Paul of Dune by Brian Herbert
Here at last is the missing history of Dune, its empire and its ruling family during those twelve action-packed years. It is a story of love and idealism; of ambition and intrigue; of war and reconciliation. Above all, it is the story of how Paul Atreides - a young man who achieved absolute power over a thousand planets when scarcely more than a boy - comes to renounce that empire and seek a new way forward for the people he rules.
