Dune is a science fiction novel written by Frank Herbert, published in 1965. It won the Hugo Award in 1966, and also the inaugural Nebula Award for Best Novel. Dune was also the first bestselling hardcover science fiction novel, and it is frequently cited as the world's best-selling science fiction novel. Set in the far future amidst a sprawling feudal interstellar empire where planetary fiefdoms are controlled by noble houses that owe an allegiance to the Imperial House Corrino, Dune tells the story of young Paul Atreides (the heir apparent to Duke Leto Atreides and the scion of House Atreides) as he and his family accept control of the desert planet Arrakis, the only source of the "spice" melange, the most important and valuable substance in the universe. The story explores the complex and multi-layered interactions of politics, religion, ecology, technology, and human emotion, as the forces of the Empire confront each other for control of Arrakis and its "spice".
