Brian Herbert and Kevin J Anderson are writing prequels to the original Dune sextet, and after they finish those, there will be a two part Dune 7, based on Frank Herbert's notes for the next(final?) Dune novel. So far, I have read House Atreides and House Harkonnen. I started The Butlerian Jihad yesterday, and bought a copy of House Corrino to read after that. By the time I finish those, The Rise of the Machines should be out in paperback, and shortly after that, The Battle of Corrin will be available in hardback. For those of you reading the novels, what is your impression of them, compared to the original six?
