The book Dune by Frank Herbert

Melange, or spice, is the most valuable and rarest substance in the universe, capable of everything from extending life to facilitating interstellar travel. And it can only be found on one planet—the inhospitable desert planet of Arrakis. Whoever rules Arrakis controls the spice. And whoever controls the spice rules the universe. When the Emperor strips the Harkonnen clan of their rulership and gives it to the Atreides, the Harkonnens kill Duke Leto Atreides. His son Paul and his concubine Jessica flee into the desert. To avenge his father and reclaim the planet from the Harkonnens, Paul must gain the trust of the Fremen—the indigenous inhabitants of Arrakis—and lead a tiny army against the overwhelming forces of the enemy.
