Prometheus Award Hall of Fame finalist and one of the 100 best science fiction novels from 1949-1984 as selected by critic David Pringle.

This classic of libertarian science fiction explores how the citizens of a near-future Los Angeles wrestle with poverty, privacy, and technology when faced with a choice between corporate feudalism and government dysfunction.

In a dystopian future, where pollution, overpopulation, and violence overrun Los Angeles streets, a Utopia flourishes. Todos Santos is thousand-foot-high arcology, a self-contained single-structured city that rises above the festering skyscrapers to offer its privileged residents the perfect blend of technology and security in exchange for their oath of allegiance and vigilance.

But is this orderly city elevating humanity, or shackling it? There are those who feel the constant video surveillance oppressive, rather than inclusive, or that the city is monopolizing hard-earned resources, and taking money away from the poorer Angelinos.

Connected through neural implants to MILLIE - the AI that runs all of Todos Santos' systems - Art Bonner and Barbara Churchwood work with a team of dedicated staff to protect the city against the FROMATEs ("Friends of Man and the Earth"), who are a group of anti-technology zealots dedicated to destroying everything they have built. When three youths break into the city, to see if they can exploit its weaknesses, the repercussions of their actions threaten to bring one of humanities most ambitious projects to its knees...

Published in 1981, Oath of Fealty is one of several works by Larry Niven and Jerry Pournelle, including The Mote in God's Eye (1974) and Lucifer's Hammer (1977).
