About the book

Two centuries after Elijah Baley helped settlers from Earth reach new worlds, their expanding civilization rivals the older Spacer societies. On Solaria, the humans have disappeared, and robots attack visiting salvage crews. D.G. Baley, Elijah’s descendant, recruits Solarian-born Gladia Delmarre to investigate, accompanied by her robots Daneel Olivaw and Giskard Reventlov. A conspiracy threatens Earth, while the robots struggle to protect humanity under laws written to prevent harm to individual people.

Reader notes

Much of the science fiction unfolds through extended conversations and logical arguments, so the pace is deliberate even when the stakes are planetary. Flashbacks recall Elijah Baley, and familiarity with the earlier Robot novels helps: returning relationships and debates carry more weight than action.

Questions readers ask

Do I need to read the earlier books first?

Not really, but familiarity with the earlier Robot novels helps. This is the fifth entry in the Robots series, and returning relationships, flashbacks to Elijah Baley, and continuing debates carry more weight with that background.

Is it hard to read?

The prose is direct, but the ideas require attention. Extended conversations and logical arguments do much of the work, especially as the robots consider how to protect humanity under laws designed to prevent harm to individuals.

Is it more mystery or action?

The mystery centers on vanished humans on Solaria, robots attacking salvage crews, and a conspiracy threatening Earth. Investigation and philosophical debate carry more weight than action, with a deliberate pace even when the stakes are planetary.

What moral questions does it explore?

The central tension is between protecting individual people and protecting humanity. Daneel and Giskard struggle with laws written to prevent individual harm while expanding settler civilization rivals the older Spacer societies and a conspiracy threatens Earth.

468 pages in the Ballantine Books 1986 mass market paperback edition.

About the author

Isaac Asimov

Isaac Asimov was an American writer and biochemist whose range extended far beyond science fiction, into explanatory books on science, history, literature, and religion. His fiction uses clear, unornamented prose and often advances through dialogue, argument, and the patient testing of an idea. He could pair that surface directness with intricate construction, including linked stories and chapters arranged outside chronological order. Foundation follows an institution across successive generations, turning imperial collapse into a sequence of political and intellectual crises rather than a single hero’s campaign. In I, Robot, an interview with robot psychologist Susan Calvin binds separate cases into a larger history of human dependence on machines. Each apparent malfunction becomes a logical problem produced by the collision between fixed rules and contradictory human commands. His recurring interests lie in systems meant to govern behavior or history, and in the exceptions that expose their limits.
