Not impressed with this book, however, I zipped through it in just a couple hours, it's easy to read because it's a plot done many times before so you can skim a lot of the pages, it take a twist at the end of 'who' was doing it but yet it isn't worth a 5* rating
Good mystery with some genuinely creepy parts. There were times I lost patience with the protagonist's dramatic reactions to things but overall a solid chilling read.
