I've just finished reading Alan miller's "fade from the truth", I enjoyed it and I love that it's freely available.
First, a big thanks for reading that. I will say a few things about "FADE" and maybe it will help you with your desire to write. I didn't make it available to get rich, I would have needed to keep my day job no matter what.
I read Kyria Abraham's I'M PERFECT, YOU'RE DOOMED while I was writing a horrible and bitter book about my thoughts on JW doctrine. I knew it was such a negative work that I had to abandon it. I didn't even want to read it, certainly nobody else would. I was very much inspired by Kyria and her way of simply stating her story.
I was going through therapy and started just telling my personal story for my own personal therapy. I actually started with a profound event in my life (a suicide attempt) that led to me becoming a JW as an adult, then needed to back up to my childhood introduction to JW's via my mother. Then it only seemed natural as I processed the outcome for therapy to write out the outcome of my journey.
Along the way, I debated with myself about making that personal story into a public story. I finally decided that if I could help a single person on their journey, it should be public. I googled some things about how long a book should be and got the Zen answer that it should be no longer than needed to complete the story. But I also learned that a published work should be close to a minimum 50,000 words. My story was shorter than that and seemed to accomplish the Zen goal, but to get to that minimum, I added a short chapter called ANAMORPHOSIS which was my meditations that came from an epiphany on how I, at a low point in life, needed to believe in the illusions created by Watchtower.
I shared my story with Barb Anderson and she posted it to her webpage. Later, I put it on Amazon as a very low priced ebook and as a print book. I have met a few people who say it has made a difference in their lives, which is way more precious to me than any profits. I think every writer of JW stories can tell you it's not the way to get rich.
I hope that helped.
