One of the earlier works of Koontz, written under a pen name, I still found it to be nearly everything a Koontz book usually is. I was a bit disappointed with the ending, simply because it seemed rather abrupt and didn't wrap things up nicely like he tends to do. Also, I'm starting to suspect that Koontz does not like cats. =) I know he's a dog lover, but I'm guessing he's suspicious of cats since this makes several books that cats have been portrayed less than positive. I suppose we all have our flaws, and that seems to be the only thing I can find resembling a flaw in Koontz. Definitely an interesting story with a fascinating concept, as always.
