Query: A Great Start for Learning Mediumship

I've read countless books but this one really hit home. Not only does he go over his struggles with mediumship, he shows you how to do it. John Holland is an excellent writer and I have found him very compelling. He doesn't seem to be in it for the money or the fame, it just seems to be a part of who he is. I feel he is very credible and I think it's an amazing book.
