Dune Prophecy.
Taking place over a thousand years before Paul Atreides, this is the story of the rise of the Bene Gesserit order as a political power at the hands of two Harkonen sisters, and how they plan to breed the universe' superbeing. Intrigue includes the emperor and his daughter who's been married into a political marriage with a nine year old(!), as well as an imperial veteran who had been the sole survivor of a battle on Arrakis, and who seems to have machinations of his own that include the sandworms.
So far, it's capture my attention.
