So, I can see why some people may feel like this book was trying to do too much, but I had a lot of fun with it. I didn't exactly go where I wanted it to go, even though I really thought I was right on a plot twist or too. I really enjoy books where you can see

the killer's point of view

, and the fact that this one still had some twists and turns was great for me. I also really enjoyed Hen's point of view, although I'm not sure how accurate of a depiction of bipolar is with it; Swanson also continues to do a decent job of a man writing a woman's view.

I definitely didn't see the fact that he didn't have a brother and it was a split personality at all, and I felt incredibly stupid for not realizing that she almost slept with and then got almost raped by one of his victims.

I really wanted to like this but I really did not. I’m a big fan of thrillers and I enjoyed the kind worth killing. however, I have never read a book that made me feel so sick. This book was  disturbing. 
the amount of misogyny, sexual violence was gross. The author stigmatizes DID and bipolar disorder.  The amount of sexual violence was beyond what was necessary and was described in great detail. The internal monologue of the killer was revolting. 

I listened to the audiobook which likely made that character’s internal thoughts about women even more disturbing. The way the killer talks about women was horrific. As a woman, the language was vile. It also made me uneasy that the person writing this was a man.  

The plot was not terrible but I felt sick from the sexual violence and the killer’s internal dialogue.

Also while the book is set in a fictional town, the author gives clues as to where it would be. He  says the town is on the south shore in Massachusetts, but the author’s descriptions of the town and the geography do not make sense. For example they go home from Logan airport but the author says they head towards Lexington to get home … on the south shore. The authors grasp on the geography of the region is sloppy, like most of the book.
