I'm sure his other books are good, too, but this is the only one I've read. I've never seen anyone else able to extrapolate the consequences of entire races advancing past the Singularity and how mortals manage to get by in such a galaxy (if you're able to accept faster-than-light travel as a premise, but he has a very interesting take on even that). A ton of innovative sci-fi ideas in one novel.
