Hunters of Dune

Picking up directly from Chapterhouse: Dune, Hunters of Dune begins the resolution Frank Herbert outlined before his death. The Bene Gesserit ship Ithaca flees into the unknown, gholas of Paul, Leto II, and other key figures are grown on Chapterhouse, and the Enemy that drove humanity to scatter starts to reveal itself.

Read it after Chapterhouse: Dune; it is paired with Sandworms of Dune as a single finale.
