This is certainly an atmospheric story, and Lee has a writing style that's so descriptive you're almost transported there. The characters also leap off the page, Isa in particular. She has a particularly strong personality that you're hit with right from the beginning. 

Where I struggled with this book is the pacing. There's a lot of spooky, atmospheric elements, but it feels like it ends too quickly. A bit more resolution at the end would have helped the story breath, and give an overall more satisfying ending.

Be warned, there are also some pretty strong religious undertones in this, especially related to religious trauma. It's well done, but it is a pretty big aspect of the story.
