I enjoyed the first 50 pages and, after that, everything went downhill. I understand the author was trying to present a neurodivergent main character but that doesn’t mean the character had to be flat out dumb. I felt like the representation was almost demeaning to those who are neurodivergent. And her character and the plot was just wholly unbelievable. Except for the “whodunit.” Disappointingly, that was obvious. There wasn’t really a major twist or hook. I was disappointed, given all the hype with this book. 
But it should be noted; I don’t usually read mysteries so perhaps that bias has soured my enjoyment as well.
