House Atreides - Brian Herbert

It is the year 10,154 of the Imperial Calendar, and for four decades the planet Arrakis - called Dune by its inhabitants - has been ruled by the Harkonnen family.
But the seeds of change have been sown. On Arrakis, an idealistic young planetologist, Pardot Kynes, goes out into the desert to learn the secrets of its giant sandworms and the priceless Spice they create.
And on another planet, Caledon, young Leto Atreides is nearly ready to become duke.
The blood feud between House Atreides and House Harkonnen is about to begin.
Drawing on notes, outlines and correspondence Frank Herbert left behind at his death, House Atreides is a breathtaking story of war, treachery, decadence and steadfastness in the face of overwhelming odds.
