These immortals, the Optimen, rule mankind, and from their Central Headquarters monitor every subversive action against them, destroying it immediately. For, despite their optimum bodies, these "humans" do have enemies – it could be the Cyborgs, long considered destroyed, it could be the Parents Underground, striking back for family and natural birth, or it could be – death itself.
Franklin Patrick Herbert, Jr. (1920–1986) was a critically acclaimed and commercially successful American science fiction author. Though also a short story author, he is best known for his novels, most notably Dune and its five sequels. The Dune saga, set in the distant future and taking place over millennia, deals with themes such as human survival and evolution, ecology, and the intersection of religion, politics and power. Dune itself is the "best-selling science fiction novel of all time," and the series is widely considered to be among the classics in the genre.
