Not sure if this is the right fit?

Consider Dune by Frank Herbert. Recommended by 30 sources.

“Set on the desert planet Arrakis, Dune immerses you in a feudal interstellar empire where noble houses clash over the universe's most valuable resource. The narrative weaves political intrigue, messianic prophecy, and ecological adaptation. Useful if you want a richly realized world that explores power and human potential. Its density and extensive inner monologue can feel slow; you may find yourself bogged down by the sheer volume of invented terminology and the occasional preachy tone.”
