Query: Don't miss this one

I strongly recommend that you don't let this one get away. The Truth Machine is in a league of it's own - much better than The Immortal. I can't remember ever having been this moved by a book or a movie for that matter. Halperin describes a truly fascinating and believable scenario: What does it take to build a Truth Machine and what effect could it have on our way of living! I'm not usually a big fan of prophecies and predictions about the future but this book really has some unique observations about the possible consequences of the introduction of a truth machine to the world. You will be surprised at the end (I know I was).
