Paige Mahoney has finally managed to escape the prison camp of Sheol I. One would think that she could finally breathe easy. But her problems seem to have just begun as she is now the most wanted person in the whole of London and its underworld. In the meantime, the world is preparing for a rare meeting of the Unnatural Assembly where the mime lords and queens are invited and the Rephaims finally make their presence known. Yet there are secrets that are yet to be revealed and secret propagandas at work. With a target on her head, how will Paige fare in this new world? 
 Like I mentioned in my review of The Bone Season, the world building in this book takes up a major chunk of the pages. It continues to do so in this book too. We find out a lot about the Underworld and the way they work in this book. Jaxon and his Seven Seals are exposed more fully as we find out more and more about what makes them tick. Then there are the Rephaims... Their history is also revealed, though I get a feeling that we may find out more in the coming books. There is a lot of action going on in this book. Dead bodies falling like flies and Paige with a target on her head, things boil up to a point where I almost wished for a huge explosion. That explosion never came, though the story continues to build up. 
 I love Paige, I really do. But she really annoyed me at times in this book with the way she goes on and on with her planning and rehashing those plans. She did act on them, but the ratio of her planning time and actual action time had a huge difference. I feel that the book could have been a much shorter one if only the author had kept Paige in control. Anyways, end of the day she does kick some serious butt and so she remains my favourite. I also liked how the romance in the book was handled. It was there, but it did not take away the spotlight from the more important aspects of the book, though it wouldn't have hurt to give us some more Warden time. 
 This book too has a slow start like its predecessor, but it is again because the author had to layout some of the basics of this new world. Once you get over the initial slump, the story gets going and turns into a total page turner.
