Timothy Zahn

He's written many books, including some ever popular Star Wars books, if you're into that sort of thing. (I'm not really, but his were still good)

I particularly recommend "Spinneret", "Cascade Point and Other Stories" and "Cobra", though I haven't read anything by him I didn't like.

Oh, and don't plan on just reading the first book in the Conquerors' series.
