Review From User :

I loved this book. It was very creative and imaginative and very strange in a "good way". I think Michael Crichton is one of the best if not the best Science Fiction writers!
I highly recommend this book and give it 5 shining stars

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.

Every attempt to destroy it has failed.

And we are the prey.
