Mentats of Dune is the second book in the Schools of Dune Trilogy by Brian Herbert and Kevin J. Anderson. The galaxy continues to be ravaged by the Butlerians. Manford Torondo's ego is matched only by Josef Venport who opposes the cultist with a vengeance. Due to Dorotea's Butlerian loyalties the Sisterhood is now fractured with Mother Superior Raquella trying to figure out a way to repair the damage. Valya Harkonnen could be the next Mother Superior though her goals aren't fully with the Sisterhood. Gilbertus Albans, Headmaster of the Mentat school, has done his best to appease Manford but finds that alliance quickly falling apart. Now the question is will Gilbertus continue to appease Manford or take a stand for humanity?
