The Observers »

In Jurassic time, when dinosaurs reigned supreme, an alien civilization of microrobotic natural historians arrived on earth. Unnoticed, they have recorded the earth's history in magnificent detail. They have observed without interfering.
But government engineers in Arizona have invented something new and dangerous. The alien observers must finally introduce themselves to the human race.
Matthew Crigler, a young geophysicist, is the first person to meet the observers. He becomes a reluctant advisor to the aliens and their plans for a gentle introduction. No amount of advice can save the human race from the chaos that ensues.
