Query: You won't be able to put it down--GUARANTEED!

This is not great literature like "The Scarlet Letter" or "Brother's Karamazov" but it is the best at what it attempts to be--possibly the most suspenseful, can't-put-it-down thriller ever written. The tension is wound so tight that I actually HAD to put it down to collect myself and catch my breath. The guy who gave it one star is seriously delusional and bitter.
