Yeah, I figured you were pretty well-read, and why am I not surprised that I have heard of virtually none of those authors?
I don't read a lot of sci fi or fantasy, but I did enjoy Ender's Game and The Hobbit!
I also like a lot of classic novels. I read Watership Down for the first time a few years ago, and it is now one of my favorites. I've loved Lord of the Flies since high school. I even bought Moby Dick a few years back, but I was kidding myself.
One book I really liked is called Hothouse by Brian Aldiss. Haven't been able to find it in hardcover, though.
