You may ask what the book "validates that some of us have been talking about for so long." At the top of my list would be VPW's misogony, his vindictive attitude towards Christian denominations, and outrageous claims and opinions about what God does and doesn't do. He tells that story about when he heard God tell him audibly that He'd teach him The Word like it hasn't been known since the first century if he would teach it to others. And the phony snow story ensues.
Anyway, for some people, they may be wasting their money to buy the book (at this time you preorder it on their form, which lacks a field for your street address, so you have to put that in the same box as the state). For others, it might be worth it to get the book and see for themselve VP the conman who double-talks his way through answering questions Whiteside puts to him. Elena was a nice lady but totally starry-eyed like the rest of us back then. She interviewed me and many others at HQ back then and shaped the material into a propaganda story.
I could be wrong, but I don't think there's anyone in the book that's still involved with the original Way organization. They're either running Way offshoots, or, like me, have rejected any connection with VPW teachings or fellowships. Some who are featured in the book have passed away, like Del Duncan, Ian (Doug) Murphy, and George and Bernita Jess.
