Beware the man who rides the shoulders of heroes with a closed mind. Beware the Bene Gesserit who's mind is so open she doesn't see the trouble closest to her. And beware the Sister who's mind is open only to revenge. The war against the machines has been over for eight decades and mankind seems to be forgetting the terror of being ruled by these horrors. Even the Bene Gesserits use computers in secret. But the Butlerian movement will not let anyone forget and has set out to destroy all who prefer using machines. Vorian Atreides has turned his back on politics in hope for peace. But there are still those who would find him either to eliminate or try to get him to join in ruling as the machines intended. Naturally the Butlerians would have him dead. This is a brilliant novel of horrible extremes fighting each other with most of humanity in the center of the storm. Manford and his Butlerian followers could throw the entire human race into total chaos and a new dark ages. Herbert and Anderson have done a magnificent job of keeping the tradition of great sci fi in the continuing saga of Dune.
