The book "Lord of Light", was written by whom?

The book Lord of Light was written by Roger Zelazny. Published in 1967, it is a science-fantasy novel about colonists who use advanced technology to assume the identities and powers of gods from Hindu and Buddhist traditions.

The story takes place on another planet settled by survivors of a spacecraft expedition. Through biological engineering, mind transfer, and control over reincarnation, a ruling group maintains power over later generations. The central figure, Sam, challenges that order, creating a conflict that blends futuristic technology with religious mythology.

Lord of Light is notable for deliberately straddling science fiction and fantasy. It won the Hugo Award for Best Novel in 1968 and was also connected to an extraordinary Cold War-era episode: a proposed film adaptation inspired a cover story that helped the CIA rescue American diplomats from Iran in 1980. That episode later became part of the story behind the film Argo.
