I have read countless books, many by ex-JWs and some by Steve Hassan. But, the most helpful (and free) was the International Cultic Studies Association's online library of articles upon articles about cults, including Jehovah's Witnesses. They offer conferences and break out groups to help ex-members or family members of active cult followers. The Watchtower Society once told us to only read their books, and to not read anythng critical of them. Steve Hassan may be "simplified' but it's a good starting point for someone. Especially since he doesn't "harp" on the JWs (too much). Take someone who is just coming out and give them an ex-JW written book, and it they may just one screaming away, "Apostate"!
However, the first book I read was really good - it was "Awakening of a Jehovah's Witness" by Diane Wilson. I really liked her book. It was amazing that she and I had similar experiences.
Then, I read the 'Truth" book by Joy Castro. I really liked her book. It was amazing that she and I had similar experiences.
Why is there a common denominator? The BITE model as explained by Steve Hassan, which I didn't read until much later in my journey.
Now that I meet people who came out of other cults, we all lament on how the BITE model makes our experiences similar.
