I'll admit, I got this book as a freebie from Adam the author (I'm from the UK and don't know him, so this isn't fake).
Who am I to turn down a free read and I have to say I really enjoyed this book. The lead character is interesting and the plot is captivating. It's urban fantasy without being too steeped weird side. As I said I thought this was a great introduction to the series and I'm eagerly awaiting the next one - Dec 2013.
I believe that any questions about Joe's (the main character) power could be answered in the coming books.
Read this if you like the Urban Fantasy genre, you wont be disappointed.
