Moon over Soho by Ben Aaronovitch is the sequel to Rivers of London or Midnight Riot, depending on which side of the Atlantic you are on. Peter Grant, the street copper turned wizard's apprentice copper, is dealing with the aftermath of his first adventure, when a new series of deaths is brought to his attention. Apparently jazz musicians keep dying, and he senses a touch of magic on the corpses. But why would jazz musicians die after performing? In order to solve this case, Peter involves his dad, the former junkie who plays jazz music, and gets involved with the girlfriend of one of the dead guys. The book introduces a recurring villain who has it in for Peter and his boss Detective Nightingale. - I loved the first book, but felt it lost momentum and tension in the later parts. Not so with this book. I love the super-dry British humor. I can connect a lot better with the British Peter Grant than the so-American Harry Dresden. It was funny, witty and exciting, sometimes creepy to read. Even if it dealt with jazz vampires, which sounds ridiculously silly. Or female assassins who chop off dicks with their vaginas. I want more.
