Three men are found dead in the locked second floor office of a Honolulu building, with no sign of struggle except ultra-fine, razor-sharp cuts covering their bodies. The only clue left behind is a tiny bladed robot, nearly unrecognizable to the human eye. In the lush forests of Oahu, an advance in micro-robotics has put unheard-of resources at the fingertips of science; trillions of previously unknown micro-organisms, tens of thousands of species of bacteria, are being discovered, feeding a search for new life-saving drugs and profitable applications on a scale beyond anything previously imagined. In Cambridge, Massachusetts, a group of graduate students at the forefront of their fields are recruited to work at a cutting-edge microbiology start-up. Nanigen MicroTechnologies' exploratory work is conducted under a veil of secrecy and promises the young researchers the chance to wield unprecedented new tools at the limits of scientific discovery. To participate they must commit now and come to Hawaii--or be left behind and watch their peers reap the rewards. But when the true costs of Nanigen's innovations are revealed in Oahu, the graduate students find themselves cast out of the stable certainties of the lab, thrust into a hostile wilderness, prey to a technology of radical and unbridled power. An instant classic, Michael Crichton's boundary-pushing and up-to-the-minute final thriller has all the hallmarks of his greatest adventures. And no one is better suited to complete this novel than visionary science writer Richard Preston: pitting nature against technology in vintage Crichton fashion, Micro melds scientific fact with pulse-pounding fiction to create yet another masterpiece of sophisticated, cutting-edge entertainment.
