Query: Good stuff

For years, I have considered reading Koontz novels a guilty pleasure, but this one was amazing. It was richer than his previous works and was filled with more hope. In a lot of ways, it reminded me of "Twilight Eyes", which was also about redemption and a kind of end to the world. The spiritual turn to the book really rang true to my own beliefs. The mainstays of kootzian fiction were present; writers, dogs, California, but it was more substantial and earnest. Very good read!
