I have read Graham Masterton for years, he is the best horror writer ever. He hasn't lost his touch, this book is so good, my eyes couldn't get across the pages fast enough to get to the end.
If you love horror, get any of Graham's books. I used to love Stephen King, but once I discovered Graham, I have never read a Stephen King book again. Graham wipes the floor with Stephen. One of the things I love about Graham is, you only have a few pages left and the main character is in such a jam, you can't think of any way out for them, but then Graham gives you a fantastic ending, that will suprise and please you. I cannot praise Graham's work enough, he is ineffable.
