Read Dune many years ago and saw the original film as an adaptation just as we have to see Sky's DW film's. That was the one with Sting in it. I have that and the DVDs of Dune and Children of Dune. I am sure that there were a set of 7 or 8 books in the Dune Story which went through to the end but Audible only have I think four which cover the story. I thought that I read all these books, this long before the follow on from his family. I will not even consider buying or borrowing it from the library.
Unfortunately, as DW gradually took over my bookcase, I donated my Dune collection to a charity shop. I regretted it months later when it was far too late.
