i know we're talking a lot about themes and about the 4th book, but can someone help me understand Children of Dune? specifically the plot
what the FUCK were all the various schemes in this book? ive reread most of the relevant chapters and i cannot fucking figure out exactly what all the various players were plotting other than Leto and Ghanima. Herbert did an excellent job setting up all the players but in the end Leto just dunks all over them. what the fuck were the motivations/end plots of
>Jessica/Gurney
>Alia
>Duncan Idaho
>The Preacher/Paul
>Farad'n
>Bene Gesserit

As i said we know Leto/Ghani. Stilgar doesnt really have any plans, same with Irulan. It's difficult because it seems like so many characters already know what the other players' plans ARE but can never state them, and instead Herbert writes around that and confuses a poor retard like me
