Despite malevolent lifeforms and the implacable hostility of Ship, the self-styled God demanding human WorShip, Mankind's struggle to colonise the bleak ocean planet Pandora has been at least partially successful.
But at what cost! Genetic mutation has evolved two seperate societies, human subspecies: the technologically advanced Mermen, who live in sophisticated undersea habitats and dream of plundering Ship itself;and the Islanders, who inhabit huge organic raft cities, and whose way of life depends on biological engineering. Their uneasy coexistence is always imperilled, but the results of one Merman project threatens to precipitate open conflict, and human extinction.
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.
