Since I am a fan of Ghost Hunters, I thought I would read Zak's book Dark World. Zak along with two other members of his team,wants to share with you the experiences he has had investigating paranormal activities and unexplained phenomena. Whether you believe in the afterlife or not, he does his best to find and share answers to what people encounter. Since he has had personal experiences of his own, he is very dedicated to his work. An interesting read.
