So, Dune. Galaxy of weird religious zealots, sandworms, and shields that nuke you if you laser them.
Also Spice, of course.
It has 8 (6 +2) books. Discuss.
Infidel. It has six books, and the number of the books shall be six. No more, no less. Neither shalt thou count seven, nor five, unless after the counting of Heretics, thou proceedest directly to Chapterhouse. Eight is right out.
Seriously, I wish ghola technology existed so that we could resurrect Frank Herbert to do two things:
1. Keep writing more books.
2. Beat the living shit out of his son until he swears not to write anything ever again.
I think Children is probably my favorite of the series, and perhaps the best written. But I love all of them. The last two get very complicated and suffer from the classic "old man writer's malady" (i.e. too much preoccupation with sex), but they are awesome in their own ways.
One thing that Herbert is notorious for (and at the same time, which endears much of the series to me) is his creation and use of 'munchkin' characters. Paul is not only the well-trained son of an Imperial Duke, he's received secret Bene Genesserit prana-bindu training, *and* Ginaz swordmaster training *and* he's become a Fremen *and* he takes the Water of Life and becomes damn-near omniscient. Later on, Murbella becomes the leader of the Honored Matres and the leader of the Bene Gesserit about thirty seconds apart (the former by killing the previous leader, the latter by inheritance from the dying Reverend Mother Superior).
If Frank Herbert played D&D, all his characters would be lvl 36 fighter/mage/thief/clerics/ranger/druid/monks. With maxed stats. But he managed to do it in a way that made sense in-universe. Brian Herbert took that trick, amped it up to 11, and generally explained it with a total ass pull.
