I love stories about the underbelly of London--not a criminal underbelly but the weird side, the supernatural side, the dark and hidden secret things and places that exist parallel our known world. (I would love stories about the underbellies of other cities too, but somehow it's usually London.) This one is very reminiscent of MiƩville, though a little less weird and with its own distinctive voice (in some places more than others).There's something about it that didn't quite sweep me along, and I didn't always buy the character interactions, but at the same time there were a lot of compelling moments and I was really captured by the ending. So definitely a win overall.
