Children of Dune follows the young twins of Paul Atreides, Leto and Ghanima, who grow up on Arrakis under the watch of their scheming relatives. The planet is slowly changing as its desert is made greener, and some of the Fremen fear that their old ways and strength are being lost.
The children possess unusual inherited memories and awareness, and enemies at court and beyond want to use or destroy them. The book explores ecological change, religious power and the heavy burden of guiding humanity's future.
