Leto II has ruled for more than three thousand years by trading his humanity for the body and lifespan of a sandworm, and the fourth Dune novel is largely an argument about what that rule has bought.
Frank Herbert sets the book far beyond the close of Children of Dune, on an Arrakis transformed almost past recognition. Much of the narrative is given to the God Emperor's own reflections on breeding programmes, prescience, rebellion and the long path he believes humanity must be forced down. It is the most philosophical entry in the sequence, driven by argument and interior monologue more than by action.
A few specifics:
• Fourth novel in Herbert's original Dune sequence
• A time jump of millennia from the preceding book
• Extended meditations on power, tyranny and the survival of a species
• Orion Books edition for readers continuing the series
