I picked up Moon over Soho in a recent library haul. Its the second in a series of books called Rivers of London, the first of which I read ages ago, so I've been meaning to read this for a while. I was initially attracted to the series thanks to the intriguing quote on the front cover, "what would happen is Harry Potter grew up and joined the fuzz".
The Plot: Peter Grant, met officer and trainee wizard, investigates the suspicious deaths of Jazz musicians in Soho.
My thoughts and views are under the cut (warning may contain spoilers):-
