Well its a series by Frank Herbert, I know that his son is continuing with the series by doing a few books about its history and other stuff (kinda like JRR Tolkiens son). I think his sons name is Brian Herbert.
I'd reccomend starting with the first book, Dune.
Here's the official website listing:
http://www.dunenovels.com/classic.htmlThere are 6 books of Dune by Frank Herbert. After that you might consider reading some of the others by his son (also on the site somewhere)
I've only just finished the third one, Children of Dune, and I can't seem to find a copy of the fourth.
They are all brilliant but I would advise starting from the begining (Dune by Frank H), otherwise you could lose track pretty easily. Afterall, the series spans over a few generations, each book kinda covering one generation.
Have you played the games at all?
Have you ever heard of the Fremen or the Atredies?
