I really dont get into the spirtual side of things, so no books to recommend on that note. However I am reading a book about the twa800 flight that crashed over in long Island in 1996. Called "Night fall." Very good book and has some crazy twists and gets you into the fbi/Cia side of things. Very interesting.
Another Book I read that kind of ends shady, but was very good is called "hosts" Is about a cult trying to get a mass amount of people to take over other certain bigger organizations. Repairman Jack is da shiznit!
Ok that is all I have for now.
