This is the ninth book in the series, and I highly recommend it for all urban fantasy fans! This was the first book I have read of this series, and I don't think you need to read them all in order to enjoy this one.
The author gives enough detail on most of the characters and a clear back story so that you know what is what without a problem. I loved Gin's character the most and would like to get to know Owen's character better. I will be reading more of this series.
