Millennia after Paul Muad'Dib transformed Arrakis into a verdant world, his son Leto Atreides rules as an immortal God Emperor—a human merged with sandworm flesh and consciousness. After thirty-five centuries of absolute reign, Leto's governance is neither kind nor conventional, maintained through sacrifice and an inhuman existence. The fourth volume of Frank Herbert's epic Dune Chronicles explores the philosophical and biological limits of power, as one man's choice to transcend humanity shapes the destiny of all humankind.
