"Combating Cult Mind Control" by Steven Hassan
It is actually about his involvement with the Moonies, but it is textbook perfect for how JW's operate. JW's are the "poster child" for Cults.
I put off reading this for a few years when I first awakened, but when I finally did so, I WAS SHOCKED! It cannot be explained away by mere coincidence that JW's fit perfectly in the Cult mold.
