The first half of this book had me hooked. It had so many elements that I love in a book. The writing was eerie and deliciously readable. The premise of girls turning to rust and decay without any good explanation was absolutely riveting...at first. Unfortunately, the second half left me disappointed. It just didn't really go anywhere. I thought for sure from the first half of the read that it would be a 4 or 5 star book and I was disappointed in the second half but not enough to dislike the book entirely.
