It remains a foundational space opera known for its worldbuilding and long-running influence on the science fiction genre.
Foundation
Isaac Asimov’s Foundation centers on mathematician Hari Seldon, who uses psychohistory to forecast the collapse of a galactic empire and designs a plan to shorten the coming dark age.

The protagonist, Winston Smith, works within the machinery of propaganda while privately resisting its grip, which draws him into escalating danger. Frequently categorized as dystopian fiction with strong science fiction elements, the novel remains a reference point for discussions of authoritarianism, mass monitoring, and engineered reality.
Brave New World
Aldous Huxley’s Brave New World presents a society stabilized through engineered reproduction, social conditioning, and pleasure-based control rather than overt terror.

H. G. Wells’s The War of the Worlds follows a narrator witnessing an alien invasion of England, as Martian technology overwhelms existing military and social structures. The story emphasizes panic, displacement, and the collapse of assumptions about human dominance, offering an early and influential depiction of extraterrestrial contact as catastrophe. It remains a cornerstone of invasion science fiction and helped set patterns still used in modern alien invasion stories.
Neuromancer
William Gibson’s Neuromancer follows Case, a washed-up hacker hired for a high-risk job that pulls him into corporate intrigue, artificial intelligence, and a sprawling digital underworld.

Its language and concepts influenced later depictions of cyberspace, hacking culture, and the social impact of advanced computing.
The Martian
Andy Weir’s The Martian focuses on astronaut Mark Watney after a mission accident leaves him stranded on Mars with limited supplies and no immediate rescue plan.
