Im in that camp, I know, I really wish this had been marketed as a YA because of the style of writing. The Content is often graphic and there’s a lot of cursing, but to say that this is an adult book Purely based on the content I think is unfair. 
There were a number of parts that got me. I was often on the edge of immersion and the inconsistency of the   dialogue pulled me back out. 
I really really really wish I liked this book more. genuinely and whole heartedly I do. But it didn’t hit.
