I heard either a summary of it or someone talking about it on a podcast and it sounded interesting. A friend who was never a JW read and liked it. I have no clue why you think someone that was never a JW wouldn't be helped by it though. There are more issues in life than just ours.
If you want it, buy it. It's $15. If you get just one nugget that impacts your life positively then it's a heck of a lot cheaper than a therapist.
