Throughout the Dune novels, Frank Herbert frequently referred to the long-ago war in which humans wrested their freedom from “thinking machines.” Now, in Dune: Butlerian Jihad, Brian Herbert and Kevin J. Anderson bring to life the story of that war, a tale previously seen only in tantalizing hints and clues. Finally, we see how Serena Butler’s passionate grief ignites the war that will liberate humans from their machine masters. We learn the circumstances of the betrayal that made mortal enemies of House Atreides and House Harkonnen; and we experience the Battle of Corrin that created a galactic empire that lasted until the reign of Emperor Shaddam IV.
