I finished the book a couple of weeks ago, and I have to say, it really is very good.
One of the questions I get asked most is, how did you get suckered into joining a cult? And I think Charlene answers that question by showing how incremental the process is.
I found the story to be a deeply personal one (unlike The Cult That Snapped, which was "about the Way," Undertow is about the author).
Beautifully done, Charlene. Congrats!
