Dune

I've read dune up to where Herbert left off, should i read the two sequels written by his son or should i stop here? I've heard that they where pretty horrible.

KJA & BH are not that good together. It's unfortunate, but the Dune series died with Frank. I also want to know how the series 'ends'.

Have you check out any of Frank Herbert's other books or short stories? All very far and topical like Dune.
