Becky Chambers' second book, A Closed and Common Orbit, is much, much better and does not have Kizzy or anyone like her in it. It's probably worth trying despite having bounced off the first.

(She has a third that I haven't read yet, though I want to--I'm saving it for a unicorn chaser once I finally manage to read Rivers Solomon's An Unkindness of Ghosts. Maybe I should just read it now, since I don't know when I'm going to have the spoons for the Solomon.)
