This has been lurking on my shelves for a number of years, and finally got around to picking it up and reading it.
The Atredies family has been sent to the planet Arrakis, source of spice. They are betrayed by the previous family Harkonnens, the Duke is murdered and Paul, and his mother are thought to be killed by a storm. Paul and his mother survive, and using his Bene Gesserit skills he becomes a leader and a focus for the Fremen, the people of the desert. All through the book it is thought that he is the Kwisatz Haderach, a person of unique power and insight.
I really enjoyed this, the plot and sub plots were excellent, the way that he manages to deal with the large scale family intrigue and political manoeuvring, as well as the detail on this planet that he has created. Great book, wish that I had read it earlier now!
