Pros
+ The audiobook narration was fine?

Cons (there are more but I'll just go in-depth with a few)
- None of the characters were particularly compelling. Margot was extremely bland. Krissy had such weak characterization, presumably so the author could have Krissy do anything and expect the reader to accept it. Billy was just confusing.

In the last chapter, he intends to hurt or maybe kill Krissy but accidentally throws his daughter, January, down the stairs. When January says that he hurt her, he gets very mad at her and kills her. Is this supposed to indicate that he has extreme anger issues that apparently don't manifest in any other area of his life ever? Or is it supposed to say that he has a personality disorder that makes him unable to take accountability for anything? We don't know because we literally have no idea who Billy is as a person.

- The non-ending. Is this some sort of attempt to differentiate this book from other mystery/thrillers? The entire book is Margot chasing leads, talking to people about January or Natalie, or dealing with her uncle, Luke. The whole purpose of that is to build up to an exciting finale/resolution. But then we're left hanging. The only other piece of exciting action

Elliot Wallace's arrest

is told to Margot after the fact. 
- Luke Davies.

Firstly, the Luke is Dave plot twist was extremely obvious because we spend too many pages with Luke for him to not be majorly connected to January. But also, we spend too many pages with Luke anyways. Margot is always feeling guilty about leaving Luke alone, Luke is forgetting something, Luke is having an "episode," Luke Luke Luke. Finally, how did Luke not connect the fact that right after he told Billy that he wasn't January and Jace's biological father, January is murdered? Are we supposed to believe that he would let January's murderer get away just to protect the secret of their paternity?
