Query: a different Koontz book

I have read many, many of Dean Koontz's books and I will say that 99% of the time I have enjoyed them immensely. This book, I think, was written a while ago but as always it's a page turner! Can't put it down, just like all his books!I also did like that the main characters were young adults. That is one of the aspects about his writing that drew me in many years ago, that his hero's & heroines can be woman, children even animals instead of always men! Not that I mind when his protagonists are adult men, but it's nice to have the variety!It's an interesting story and I recommend it to any Dean Koontz fan, but maybe for a new reader start with "Watchers"
