On the distant planet Dreenor lives the most powerful species in the Galaxy. All of the Universe is the creation of the Dreens, who possess the power of "idmaging", turning their throughts into reality. They can create whole worlds, of which the wild, ungovernable planet Earth is one. But suddenly Earth is a threat, its people on the verge of discovering interstellar travel, and with it, of gaining access to Dreenor itself – a paradox within a paradox, not to be permitted.
While the elder Dreens plan Earth's destruction, a youngster, Ryll, embarks on an unauthorised jaunt across space. Forced for survival to merge bodies with an Earther whose mind is as strong as his own, he has to battle for control. And the future of all earthly life lies in the hand of a composite being, half wily, aggressive human, half naive adolescent alien, confused and far from home.
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.
