    Anderson. Working from Frank Herbert's own notes, the acclaimed authors reveal the chapter of the Dune saga most eagerly anticipated by readers: the Butlerian Jihad.Throughout the Dune novels, Frank Herbert frequently referred to the war in which humans wrested their freedom from "thinking machines." In Dune: The 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 struggle that will liberate humans from their machine masters; here is the amazing tale of the Zensunni Wanderers, who escape bondage to flee to the desert world where they will declare themselves the Free Men of Dune. And here is the backward, nearly forgotten planet of Arrakis, where traders have discovered the remarkable properties of the spice melange....

    They must act as soldier/protectors of the far more civilized races who have long since turned away from war... — Staff Sergeant Torin Kerr was a battle-hardened professional. So when she and those in her platoon who'd survived the last deadly encounter with the Others were yanked from a well-deserved leave for what was supposed to be "easy" duty as the honor guard for a diplomatic mission to the non-Confederation world of the Silsviss, she was ready for anything.At first it seemed that all she'd have to contend with was bored troops getting into mischief, and breaking in the new Second Lieutenant who had been given command of her men.Sure, there'd been rumors of the Others - the sworn enemies of the Confederation - being spotted in this sector of space. But there were always rumors. The key thing was to recruit the Silsviss into the Confederation before the Others either attacked or claimed this lizardlike race of warriors for their own side. And everything seemed to be going perfectly. Maybe too perfectly...

But her landing, with a small group of scientists and Marines, has not gone unnoticed by Aras, the planet's designated guardian.

    G. Wells, along with Jules Verne, is credited with inventing science fiction. This new volume collects Wells' best-loved and most critically acclaimed works. In each, the author grounds his fantastical imagination in scientific fact and conjecture while lacing his narrative with vibrant action, not merely to tell a “ripping yarn,” but to offer a biting critique on the world around him. “The strength of Mr. Wells,” wrote Arnold Bennett, “lies in the fact that he is not only a scientist, but a most talented student of character, especially quaint character. He will not only ingeniously describe for you a scientific miracle, but he will set down that miracle in the midst of a country village, sketching with excellent humor the inn-landlady, the blacksmith, the chemist’s apprentice, the doctor, and all the other persons whom the miracle affects.”
