"The Brotherhood of Dune," the sixth book of Frank Herbert's epic saga, concludes with a ship full of refugees venturing into the uncharted galaxy to escape annihilation. But who is the terrifying, mysterious Enemy that pursues them? Where does Leto II's Golden Path lead? What will be the fate of humanity?

Brian Herbert and Kevin J. Anderson answered some of these questions in "Hunters of Dune." However, the main question remains: Who is the ultimate Kwisatz Haderach, and how will he affect the universe?

"The Rebirth of Shai-Hulud" completes the epic of Frank Herbert's classic "Dune" universe, which began during the time of the Butlerian Jihad and extended through the original Dune series and beyond. Based on Frank Herbert's final outline, which remained hidden in a vault for a decade, they reveal the future of the beleaguered planet Arrakis, the identity of the ultimate Kwisatz Haderach, and the outcome of the war between humans and machines, answering questions that have intrigued fans of the series for over two decades.
