Well, it's a crime novel. It's in a slightly alternate reality that predates the current day. It's a very fast and good read, with a beautifully set-out world. I would not call it steampunk. I definitely would
call it noir.
(It made me sad I did not have a way to copy and paste stretches of text that were a page long and send them to some people I know who would really really like them.)
I am trying to think up a better review, and I will keep trying, but in the meantime I highly
recommend you read it.
