Chapterhouse: Dune

A stirring finish to Frank Herbert's portion of the Dune Chronicles however THIS IS NOT THE END OF THE DUNE CHRONICLES. The end of the book is a really bad cliff hanger resolved in books written by Brian Herbert and Kevin J Anderson, which to the best of my research were written from a 30 page manuscript found years after Frank Herbert died. The last two books are called "Hunters Of Dune", and "Sandworms Of Dune" again by Brian Herbert and Kevin J Anderson.
