Ah, time for research.
I read CJ Cherryh's
Downbelow Station over the weekend. Pretty good space opera with a fairly hard sci-fi background, although my personal quibbles with Cherryh's writing style kept me from fully enjoying it.
I always have a hard time piecing together what is actually happened in the setup to her novels (see spoiler), and character motivation always feels fuzzy (see spoiler).
Solid 7/10 book though. Plenty of good page-turning action, high politics, and space opera in a crunchy hard sci-fi shell. Might try and track down her other books in the Alliance-Union series.
C.J. Cherryh has a writing style that is unique to the point that you either like it or you don't. There's a rhythm to it that gives the reader a sense of the calmness or the anxiety that permeates a scene or situation, or how a character will react.
She's done a tremendous job of worldbuilding, whether the "world" is a star station, a merchanter ship, a spook ship, warship, the community of Reseune on the planet Cyteen, the creepy world of Gehenna, and so on. When it comes to plausible science, she does her homework.
When it comes to this particular novel... Downbelow Station was the first Cherryh novel I read, back in the early '80s, when she was the Guest of Honor at the science fiction convention I attended that year. It's special to me in that it's the first time I met a real science fiction author, had a chance to say a few words, and get a book autographed. Cherryh is someone who has a vast array of interests, and her attention to detail is beyond amazing.
The Alliance-Union setting is complex and detailed in that it feels like a
place - somewhere that could plausibly exist.
Signy Mallory is a heroic character to a lot of fans, as there's none of the nonsense of "Ohmy, the captain is a
woman" and a lot of sexist BS follows. She's got her own set of ideas of what's right and wrong, her own morality, and when the Fleet crossed the line of what she considered right and moral and workable, she refused to go along with it.
In this setting, the captain of a ship - fleet ship, merchanter, etc. tends to enjoy a great deal of respect and loyalty from the crew.
There's a classic filk song about Signy Mallory. This version is sung by Julia Ecklar:
I think I posted a list of the Alliance-Union novels I enjoy most, somewhere in this thread.
IIRC Downbelow Station is one of a series of books about that particular "universe". I have liked most of her Sci Fi stories and the various world building she engaged in. It has been quite a number of years since I read her books though.
Time to read them again, then.

There's a new one coming out next year (I was beyond annoyed to find it wasn't coming out this year, and the release date was 2024... a whole 'nother year... not fair!
