Finished Dune books 1 to 6 - all those by Frank Herbert.
I'm a little annoyed that it ends on a cliffhanger 😅
I know his son carried on the saga but I don't want to keep going - his son's forewords before each book were annoying enough, sometimes even giving spoilers while fawning over his father!
It was a good long saga though. First one the best of course, some got a bit long winded and super weird, the last two were interesting and different, written from another perspective.
