I loved this book so much I am going to read the next book as soon as possible. I really loved the characters especially Cas he is one of the best male MC's that I have read from POV of in awhile he seemed like what he was supposed to be a very well written male character. I also really liked Anna she was the reluctant killer of many people a ghost who does not want to kill people at all. I really liked her as a love interest I have never read a book where the love interest is a ghost she is determined and willful I found her very interesting to read about. The other characters are very interesting to read about as well there are so many well written characters from Thomas to Cas's Mom. I really liked the plot it started out with Cas hunting a ghost and quickly moved on to finding Anna to kill her and so much more this was one of the best ghost stories I have ever read. So overall I loved this book I will read the next book soon.
