The Long Way to a Small, Angry Planet (Wayfarers Book 1) by Becky Chambers [Kindle, $6.99]
This was an alternative family sci-fi story, like Firefly. Put a bunch of different personalities in a small ship and watch them bond. There’s some decent world building going on here, but not enough that I needed to look for Book 2.
There is a decent message here about accepting different cultures, sexualities, etc.
