This is not the edge-of-the-seat thriller that some of his books are. As always there is some very disturbing evil all at the hands of human. This time the supernatural forces are on the side of the good, and in the form of the dog.
I was a bit confused about the character Theresa, a young autistic girl. Koontz seemed to be building her up for a larger part in the story, but rather, the last we hear of her is a maybe or maybe not sighting through a window.
An entertaining book, although a tad sugary— but then Golden Retrievers are very sweet, so what did I expect?
