This horror novel was different than any other horror novel I have read and I found it surprisingly refreshing. William Saint is dying from cancer and is brought to Mercy Hospital against his wishes. There he finds not only is he is dealing with demons from his past but a very real horror that has changed the medical staff and the hospital itself. Now William is fighting not only the visions from his past but a very real evil that wants to use him to gain access to our world. I really liked this novel. I found it to be very different from anything I have read before and also very unsettling at times. All in all, I didn't want to put the book down (but had to as I do have a non book life lol) and didn't want the story to end. It is very well written, informative, and the author also has a talent with keeping a growing sense of unease and suspense. Highly recommended.
