Query: More like Night Boredom

If you plan on being bored out of your mind by a book you thought was going to be a psychological thriller, think again. I had more terror watching my cat stare at me while I tried to read than I did from any chapter in this perpetuating bore. A Koontz book that I found truly impressive was Shadowfires. I believe that is his best work thus far.
