First a disclaimer: at this point I think a Becky Chambers book would have to be pretty terrible to get a bad review from me.
This is very clearly a novella, and continues Chamber's trend away from plot driven fiction as seen in the later Wayfarer books. So, not much happens, but deep themes are explored.
The solarpunk aspect has been remarked elsewhere, but I didn't expect was how much it seemed like a reflection on the (privileged) human condition. As a fellow privileged human, I recognized some of Sibling Dex's disquiet.
