The Shining Girls started off kind of rocky, got better, then falls apart. It takes a little bit to understand what is going on with Harper because the book explains it in a vague sentence early on. He goes back in time and kills women because the house he is in tells him to. Yep. A lot going on that just gets messy. The characters are great though so that makes the book more interesting and able to stand the time traveling serial killer scenario. The book just goes to hell at the end when Kirby kind of figures out what is going on. No real reaction just a need to stop him. Ok. And what happens when she does stop him? The book ends. I was really hoping Kirby and Dan would try to explain it and prove what Harper was, but nah.
