"Dystopias, alien invasions, regenerated dinosaurs, space operas, multiverses, and more, the realm of science fiction takes readers out of this world to tackle all-too-real issues, including oppression, bigotry, censorship, and the horrors of war. To celebrate the most inventive of genres, we're exploring readers' 100 most popular science fiction novels of all time on Goodreads.
As all good sci-fi readers know, the science behind the story is half the fun. To create our list, we ran the data to reveal the most reviewed books on our site. Additionally, each title needed at least a 3.5-star rating from your fellow readers to join this list. And, since science fiction is known for its continuing voyages, in the case of multiple titles from the same series, we chose the one with the most reviews."
