The Galaxy and the Ground Within

The Galaxy and the Ground Within, Becky Chambers. Fourth and theoretically final book in the Wayfarers series (she talks about "ending a series" in the acknowledgments, although I would not be surprised if she decided to go play in this universe again in ten or fifteen years or whatever (and I wouldn't even roll my eyes about that, unlike some authorial revisiting)). I liked it a lot, and without the reservations I had about the previous one (that post here). This is a very tight-focus book, with five characters, one location, and a narrow span of time, and it works really well, delivering some characteristic poignant moments and nice little bits of worldbuilding and aliens being alien in neat ways. I think it would read just fine as a standalone, or as a followup to the first book if you haven't read 2 and 3.
