“He who controls the spice controls the universe.” With another re-invention, both Arrakis and God Emperor of Dune fling the reader into world's unknown. Set thousands of years after Children of Dune the fourth novel in the series reads fresh from the rest. There's a literal sandworm-human hybrid, the only sandworm left on Arrakis, controlling all source of spice. Much of this book deals with the new religion spawned from this much control. The debate about what constitutes a God is frequent. Plenty of new memorable characters get introduced and have their arcs, as well as a sprinkle of old favourites. This new Arrakis is fresh and appropachable. Get sucked into the worm god.
