This book was so so good! Clearly the authors of this book did an extensive amount of research into cults for this book. I also would say I have a better than average knowledge base about cults, so I could really see and appreciate how accurate and detailed this book was. And this book was written so well and made me feel so stressed at times. It did such a good job of keeping the stakes so high. Especially when

Danny was trying to kidnap Roscoe.

And it was so compelling watching the various characters go through the deconstruction process and try to break out of the patterns of thought that cults enforce. 
And Ben was seriously terrifying and had pretty much every trait of the classic cult leader.
Honestly a lot of this book reminded me of the NXIVM cult. 2 years ago I read Don't Call It A Cult by Sarah Berman, and honestly I would be shocked if this book was not heavily inspired by that real life cult. Because they both have the base of being for self help and self improvement, and they both involved branding their members, and in both cases the cult leader has a woman as their second in command. This book was basically a fictionalized version of that real life cult.
But it was such an entertaining book and I would highly recommend it. 
Listened to on Libby.
