First I want to say I did receive a copy of this book for free in order for me to provide a review. Having said that you can check my reviews to know I am honest regardless of a free book or not. In this case I am pleased to provide a VERY POSITIVE review. Now having received the second book and having not read the first in the series I decided to get the first book on my own so I would not be missing things by jumping into the middle of things. I was very happy to have enjoyed the first book of the series and was definitely looking forward book two. I am glad to say I was not disappointed. If you enjoyed oth UFseries such as the Dresden Files or the Alex Verus books then you will enjoy this series as well.
If I had to give a short description I would say Dresden mashed together with Gaimans Neverwhere.
