This is a story of familiar outline, and it does a satisfactory job of it. Unfortunately the London urban-fantasy scene has a lot of competition these days, and this book doesn't do a whole lot to stand out. The use of the (too weird to be fictional) Quit Rents ceremony of London is a nice touch. The use of the "climactic legal challenge that all Fey are bound to" trope is a tediously cliched touch. In between are Niall's relationship with his ex-wife, his daughter, and the romance subplot -- those are decently done. The author is deft with secondary characters; in fact, I think I liked most of them more than the protagonists. So, a mixed recommendation.
