Query: Not His Best, But Definitely Worth the Money

This was the first time I was introduced to Dean R. Koontz. Although it is not the book that hooked me (see Watchers) it is a wonderful suspense novel. This has what has always intrigued me about his work, a mystery so complex that you will not get it until the end, no matter how hard you try. The characters are very interesting, although not as developed as his later characters are. The story line is extremely well thought out and the psychological aspect of the thriller is very interesting. Definitely a great page turner and you will love every minute of your time with this book.
