Dune Messiah continues the story of Paul Atreides, better known--and feared--as the man christened Muad'Dib.

Worshipped as a religious icon by the fanatical Fremen, Paul faces the enmity of the political houses he displaced when he assumed the throne--and a conspiracy conducted within his own sphere of influence.

And even as House Atreides begins to crumble around him from the machinations of his enemies, the true threat to Paul comes to his lover, Chani, and the unborn heir to his family's dynasty...
