This book claims on the cover to have been edited by David Drake and Bill Fawcett, but there are some glaring problems with the shared world editing should have fixed.
First, the stories are generally quite good. They range from old-school space opera to character studies to a detective story, with a space-opera feel. You really get the atmosphere of a good World War II movie around the people on board the station. There's no slick cynicism, and on the flip side, there isn't any gung-ho jingoism. The bad guys are bad, although they have their reasons, and the good guys are good, except for war profiteers.
The book supplies brief interstitial pages to explain how each story fits into the overall narrative, and these are very effective. The overall arc moves along, even if the individual story isn't pushing it.
Now here are the problems: simple aspects of the shared world vary from story to story. The early stories make a big deal about how slow the FTL drives of the core aliens are. In one, the core refugees took 4 months to make it to Alliance space in the spiral arm. Alliance characters snort and note they could make it in weeks.
But in later stories, transit times go higher than 4 months. It takes reinforcements 7 months to get from the Alliance to the mobile base that's at the center of the story. ??
Also, one story notes the base is at the end of a supply line 200,000 light years long. That's quite a trick in a galaxy approximately 100,000 ly across, when our solar system, in Alliance space, is about 25,000 ly from the core.
And the whole point of the mobile base was that it would be its own supply line, manufacturing its own supplies and ships.
These errors took me out of the suspension of disbelief and reduced my enjoyment of these stories.
