I read this book in about six hours. I could not put it down once I started. Zak knows what he is talking about and as a big fan of the show I really enjoyed all of the stories he put in it. Zak also shows off a more serious side of himself in the book which I really like and he talked a lot about the science and future of paranormal investigation which really made me see him in a different light. There are some errors and some issues the editor did not fix that I caught in this book while reading but overall I really enjoyed this book and can't wait to see what Zak does in the future.
