What "Lord of the Rings" is to fantasy, "Dune" is to science fiction. An absolute masterpiece! Methodical... complex... deep... fascinating... awesome! A blend of action, politics, mysticism, ecology and economics... with witches, tyrants, uber-men, sabotage, visions and a vastness that you can meditate on and reference for the rest of your life. One of the greatest books of all time. "The spice must flow."
