This urban fantasy is a love letter to London. The writing is clever and fun. I didn’t get ALL the geographical references and I wish there had been more attention paid to the rivers storyline but I enjoyed it enough that I’d absolutely read more in this series. Side note: I had this book on my wishlist for awhile, but as the UK version, which is called Rivers of London, so I didn’t even realize this was the same book at first when I spotted it at a bookshop on Cape Cod last summer.
