Honestly, a little woo-woo? Too many instances of "after one session, problem solved" -- not sure if that's how human beings work, especially when it comes to significant generational trauma. 

But, despite that, informative and will definitely cause the reader to broaden their contexts when thinking about their life. It certainly poses an interesting possibility of why we are the way we are (at times, in ways we can't explain).

Still, I think it could've been a longform essay or a workbook instead of a non-fiction novel.
