Science Fiction Adventure of All Time Dune Messiah continues the story of Paul Atreides, better known—and feared—as the man christened Muad’Dib. As Emperor of the known universe, he possesses more power than a single man was ever meant to wield. 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...
The ban on thinking machines seems like something that's particularly relevant in the age of AI. Will we reach that stage as well (post WW3, perhaps?) or will AI be benevolent and benefit society?
You should probably read Children of Dune to round off the trilogy, just to learn the fate of Paul Atreides, although he is not the primary character in that book.
The second trilogy is distinct but the stories are told told in the same setting; enjoyable but not essential.
The problem is that just like the other characters the in novel, Paul's family, adherents and friends, a lot of readers just want an uncomplicated hero story for him.
Highly recommended.
I would also recommend Dune, but unlike some of the other commenters, I would recommend the entire series. At the very least, read Dune and Dune Messiah together. (I found the first 100 pages or so of Dune a bit tough going, but once you get into it, it's fantastic.)
