What is the author's style in God Emperor of Dune by Frank Herbert?

God Emperor of Dune expands upon Frank Herbert's best selling planned trilogy (Dune, Dune Messiah, and Children of Dune), looking 3,000 years into the future. Like the earlier works, it is narrated in straightforward Standard American English, using contractions, but avoiding the tendency of many science fiction writers to incorporate contemporary idioms that quickly date their works. Dialog is far more important than in the earlier volumes, driving the story and building up the characters.
