I loved it, I was on the edge of my seat! I had wondered how Green would top his last book... Fear not! John Taylor gets to play with the good guys! Mostly, anyway. 
 When Exacalibur shows up on John and Shotgun Suzie's door, it can only mean destiny is at work. To which Suzie sums up with a succinct curse or two. And John gets to travel to real-world London to talk to the stuffy London Knights, among others. Don't think that just because they're playing with the "good guys", that John and Suzie don't get to cause great collateral damage. Because they spread much death and raise insurance rates wherever they go. 
 There were a lot of action sequences, and a feeling of light-hearted humor, in spite of the serious problems. Because when doesn't Nightside have serious problems? Or is a serious problem. I am SO looking forward to the next one!
