He's definitely good at what he does. It's a shame that I missed a chance to attend a book signing he did once. He was up in Portland, OR back when I was going to college there, but the actual date of the appearance was when I was home on semester break. It... sucked. I ended up leaving my copy of Vision of the Future with a friend who stayed in town and he ended up getting the book signed for me, but it wasn't quite the same.
As for the other non-SW stuff he's done, I've read a little of it. I've read his Conqueror's Trilogy which is a good military sci-fi yarn and I'm big on that sort of thing.
I'm... real big on that sort of thing. Heh. Currently I'm hooked on Karen Traviss. She's ridiculously fun. :D
