I have read several of Jims books and they are always controvercial, but objective. I excpected his "PSI spies" to be just that - and it was.
This book is not a brick, but it's still filled with sourced information. The subject (remote viewing) seems to be difficult to get to the bottom of, but Marrs have gone out of his way to do just that.
I think Jim Marrs have taken "investigative journalism" to the next level - and beyond - with this book. Most impressive are the facts that he reports on others doing RV sessions with him present and that he even joins in and experiments.
The books subjects are neatly tied thogether with great writing for easy consumption in a typical Jim Marrs style.
