5 A masterclass in thriller writingrobspi | 14/12/2009 | See all robspi's reviews (13)Top 100 Books Reviewer From the very first page you will be hooked. What would have been a very ordinary plot in most author's hands is utterly gripping, full of twists and leads to a satisfactory conclusion in the hands of the master Koontz. I was never a massive Koontz fan before i read this, but it is a seemingly simple yet expertly told thriller that leaves you turning page after page in your quest to find out what really is going on. 464 Pages flies by in no time. I have since discovered many other Koontz books have similar appeal, such as Velocity, Life Expectancy to name but two. I now read a Koontz every 2 or 3 books (I never read 2 books by the same author back to back), and always smile when it is one of his books next on the list!
