Read Sandworms of Dune

Thirty-five years before Dune: Leto is sent to Ix as a boy, Pardot Kynes reaches Arrakis, and Shaddam plots his own father's death.

Gurney Halleck in the Harkonnen slave pits, Duncan Idaho training on Ginaz, and Jessica sent from the Sisterhood to Caladan.

The Emperor's synthetic-spice project on Ix collapses while Leto goes to war over it; the trilogy ends with the birth of Paul.

Ten thousand years earlier: humanity revolts against the thinking machines, and Serena Butler gives the war its name.

Twenty-four years into the jihad: Vorian Atreides against the Titan Agamemnon, and Norma Cenva working out how to fold space.

The jihad ends with atomics over Corrin, and the Corrino empire, the Spacing Guild and the Great Convention come out of the wreckage.

Picks up the cliffhanger Frank Herbert left in 1985: the no-ship runs from an enemy the Bene Gesserit cannot name, with a hold full of gholas.

Alternates between Paul's twelve-year jihad after Dune, fought across the galaxy in his name, and his boyhood on Caladan.
