It has taken me many years to get around to reading the series as I am a slow reader and have not had the time to sit and absorb them. I have been engrossed in them and find it difficult to wait between completing each book before I start the next. Dune the best, I however am enjoying them more the further into them that I get. I am waiting in anticipation to see what happens in Chapter House. I agree with some other comments - Paul Atraides is not the only interesting person in this series, there are many.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing.
