City Infernal Books in Order

City Infernal takes the oldest horror setting there is and rebuilds it as a modern city. In these books, Hell is not a fiery hole in the ground. It is a sprawling metropolis, sometimes called Mephistopolis, full of towers, traffic, neighborhoods, systems, and rules. The damned do not just suffer there. They live there, or try to, inside an endless civic machine built on pain.

The first book gives the series its emotional hook. Cassie heads into Hell to find her twin sister Lissa after Lissa's suicide, and that rescue mission gives the reader a guide through Lee's version of the afterlife. The city is grotesque and absurd, but it is also mapped, crowded, and oddly practical. That is part of the fun. Lee treats damnation like urban planning.

It is a rescue story, but it is also a travel story.

Later books widen the canvas. Cassie keeps colliding with Lucifer's plans, fallen angels, strange allies, and the awful logic that keeps Hell running. By Lucifer's Lottery, the focus expands again, with a theology student taking a guided trip through the abyss by none other than the damned soul of H. P. Lovecraft. The setting is strong enough to hold both personal grief and cosmic nonsense at the same time.

That mix is the real appeal of the series. These books are nasty, but they are not just nasty. They are imaginative in a very specific Lee way, half nightmare, half dirty joke, half theological fever dream. The violence is extreme, the sex is grotesque, and the worldbuilding is surprisingly sturdy underneath all the slime.

If you want a clean, solemn vision of Hell, this is not that. If you want an afterlife built like a corrupt city, with family grief, demonic politics, and a lot of bad decisions, this is where Lee really lets loose.
