Mentats of Dune

Mentats of Dune is a 2014 science fiction novel by Brian Herbert and Kevin J. Anderson, set in the Dune universe created by Frank Herbert. It is the second book in their Great Schools of Dune prequel trilogy, which itself is a sequel to their Legends of Dune trilogy. Set nearly a century after the events of 2004's Dune: The Battle of Corrin, the novel continues to chronicle the beginnings of the Bene Gesserit, Mentat and Suk Schools, as well as the Spacing Guild, all of whom are threatened by the independent anti-technology forces gaining power in the aftermath of the Butlerian Jihad. The Great Schools of Dune trilogy, first mentioned by Anderson in a 2010 blog post, chronicles the early years of these organizations, which figure prominently in the original Dune novels.
