The Dungeon Anarchist's Cookbook

 The Dungeon Anarchist's Cookbook by Matt Dinniman, 544 pages.

The third book in the Dungeon Crawler Carl series takes us to the fourth floor, a very different type of dungeon level. This level is more puzzle than adventure game, with hundreds of train lines winding and twisting in an incomprehensible tangle. Luckily the crawlers, the last remnants of what was once humanity, have started unionizing. Huge networks of crawlers are getting connected, and it seems like together they may just survive this yet.

This was a slightly different type of book than the first two, but I think it did a really good job delving deeper into the themes of the series. I also don't think I've ever been more grateful for an author's note, which assured me before the book started that I didn't have to remember the many, many, many train line names and station numbers, thereby freeing me up to actually think about the story. I'm having a lot of fun with this series! I am currently impatiently waiting for book four to come in on hold.
