Book 45: Those Beyond the Wall. I could not remember as much of the previous book as I'd thought but that was fine. This is a "some years later" version of the same world with much less multiversing and much more (by the author's own admission) rage. It's a poetic look at intense inequality as seen through the eyes of those who have less, as they interact (or remember, or try to make deals with) those who are more privileged and who have, perhaps, even less of a code of honor.
