I don't think this is one of Koontz's best; it is probably an early book. Still, it does have some very surprising characters! The good "guy" is actually a dog; the "bad" guy is a malevolent creature. As is usual with Koontz, there is the mixing up of DNA to get these results. Add to that a nice mix of human characters that interact with the "man-made" creatures. The most interesting is what that dog can do! The least interesting is Koontz's preaching...but there isn't enough of it to not read the book. I mean, everyone should read about a dog that thinks like a human. Besides, I really think I would be able to beat him at Scrabble!
