I was really surprised by how much I enjoyed this book. I love Schaefer's Daniel Faust series but am not so keen on the Harmony Black books so I was prepared for the possibility that it wasn't going to grab me.
What I wasn't prepared for was that I literally didn't want to put the book down, so I stayed up all through the night and read the book in one go. The main protagonists (no spoilers) moved me, I even ended up caring for quite a few of the minor characters.
This book does fit into the Daniel Faust and Harmony Black plots but you can read it quite independently, I think. On the other hand, why do that when you could have hours of good reading ahead of you?
So, if you like dark urban adult fantasy get this book. If you like Schaefer's other books then get this book and be ready to not put it down until you have finished.
