Dune was a great read the first time I read the book and is still a great read. It’s the first environmentally conscious sci-fi story I can remember reading. There are a lot of made up words in the story. Wikipedia repeatedly referenced Frank Herbert when I looked up words. The Terminology of the Imperium at the back of the book has about 300 made up names and words in it. For readers who want more Frank Herbert’s son and Kevin J. Anderson are still writing Dune books.
