A few days ago I finished Heavy Time by C.J. Cherryh.

It's set in the same universe as Rimrunners, but in a very different time and place. This one is set in our solar system and involves miners working on asteroids. It starts with a distress call that two miners answer hoping for salvage and instead find one person still alive. That person is very damaged - not only physically, but mentally out of whack after having spent months trying to survive. The rest of the book follows the miners as they return to base, try to claim there salvage, and deal with the oppressive company that runs the mining operations and has secrets to protect.

It was more enjoyable than Rimrunners, though the point of view of the disturbed character gets old after a while. He slowly recovers, but the emphasis is on slowly.

Cherryh's approach is interesting, because she keeps things at a very low level and therefore her plots are more intimate and cover less ground than many SF works. I will probably keep reading these books, since they make good stand alone SF novels as well as contributing to a nicely varied and deep background universe.
