It's amazing what a difference a few years and exposure to actual literature makes. While I still hold a dear place in my heart for D&D novels (and Battletech and Star Trek, while I'm at it), . . . well, maybe he's just slipping, but I picked up The Thousand Orcs, and was reading through it at my local book store, and I got to page 2 before I started to mutter to the pages, "Get on with it." Lots of activity fleshing out characters who end up dying meaninglessly, and slow to boot.
Admittedly, I didn't give the rest of the book a chance after that, but my gut tells me it wouldn't be as gratifying as some of the works I've had to read for my English degree.
I wonder if I'll ever get around to rereading my old books. I know that when I recall the plots they feel very cool and interesting, but I'll have to take another look at the craftmanship. Also, why can't people seem to write stories in just one book? All these trilogies!
While we're on the topic of good novels, though, I will say that my favorite in my memory is the brother's trilogy (officially the Legends Trilogy) in Dragonlance. Rather than covering a huge cast, it focused on three characters, and had a scope that was brilliantly both epic and humble.
