The dazzle of day

Molly Gloss knows what she is doing. She takes a handful of elements - Quakers, the environmental crisis, interstellar travel - and forges an authentic world with just a few pages.
The fruit is a book for readers looking for deeply thoughtful character study and a certain amount of philosophy.
It is not for the seeker of space based science fiction challenge. Warning to readers: death both current and remembered of children and adults; also marital rape.
The world is well thought out and three dimensional, the prose rhythmic and immediate, and at the end of the day just not for me.
The characters are introspective to the point of being unlikable. The action of the story mostly takes place offscreen while the actual focus of the tale is the mundane and sometimes off putting inner worlds of the rotating POV characters. There is also a rape scene between a married couple which was treated more like a faux pas than a crime. All in all, I was left feeling like I had dipped my thoughts in slime after coming up from the story.
But it may be exactly what you are looking for! The unpleasant aspects are not prurient or pornographic, and serve the overall message of the book.
Just not for me.
