In the far future, humans and aliens have joined together in a galaxy-wide federation of intelligent species: The Consentiency, but its existence is now threatened by the discovery of a secret, illegal and deadly experiment on the planet Dosadi. There the froglike Gowachin have created a brutal society: 850 million beings, human and Gowachin, are confined in an area of 40 square kilometres.
But the experiment in overcrowding is getting out of control: the beings that have bred on Dosadi are so tough and resourceful that they are capable of breaking out of their monstrous prison and overrunning the galaxy.
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.
