My latest kindle check-out from the library is Downbelow Station: The Company Wars by C. J. Cherryh. I had read it long ago and always wanted to try it again. Here's a bit about it from Wikipedia ...
Downbelow Station is a science fiction novel written by C. J. Cherryh and published in 1981 by DAW Books. It won the Hugo Award in 1982, was shortlisted for a Locus Award that same year, and was named by Locus magazine as one of the top 50 science fiction novels of all time in 1987.
The book is set in Cherryh's Alliance-Union universe during the Company Wars period, specifically late 2352 and early 2353. The book details events centering on a space station in orbit around Pell's World (also known as "Downbelow") in the Tau Ceti star system. The station serves as the transit point for ships moving between the Earth and Union sectors of the galaxy.
