Hmm, at times equally creepy, disturbing, haunting and yet thoroughly enjoyable, this book captured my interest from the first page and didn't lose it until the last. Quite suspenseful, and surprising to boot. How often do you find that combination? The protagonist being a book-loving, self-contained woman only helped the story, in my opinion.
As far as the cons go, I would say it was a bit drawn-out at times and certain situations seemed to be a little too coincidental. I wouldn't say those aspects particularly disturbed me, though.
Overall, a somewhat darkly entertaining book.
