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.
Into this unstable landscape come two new factors.
From the depths of space and time, a free Titan - the near-legendary Hecate - joins forces with humanity. And in a humble laboratory on the planet Poritrin, the mathematical genius Norma Cenva is perfecting a theory that will utterly transform the rules of space travel.
