Ben Aaronovitch, Midnight Riot

Ben Aaronovitch's Midnight Riot is tremendous fun, smart, witty, amusing, compelling and interesting.  A rookie cop in London accidentally finds himself apprenticed to the single surviving member of an ancient society of wizards who work to keep the peace among the supernatural elements still active throughout the city.  Sounds deeply improbably, and of course it is, but Aaronovitch carries it off lightly, and our everyman hero Peter voices our skepticism for us, despite all that he encounters.

Aaronovitch wrote for the BBC's popular Dr. Who series (delightful, at least until the entrance of the 11th Doctor), and the tone will be familiar to fans of the Doctor.  Also for those who have spent time in London, there is the added entertainment of reading of supernatural happenings in familiar haunts.  Give it a go.  I've got the sequel on my wishlist...
