City of Ruin

The sequel to Nights of Villjamur. The action has moved to another train wreck of a city, where things are just as bad, if not worse. The worldbuilding continues top-notch, and the plot rolls on, horrifying and fascinating. This reminds me a lot of the Shadows of the Apt series, where things are just going terribly all the time, but you're so engrossed in the characters and the world that you just can't stop reading.
