Children of Dune

Reread Dune Dune Messiah and Children of Dune. Highly recommended.

Dune, Dune Messiah and Children of Dune by Frank Herbert are my favorites. the sequels God Emperor, Heretics of Dune and Chapterhouse were good as well but I like the 1st three the most. Dune was about how people shouldn't let supermen lead. it was complex. it was an ecological novel. they had quotable quotes like "thou shall not make a machine in the likeness of the human mind". people say it's the lord of the rings of science fiction. the characters are rich, the plot thick. i highly recommend Dune.
