Prey, Michael Crichton
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.
It has been programmed as a predator. It is evolving swiftly, becoming more deadly with each passing hour.
Condition: Good. A book that has been read but is in good condition. The book cover has no visible wear. No highlighting of text, no writing in the margins, and no missing pages.Author: Michael Crichton
