I liked The Prefect and its sequel, which are also in there Revelation Space universe but take place during its heyday rather than in the post apocalypse. Chasm City is also a pretty incredible whodunnit/thriller. I liked that the Reynolds books tie together but also kind of stand alone, so you're not stuck reading them in order.
