Set on the desert planet Arrakis, "Dune" is a landmark science fiction novel by Frank Herbert. The story is centered on Paul Atreides, whose noble family is tasked with ruling the inhospitable world. Arrakis is the sole source of "melange," or "spice," a valuable drug that extends life and enhances consciousness, leading to political conflict among the noble houses. The narrative follows Paul's transformation after his family is betrayed, as he and his mother, Lady Jessica, escape and seek refuge with the Fremen, the planet's native inhabitants. Paul eventually becomes a powerful leader and prophet to the Fremen, leading them in a revolution and ultimately challenging the Emperor for control of the universe. The novel explores themes of ecology, religion, politics, and human evolution.
