Terminal World

This is the type of story that makes you wish it was in a series, just so some of the fantastic world building can be re-used, but it would dilute the magic, and so you are glad that the author is content to leave well-enough alone.

This is sort of steam/cyber-punk sci-fi. Sort of if the Red/Green/Blue Mars series crossed feelers with Vendermeer's Finch. With less mushrooms.
