This was hard-going from reading a lot of Dune in a few months. It took me a while to get into this one and get the hang of the plot. Generally I'd say every Dune since the first one, I struggle to work out the politics of it.

Then it got going and I quite enjoyed it, reasonably full of action. And then the Bene Gesserit ("good") and the Honored Matres ("bad") just get creepier and creepier with the sex-to-control-men thing. It's been building for a few books, but, to me, it feels like something someone writes to justify why they hate women. There are few named women in this that aren't a secret society using sex or breeding to control everyone else.

On a lighter note, towards the end, there is an impromptu sex fight between a man and a woman while others watch, where the person who orgasms is the loser of sex fight. I don't think it's supposed to be funny, but I laughed a lot.
