I remember the first time Martin killed a major character. At first I was like, OH SHIT. You know, like that kid in The Neverending Story ? I jumped up, threw the book down, and ran out of the room. Then, peering back into the room, saw that I had an awesome book to finish. And it was awesome.

If we're doing recommendations, I would strongly suggest Tad Williams' Otherland to any single person that has ever played videogame, played on the internet, or better yet--both at the same time. Awesome, awesome series.
My list:
1. David Eddings - Belgariad/Mallorean - favorite series ever. Deep, dark, humorous, and actually FUN to read.
2. GRRM - ASoIaF -- I hope he finishes this up.
3. Tad Williams - Otherland -- see above
4. Robert Jordan - WoT -- Really great, up through Crown of Swords. Progressively worse and formulaic since then.
5. Terry Goodkind - SoT -- A fun read, sometimes bordering on romance. Anybody that got as far as that crazy chicken with the wild eyes knows what I'm talking about. Good series but at some point it's like, "jesus, are you just throwing obstacles in their path to make this shit last longer?"
5. Phillip Pullman -- His Dark Materials (Golden Compass/Subtle Knife/Amber Spyglass) -- DO NOT OVERLOOK THESE because they're aimed at teens. Very good.
6. Harry Potter -- 'nuff said.
