The Caves of Steel

"With his fertile imagination, his wit, and his prolific output, Isaac Asimov truly laid the foundation for all future generations of science fiction writers."--Kevin J. Anderson, New York Times bestselling co-author of the Dune prequel series

Like most people left behind on an over-populated Earth, New York City police detective Elijah Baley had little love for either the arrogant Spacers or their robotic companions. But when a prominent Spacer is murdered under mysterious circumstances, Baley is ordered to the Outer Worlds to help track down the killer.

The relationship between Life Lige and his Spacer superiors, who distrusted all Earthmen, was strained from the start. Then he learned that they had assigned him a partner: R. Daneel Olivaw.
