I'm having a hard time reviewing a part 1. I enjoyed this story but I am a sucker for a serial killer romance. I can't wait to see where this one goes. I Love to Hate Mara I love that she is so spunky and defiant but still somehow makes awful decisions. 
Love the back and forth POV. I love the illustrations. I have never cared about a Playlist in a book before but I like the way it was incorporated into the story but I personally find music in the background distracting
