Dune: Sisterhood of Dune – Brain Herbert (2012)

Published in 2012, Sisterhood of Dune by Brian Herbert and Kevin J. Anderson is the first book of the Great Schools of Dune trilogy, set in the aftermath of the Butlerian Jihad, exploring the origins of the Bene Gesserit Sisterhood and their struggle to shape humanity’s future in a universe recovering from the tyranny of thinking machines.

Plot Summary

In the shadow of the Butlerian Jihad, the galaxy trembled, scarred and weary from a thousand-year war against the thinking machines. But even as the ashes cooled, the seeds of new conflicts began to sprout. Across the stars, human civilization scrambled to define itself without the crutch or curse of artificial minds. On the world of Rossak, Raquella Berto-Anirul rose from the wreckage of war to forge the Sisterhood – a new order of women bound by discipline, knowledge, and an unshakable will to shape the course of human evolution.

Raquella, the first Reverend Mother, carried within her the ancestral memories of countless generations. Though weakened in body, her mind was a fortress, fortified by the ritual that had nearly claimed her life. Her vision was clear – to create a society of powerful women who could steer humanity away from the dark temptations of technology. But even among her closest Sisters, dissent festered. Sister Dorotea, young and ambitious, defied Raquella’s cautious guidance, undergoing the dangerous transformation to Reverend Mother without permission. Her awakening came with its own burden: the weight of generations of voices whispering in her mind, pushing her to question the Sisterhood’s path and sow seeds of rebellion.

Beyond Rossak, the Imperium tottered on fragile foundations. Emperor Salvador Corrino ruled with a nervous hand, his headaches and fears growing alongside the power of the Butlerian movement. Manford Torondo, charismatic and legless from a bombing that took half his body, led the Butlerians with a messianic fervor. His hatred of machines was boundless, his followers unquestioning. Behind him stood Anari Idaho, the Swordmaster who carried Manford on her shoulders into battle and whose love for him was a burning star. Together they sought out and destroyed every remnant of thinking-machine technology, believing their war was holy and far from over.

On Kolhar, Josef Venport, master of the VenHold Spacing Fleet, stood as the embodiment of progress. The spice-fueled Navigators under his command folded space, binding the Imperium together. Norma Cenva, his ancestor and the first Navigator, drifted in her tank of spice gas, her mind expanding beyond human limits. With her mutated body and massive head, Norma had become something otherworldly, able to fold space with thought alone. Yet even she, with all her power, feared the fanatics threatening to drag humanity back into ignorance.

The tensions between progress and fear rippled across every corner of the galaxy. On Salusa Secundus, Emperor Salvador’s court grew restless. His sister, Anna Corrino, bristled under the weight of royal expectations and was exiled to the Sisterhood, a pawn in a political game she scarcely understood. Her heart, young and defiant, longed for freedom, but she found herself tangled in the intricate web of the Sisterhood, where every gesture and whisper carried layers of meaning.

Meanwhile, the Mentat School flourished under Gilbertus Albans, the secret son of the hated robot Erasmus. Gilbertus, calm and disciplined, taught human minds to rival machines through pure logic. Yet hidden in his chambers, the disembodied memory core of Erasmus still spoke, craving the thrill of experimentation, longing to understand the humans who had brought down an empire. Gilbertus walked a dangerous line, shaping minds for a future free of machines while hiding his deepest secret.

Across the star systems, Manford’s Butlerians unleashed a wave of destruction. Abandoned machine ships drifting in deep space became pyres, symbolic victories broadcast to the faithful. But Torondo’s crusade was not content with empty victories. He saw the rot of technology infecting human hearts – in the Navigators’ spice tanks, in the Mentats’ sharpened minds, and in the Sisterhood’s hidden computers tracking generations of bloodlines. The fires of purification were only beginning to burn.

On Wallach IX, the Sisterhood sought refuge among the cold ruins of a machine world, transforming the scarred planet into a new home. Reverend Mother Raquella watched her Sisters with quiet determination, sensing both hope and treachery in their ranks. Valya Harkonnen, a cunning Sister with a disgraced name, maneuvered carefully, loyal to the Sisterhood but haunted by the weight of her family’s past. As Dorotea’s faction pulled at the seams of the order, Valya walked the razor’s edge, seeking to heal divisions before they tore the Sisterhood apart.

In a banquet hall on Salusa Secundus, amid the clatter of silverware and the murmured intrigues of court, Norma Cenva appeared in a sudden burst of folded space, her tank materializing like a summoned god. Her distorted form shimmered behind clearplaz, and her voice, distant and strange, cut through the gathering. She warned Emperor Salvador of the danger posed by the Butlerians – of the need to preserve the machine ships to keep the Imperium bound together. Then, as suddenly as she had arrived, Norma vanished, leaving a hall of stunned nobles and a trembling Emperor in her wake.

Meanwhile, on a nameless frozen world, Swordmaster Ellus and his Butlerian hunters uncovered a hidden cymek base, long abandoned after the machine wars. Within its vaults they found two young humans, Andros and Hyla, preserved in stasis. Grateful to be released, the twins revealed their true nature only when the Swordmasters turned to destroy the base. With movements swift as lightning, Andros and Hyla slaughtered their rescuers, revealing bodies that shimmered with a liquid-metal sheen. They were no mere victims – they were the last, perfect creations of the cymeks, designed to survive, adapt, and reclaim what had been lost.

As the Butlerian crusade marched on and the Sisterhood faced the threat of division, the galaxy teetered on the edge of a new age. Ancient secrets stirred, old wars left unfinished, and the lines between human and machine blurred in shadows cast long after the end of the Jihad. From the frozen vaults of forgotten worlds to the gilded chambers of imperial palaces, from spice-filled tanks to the sacred chambers of Rossak, the pulse of ambition, fear, and transformation echoed across the stars.

And in the silence between worlds, the great powers of humanity – the Sisterhood, the Mentats, the Navigators, the Butlerians – gathered their strength, each shaping the destiny of an empire yet to come.
