The Great Dune Trilogy

Herbert's evocative, epic tales are set on the desert planet Arrakis, the focus for a complex political and military struggle with galaxy- wide repercussions. Arrakis is the source of spice, a mind enhancing drug which makes interstellar travel possible; it is the most valuable substance in the galaxy. When Duke Atreides and his family take up court there, they fall into a trap set by the Duke's bitter rival, Baron Harkonnen. The Duke is poisoned, but his wife and her son Paul escape to the vast and arid deserts of Arrakis, which have given the planet its nickname of Dune.

Paul and his mother join the Fremen, the Arrakis natives, who have learnt to live in this harsh and complex ecosystem. But learning to survive is not enough - Paul's destiny was mapped out long ago and his mother is committed to seeing it fulfilled.
