I think this book was less for me than I initially thought it would be. I was excited by the idea of a thriller set at a k-pop survival show, but the actual plot was more like a bootcamp, not televised, and the structure of the training program quickly got sidelined by the supernatural events and the horror elements. 

That whole plotline made sense to me, especially the sapphic final girl vibe we get from the halfway point onwards. It just wasn't the element of the book that actually interested me, so as these elements took more and more prominence I was less and less engaged. Actually, it's not that the book wasn't engaging, because it was really gripping and fast-paced from start to finish; it's more that I didn't feel emotionally invested, because I am way more interested in the realistic fucked-up problems with kpop survival shows (cameras, fan voting, etc) than in the supernatural elements the book added. But I can see this working well for someone who is into commentary on beauty culture using body horror elements. 

I also enjoyed the rivalry and tension between the two main characters (the narrator and Candie), it felt very true to how fraught teen friendships between women can be. And the influence of The Craft on the book was very clear and fun as well!
