This is extremely good, not just a horror book but terror book.  The entire time you are anticipating the terror of what’s next, overall such a well written book.  The premise itself is not overly unique but the writing, characters and tone of this book set it apart from others.  It’s very readable but also gripping you want to know what’s going to happen but you really don’t cause you know it’s going to get worse.  100% recommend.
