I first came across this book in Aachen, Germany, and it drew my attention almost immediately. Normally I'm not really a fantasy reader, let alone the even more specific terms like urban fantasy. I liked the writing style from what I read in the bookshop, and made a mental note of it.
Still, in the Netherlands this book is nowhere to be found. (It isn't translated either, for as far as I know) (I first wrote this review in July 2012, as it is one year later now, I still haven't encountered this book in either The Netherlands or Belgium...)
I did really want to read this book, so next time I bought it, even though I had decided not to buy any books for the time being.
I started reading, this time proper, not standing in a bookstore and I liked the book. Perhaps I thought there were things I didn't find as interesting - like for example all the stuff about the rivaling rivers (OK, what's in a name?) but I liked the setup with Scotland Yard and the Folly.
