The ending really saved this book for me. I was super excited to read this book and find out more about sibbys origins but it was kind of lack luster. It failed to deliver the full back story. It was like crumbs of a back story that were super interesting. I wish we got more of her growing up and escaping the cult. Then just a barrage of murder and sex that was repetitive and a little boring. Then one chapter of her in the mental hospital that was actually interesting and I wish we would have gotten more of.  The last chapter and the flash backs are what saved the book and got me to give it the score I did.
