Many years ago, I wrote the book, " parasite Zapping and the Zapper" but as time has progressed, I have found a number of things that needed to be added or updated. It has finally gone to publication and is expected to be available in about 2 weeks. It has increased from 80 pages to about 130 pages and has additional topics such as a short history of electric healing.
