I'm debating doing the Brian Hebert Dune novels (the 7th and 8th in the series, Frank died after writing the 6th, leaving everybody with a monumental cliffhanger).
BTDT. I'd advise that anyone who loves the Frank Herbert novels should avoid all of the Brian Herbert stuff, most specifically the two novels that claim to adhere to the "Dune 7" notes that Brian supposedly found on a 5.25" floppy among his dad's effects after his death. To accept this "Dune 7" fiction is to accept that all of the Erasmus/Omnius crap Brian Herbert and Kevin Anderson spewed out in the prequel novels had already been forethought by Frank. There's not enough storage space on a 5.25" floppy for all of the crap Brian created.Duncan Idaho is the "true" Kwisatz Haderach and can imagine/will things into or out of existence? Puh-fargin-leeze.
That said, I slavishly read all of the prequel and "Dune 7" mess hoping that some kernel of Frank would peer out from behind the dreck. Never happened and I've not read any of the stuff he's put out after the "Dune 7" duology. Of course, this is coming from someone who devoutly wishes that the Dune Encyclopedia
had not been made non-canon by the abominations spewed out by Brian Herbert & Kevin Anderson. The revised version of how the Atredies/Harkkonen feud started is a simpering and callous chickenout compared to the Dune Encyclopedia, not to mention how the need for publishing revenue completely threw out the Encyclopedia version of the Butlerian Jihad for the story seen in the prequels.
Yes, I have strong feelings about the Dune universe. The Encyclopedia was canon to Frank, thus it's canon to me. Omnius, Erasmus, and the Titans can just bugger off.
Science IS NOT TRUTH. It is an iterative process asymptotically coming ever closer to Truth, but destined never to arrive there.
