A terrifying page-turner in classic Crichton tradition, masterfully combining the elements of a heart-pounding thriller with cutting-edge technology. The result is a tale so realistic, so scary, readers won&8217;t be able to put it down. Deep in the middle of the Nevada desert, the Xymos Corporation has built a state-of-the-art fabrication plant, surrounded by miles and miles of nothing but cactus and coyote. Eight people are trapped inside - because outside, waiting for them, looking for them, is a self-replicating, fast-evolving swarm made up of predatory molecules that they themselves created. On a singular level, the molecules are seemingly harmless, but massed together, they form an intelligent organism that is anything but benign. It&8217;s getting bigger and more powerful by the hour, and it has targeted the eight humans as prey. They must find a way to stop this creature before it gets inside-unless it&8217;s already too late... Once again, Michael Crichton combines scientific brilliance with relentless pacing to create an electrifyingly chilling techno-thriller.
