Dune Messiah &, Children of Dune

Children of Dune: "When Paul Atreides mysteriously vanished, he left only his two young children as heirs to the coveted throne. Fortunately they had been endowed with superior intelligence and the memories of their ancestors, for each day brought them new dangers. When one was abducted, the other was forced to seek sanctuary in the scorching flatlands. There his mind began to swirl with thought-patterns from strange times and places, warning him of the terrifying perils awaiting Dune ... giving him an improbable plan to save it ... and predicting his destiny as ruler of the world. But were these messages real– or the delusions of a mind deranged by heat, exhaustion and the addictive spice, Melange?"–Jacket.
