In The Machine Crusade the story of the battle between humans and the thinking machines continues from where it began in The Butlerian Jihad.

The first battle was a victory. But the war is just beginning . . .

Earth is a radioactive ruin. But the initial campaign of the Butlerian Jihad has given new hope to mankind. Serena Butler, whose murdered child has become a symbol for oppressed humanity, inspires a war against the thinking computers led by Xavier Harkonnen and Vorian Atreides.

But four of the Titans - murderous machines with human brains and human cunning - still remain. And the universal computer mind, Omnius, still wields most of its power.
