This book is so deranged and I loved it - disturbing body horror, edge of your seat 'reveals', and I was truly disgusted and flinched or had other physical reactions to so much of it. 
 
However, I did feel the relationship between Isaac and Lauren was kinda gross (and not in a good way). Isaac read WAY older to me than 22/23, most of the time I thought of him as middle aged, so the relationship felt weird. Also, throughout the book there are multiple mentions of Lauren still being in high school (even if she is a year older than everyone else, which somehow almost feels weirder? - just have her as one of the Uni students?) and how barely legal she is. It gives fetishy and cradle snatcher vibes. I'm pretty convinced that Isaac was a self-insert for the author in this relationship.   
 
I also thought the ending was pretty lacklustre compared to the drama of the rest of the book. 
 
However, still a great book, and I will definitely continue reading Payne's work.
