Lord of Light (1967) is a science fantasy novel by American author Roger Zelazny. It was awarded the 1968 Hugo Award for Best Novel, and nominated for a Nebula Award in the same category. Two chapters from the novel were published as novelettes in the Magazine of Fantasy and Science Fiction – "Dawn" in April 1967, and "Death and the Executioner" in June 1967.

Zelazny noted that Lord of Light was written so that it could be taken as a science fiction or a fantasy novel. The context of the novel is modern western characters in a Hindu-Buddhist-influenced world. (from Wikipedia)
