"I have never listened to anyone who criticized my taste in space travel, sideshows or gorillas. When this occurs, I pack up my dinosaurs and leave the room."

-Ray Bradbury

Don't pack up your dinosaurs, fellow sci-fi readers. You're among friends here.When we set out to uncover the top science fiction books on Goodreads, our journey—searching through hundreds of books and thousands of ratings and reviews—was a spacewalk down memory lane, from revisiting the sci-fi heroes we grew up with, like young brainiac Ender and hapless (and homeless) Arthur Dent, to returning to beloved worlds created by Ursula K. Le Guin Octavia Butler , and many more.The bar needed to be high. Every book on our list has at least a four-star average rating from Goodreads members. Unfortunately, this means that dinosaur king himself Michael Crichton failed to make the cut, along with other big names in the genre like Kim Stanley Robinson William Gibson , and H.G. Wells . But while some classics may be missing, recent favorites from Emily St. John Mandel Nnedi Okorafor , and Pierce Brown round out the list.Without further ado, let's boldly go where many readers have gone before. Tell us how many of the top 50 sci-fi books you've read in the comments!
