Query: One of my favorite Koontz Books

This is one of my favorite Dean Koontz books! I own it i hardcover, and read it at least once a year. Sometimes I find that when life isn't going as well as I'd like, I can read this book and it perks me right up. The undercurrent of hope and happiness in this story really lift my spirits. Yes, there are the usual Koontz twists, and an evil villian that is likable and pitiable, but still a villian. But under it all, Koontz brings you through this story and leaves you feeling better.
