I really liked this book. Koontz is an awesome story teller, he really knows how to paint a picture and make the most out of otherwise minor details of a story. The action was pretty constant and I was always hooked to find out what happened next, and the ending was good too!
The only issue I had was that Koontz is more poetic in his descriptions than I'm used to. After a few chapters I got used to his style though and all was good.
I think the best part (after having just read 2 Dan Brown books) is that there were no parts where I rolled my eyes and thought, "thats lame but I'll buy it for the sake of the story". This story was pretty solid all around.
