Book III of Prelude To Dune. From the royal planet Kaitain, the Padishad Emperor Shaddam IV strikes at planets which defy his merciless edicts. Soon he will grasp absolute power with a new, artificial spice substitute that he alone will control. On Dune, Liet Kynes leads the Fremen as they strike crippling blows against the planet’s Harkonnen overlords. Prince Rhombur Vernius, exiled on Caladan, is ready to free his unhappy planet from the tyranny of the Tleilaxu Masters. But the final war – the one which will change the future of worlds – will be between two men: Leto Atriedes of Caladan and Vladimir Harkonnen of Geidi Prime. Cover art by Gerry Grace.
