I downloaded this book as am audiobook on a whim when I saw it available on Libby because it seems like a short story with a fun premise. And I did enjoy the audiobook and finished it in one sitting. However, I do have to agree with some other reviews in which it was pointed out that this was not exactly a thriller but rather a family drama with a sister that just happened to be a serial killer.

I guess the fact that the story was pretty short and we only get the sisters point of view didn't make me care too much about the other characters (dead or alive).
