Just found this thread. I feel like I've found my peoples. Although I've read most of these books a long time ago, I thought I'd give my 2 cents.
I second these books as great books to read:
Robert Jordan's Wheel of Time series
Ursula Le Guin's Earthsea books
T.H. White's The Once and Future King
and anything by Orson Scott Card
Marion Zimmer Bradley's trilogy (forgot the name though)
In addition I highly recommend:
Terry Brooks' Sword of Shannara series (fantasy) Society of the Mind
by Eric L. Harry (sci-fi thriller) Ishmael
or The Story of B
by Daniel Quinn (can't really categorize) Doomsday Book
by Connie Willis (sci-fi/fantasy) Prey
by Michael Crichton (sci-fi fiction)
OK, I could keep going but I'll stop. I guess I lied. ..So I gave you more like 10 cents.
I don't recommend The Chronicles of Thomas Covenant the Unbeliever by Stephen Donaldson. I have to admit while I was reading them, I just couldn't finish them fast enough, but if you don't like feeling depressed I suggest staying away from the Thomas Covenant series.
I just finished Angels & Demons
which I really liked - what a page turner - and plan on reading the DaVinci Code
sometime soon. Also reading Bringing Down the House
about a group of MIT students who make millions beating the system in Vegas and of course How to Get Into the Top Law Schools
