The book is written for teenagers, therefore reads very easily. But it is interesting and really helpful for those who want to see themselves once if there are ghosts or not. The authors go with a healthy dose of skepticism ran on the matter, inform the readers that ghost hunting is mostly boring because you mainly waiting, waiting, waiting and very few events are really paranormal.
You give recommendations on what to wear at a determination (eg. As no jewelry, because it could reflect light), which electronic devices could be useful, how to lead preliminary talks with people who suspect a spirit with him in the house, etc. . Here it is not about to reinforce the idea that there are ghosts, but to develop a realistic view of seemingly paranormal events.
The book is entertaining and informative. Ideally suited for beginners.
