 If you like urban fantasy and you haven't yet tried this series, do so. Now. The first book is Midnight Riot. Go find it. You'll thank me later. If you haven't read the first two in the series, don't read my review. It doesn't contain any spoilers for this book, but no promises about the previous two. 
 It's nearly Christmas, but Peter Grant, intrepid copper and trainee wizard, has been thrown into a case that is definitely lacking in holiday cheer. An American student has been murdered in the London Underground, stabbed in the back with the fragments of a magical ceramic pot, and mysterious figures have been glimpsed in the bowels of London. And that means Peter is going to have to divert his concentration from finding the identity of the evil wizard stalking the London streets to do a little urban caving in the underground and sewers. Soon enough, he's up to his knees in it--literally and figuratively. 
 ...And that's all I'm going to post here. 
 The rest of my (rather verbose) review is posted over here at Booklikes. 
 Why? Because I strongly disapprove of GoodReads' new policy of censorship.
