A co-worker asked me recently for a list of science fiction books I'd recommend. I haven't been reading as much science fiction in the last five years as I used to, but that's partly because my success rate at finding stuff I liked dropped off a bit. If my list of favorites signficantly overlaps yours, please comment and let me know what I'm missing.
I'll follow up with a separate fantasy post sometime soon. It will have some author overlap, but this list was long enough already. My favorites are starred.
