. If you really like Tolkien, read the silmarillion... The Acorna series is quite good, by Anne McCaffrey and some other authors... hmmm...
There's this one other book that was outstanding, can't remember the name though. T'was about this society of psychics in the future, basically a communism because everyone was set positions in society, and people who weren't psychics were executed.. There was a wall around this, and outside were the normal people that had survived a massacre, one of the psychics got stuck out there and ended up forming a friendship with this wild girl.. Gah. Anyone know what i'm talking about?
