Le Guin, the propulsive problem-solving of Andy Weir, or the unsettling prescience of Philip K. Dick, sci-fi at its best makes you think differently about the world you already live in.

This list ranks the best sci-fi books using our scoring algorithm, blending reader review data with rating volume to surface the titles that have earned lasting acclaim.
