Like the other Wayfarers installments, The Galaxy and the Ground Within (Wayfarers 4) seems to answer a specific question: how would different sentient species need to interact to not be in constant war? While other science fiction novels seem to start with the tech and fill in the social blanks later, #BeckyChambers seems to consider them first. The first three installments of Wayfarers dove deep into the relationships between characters of different species and gender within one crew. Wayfarers 4 took that same concept and isolated characters in a space bed and breakfast. Again, Chambers wove characters and their development together wonderfully. I just can't recommend Wayfarers 4 or the other three enough.
