When I first started this book I jumped on my couch and dove right into it. I wasn't sure what to expect being that this is a different read for me, but knew I might still enjoy it. It rocked!What I liked most about this book is the story line. I have to admit that with the whole ghost element to it really grasped the reader. I dove right into Cas shoes, met Anna and became someone else. I love it when books do that for me. Ms. Blake writing is easy to read and so easy to fall into. You the reader, really get into book hunting down ghost with Cas.The other element in this book I liked is Cas as a ghost buster. (Oh no! Don't tell him I called him that. He doesn't like it! hehe) I liked the history of Cas's ghost hunting abilities and how he made a living off of it. Ms. Blake did a great job not only capturing the voice of a teenage ghost buster, but created a wonderful back round history to the story as well.That is other part of the book that really made the story, the history of Anna. Wow, I mean WOW! I was blown away by the harsh history Anna had and how is affected her in the afterlife. I cringed myself just thinking about. Ms. Blake really made the reader feel the emotions for Anna as well as Cas. I loved feeling Anna's anger and hurt but also her joy and sorrow when it was all over and done with.If you like a great ghost story with a different twist on it, read this book. I can tell you after reading this book I am amazed of how fast and how well I really enjoyed the book. Ms. Blake present you with a story that will haunt you forever!
