Dune. The Butlerian jihad
(Book)

"A Tom Doherty Associates book."

"Ten thousand years before the events of Dune, humans have managed to battle the remorseless Machines to a standstill . . . but victory may be short-lived. Yet amid shortsighted squabbling between nobles, new leaders have begun to emerge. Among them are Xavier Harkonnen, military leader of the Planet of Salusa Secundus; Xavier's fiancée, Serena Butler, an activist who will become the unwilling leader of millions; and Tio Holtzman, the scientist struggling to devise a weapon that will help the human cause. Against the brute efficiency of their adversaries, these leaders and the human race have only imagination, compassion, and the capacity for love. It will have to be enough." --publisher's website
