Presa (Prey)

In the Nevada desert, an experiment has gone horribly wrong. A cloud of nanoparticles — micro-robots
— has escaped from the laboratory. This cloud is self-sustaining and self-reproducing. It is intelligent and learns from experience. For all practical purposes, it is alive. Every attempt to destroy it has failed, and we
are the prey. Michael Crichton's most compelling novel yet tells the story of a mechanical plague and the desperate efforts of a handful of scientists to stop it.
Drawing on up-to-the-minute scientific fact, Prey takes us into the emerging realms of nanotechnology and
artificial distributed intelligence — in a story of breathtaking suspense. Prey is a novel you can't put down.
