Fifteen hundred years after the death of the God Emperor, the scattered peoples of the galaxy are returning. The Scattering - Leto II's final gift to humanity - sent millions fleeing beyond the reach of prescience, and now their descendants are coming home, bringing new technologies, new religions, and new dangers. On Rakis, the planet once called Dune, a young girl named Sheeana can control the reborn sandworms. The Bene Gesserit want her. The Tleilaxu want her. And from the Scattering, a terrifying new enemy is approaching - one the old powers of the galaxy may not survive.
