So, this book actually made me leave The Satanic Temple! Probably not what you wanted to hear. 

I found that I was all on board for about the first half of this book. Then, I started questioning things that is information that isn't necessarily discussed on their website. Firstly, they are very anti-supernatural. At the same time, they do rituals and are okay with you being spiritual (yes, I know they aren't one in the same, but there is too much overlap for me to feel comfortable about it). Then, they call letting people know you're a Satanist as coming out, which of course is usually termed for when a person who is part of the LGBTQIA+ community decides to let people know who they are. The more it came up, the more it rubbed me the wrong way. I also didn't like how so much was quoted by the founder of the religion (it kind of gave me cult, but without a deity vibes). They also have a Grey Faction which is supposed to dispel harmful pseudo-psychology practices, which they lump DID in with. It's never fully explained if they think DID is an actual disorder or something that goes in line with memory gaining psychotherapy (DID is a very real disorder btw). I also found it rubbed me the wrong way that to join a local chapter or group you need to become a member. Now, that isn't unheard of, but I haven't heard of other religions needing a screening and interview process in order to attend functions.

This book made me realize that maybe the contradictions and they gray space was just too much for me. I just don't have enough faith (you still need that to some capacity in a non-theistic religion)!

What I will say is that if you want to learn about TST or just some cool readings that are referenced, I do recommend this book. It is very indepth into what TST is and what it's not, it's history, etc. It just made me realize that maybe TST isn't my thing.
