Anyone read Kate Griffin's Matthew Swift novels? 'A Madness of Angels' 'The Midnight Mayor' and 'The Neon Court'. The latest one is 'The Minority Council' which I'm just finishing. They're a brilliant read.
Matthew Swift is an 'urban magician' drawing power from the lights, fumes, history and cityscape of London. The books are full of fantastical but entirely believable characters.
Old Father Thames is real, magical power sings through the telephone lines, the dragon emblems of the City of London come into being to protect the city when needed...and sometimes, being dead doesn't mean you can't come back!
