I guess technically 3.5. The premise was definitely something I was exciting for with my macabre fascination of cults and such. But this really felt like for the first 80% of the book, nothing really happened. The main character wasn't interesting at all and I kept waiting for her big character arc that never really came. I wanted this to be much darker I suppose. I was waiting for the tipping point of "oh here we go..." of the sick thrill ride, but it was like riding a roller coaster that only goes the speed limit. The last half of the book was definitely better than the first, but I was also listening the audiobook so I felt like I just had to finish it. Had I been reading the physical copy, I likely would've sent it to the graveyard stack of books that are 20% finished.
