Discover the 20 Best Sci-Fi Books of All Time

Science fiction is one of the most popular and well-recognized literary genres of all time. Although there is much speculation about when and where the genre originated, most critics consider Mary Shelley’s famous 1818 novel, Frankenstein as the first influential sci-fi novel. Although this book predominantly tackles themes of companionship, humanity, nature, and love, the novel also propelled topics like scientific experimentation and body disfiguration into the literary mainstream. 

During the 19th century, science fiction really took off, allowing canonical authors such as H.G. Wells, Jules Verne, and Robert Louis Stevenson the space to experiment with new, scientific concepts and configure brilliant stories around them. 

Now, science fiction is one of the most well-read and adored literary genres out there and with the help of film and television for visual aid, sci-fi stories are reaching new audiences every day. 

Whether you’re a hard-core sci-fi fan or you’re just looking to dip your toe into this exciting genre, here’s an ultimate list of the 20 best sci-fi novels of all time.

Dune by Frank Herbert


Chances are you’ve seen images of Timotheé Chalamet and Zendaya’s film adaptations dotted around social media platforms or billboards but you may not have taken the time to read Herbert’s original work. Although the films are great, this book is unmatched. There’s a reason they’re among the highest-selling books of all time!

Although the film involves lots of fast-paced chase scenes and tension, the Jurassic Park novel delves into behind-the-scenes details that bring the story to life even more. 

The Martian by Andy Weir

If you’re looking for a well-written, accessible, thought-provoking read, look no further.

A Clockwork Orange by Anthony Burgess

A Clockwork Orange

A Clockwork Orange is often grouped with dystopian fiction and for good reason. However, Burgess’s use of futuristic perspective, psychology, and the scientific undertones that run throughout allow this novel to float between dystopian and science fiction genres.

This story follows Alex, a rebellious teenager who is forced to receive treatment at a psychological rehabilitation center. It’s an interesting and well-constructed criticism of political authority and will spark conversation about human liberty and the fine line between right and wrong.

He is sent to Winter, an alien planet that is attempting to build an intergalactic civilization that defies the social standards established on Earth.
