The fantasy aspects are primarily concerned with the original city running under and connecting all of the other cities in the world. This city was ruled by the Demiurge, who set up a great machine to hide the reality from the humans. Then, he left and the city has been rudderless for a while. The story deals with some of the consequences of this vacancy.
Now, this isn’t the fairest point to make, but the book felt very exposition heavy. I realize that there is a lot of crazy stuff to explain in this book, but this felt excessive. I noticed the omniscient text boxes, expository ally, soapboxing villain, and rambling, explain-y, crazy guy. The other issue I had was that our Mr. Zenk never seemed to be an independent agent. He was always buffeted by the plot and didn’t really direct it.
Ultimately, while I enjoyed this book, it was a bit uneven. If you are looking for some super dark urban fantasy, this might be worth a look.
