Chapterhouse: Dune

Plot

The Honored Matres have nearly finished conquering the Old Empire, and they are now hunting the Bene Gesserit. Their goal is to absorb the Sisterhood’s advanced technology and superhuman abilities, then wipe them out entirely. Darwi Odrade, the current Mother Superior of the Bene Gesserit, is pushing forward a risky and secret strategy to counter this threat. Meanwhile, the Sisterhood is reshaping the planet Chapterhouse through terraforming, trying to make it suitable for sandworms after the Honored Matres destroyed Dune.

Sheeana oversees this project and believes sandworms will emerge soon. The Honored Matres have also annihilated the entire Bene Tleilax civilization, leaving only one Tleilaxu Master alive: Scytale. He is now a prisoner of the Bene Gesserit, and he possesses the secret to creating gholas. In exchange for protection, he has reluctantly shared this knowledge.

The first ghola produced is Miles Teg, the Sisterhood’s recently deceased military strategist. Two other prisoners are held on Chapterhouse: the latest ghola of Duncan Idaho and his lover, Murbella, a former Honored Matre. The Bene Gesserit have accepted Murbella as a novice, though they suspect she plans to escape back to her own people. The Honored Matres also destroyed Lampadas, a key Bene Gesserit educational center.

Its Chancellor, Reverend Mother Lucilla, escaped carrying the collective memories of millions of Reverend Mothers. Forced to land on Gammu, she sought refuge with a hidden Jewish community called Secret Israel. The Rabbi who leads them granted her sanctuary, but to protect his people from the Honored Matres, he eventually had to hand her over. Before doing so, he revealed Rebecca, a wild Reverend Mother who had gained Other Memory without formal Bene Gesserit training.

Lucilla shared minds with Rebecca, who agreed to carry the Lampadas memories safely back to the Sisterhood. Lucilla was then betrayed and brought before the Great Honored Matre Dama. Dama tried to convince Lucilla to join the Honored Matres, offering to spare her life in return for Bene Gesserit secrets. The Honored Matres were especially eager to learn how to voluntarily alter their own body chemistry—a skill that had faded among the Bene Gesserit who left during the Scattering and later became the Honored Matres.

Reception

Chapterhouse: Dune reached number two on the New York Times bestseller list after entering at number five. In a review, Gerald Jonas observed that the Dune universe, against expectations, continues to grow more textured and morally complex. Dave Langford, writing in White Dwarf #65, praised its sharp characters and thoughtful, humane conclusion, noting that after giving up on the series following Children, this novel and Heretics partly restored his faith.
