This Census-Taker isn't what I was expecting (I didn't even read the blurb, so I had no idea what I was getting into) and it's quite different from Miéville's other books (though it's fair to say there's a lot of difference among his other books, so maybe this isn't a meaningful assessment). In any case, the mood of This Census-Taker is very dark and reminded me of several other books – most of all, it reminded me of Mercè Rodoreda's Death in Spring, which I had to put aside after I started it last year because it was simply too grim. I was afraid I wouldn't be able to manage This Census-Taker either, and probably if I hadn't had a long train ride with nothing better to do I would have moved through it much more slowly, and perhaps not finished. It is very dark. It's set in this kind of hazy place, disconnected from the outer world. The setting specifically is what reminded me of various other things I've read – there's a post-apocalyptic feeling to it, with just a touch of the supernatural, that felt somehow similar to The Memory Police, among other things.
I'm glad I did finish This Census-Taker. The end was satisfyingly ambiguous, leaving much still in mystery.
