20 Best Sci-Fi Books of All Time 23

If you are looking for the best sci-fi books of all time, you have come to the right place. We do not always read science fiction books so when we do, it is usually the best of the best. Classic science fiction books like the ones below have been pivotal in literature curriculums for good reason.

Themes like space travel, time travel, and gene manipulation run through these books and were once just fiction. It makes me wonder where we will be in 50 years and if all the themes in these books will still be just fiction or if time travel may become reality.

klara and the sun

Klara and the Sun by Kazuo Ishiguro

the martian

The Martian by Andy Weir

This sci-fi book was the inspiration for the movie starring Matt Damon. The movie was fantastic. It will not surprise you to hear that the book was better.

There was no question that this book belongs on a list of the best sci-fi books of all time. When Mark Watney becomes trapped on Mars after a dust storm, he has no way to communicate that he is still alive. He has to use his brains, quick thinking, and ingenuity to overcome one obstacle after another and stay alive.


Dune by Frank Herbert

I read this sci-fi book after I watched the first movie. The movie was surprisingly true to the first half of the book and I cannot wait to see the second movie.

twenty thousand years in the future, humans live on multiple planets. The most important substance is called Spice. It is a psychedelic substance that is the only thing that allows for space travel and it is found in only one place, Dune. As forces fight for control of Spice, they are also fighting for existence and continuing their way of life. This is the first in a series of six books

in the lives of puppets

In the Lives of Puppets by T.J Klune

Let’s be honest, I would read anything that TJ Klune writes. House on the Cerulean Sea was my Best Book of 2020 and Under the Whispering Door was my Best of 2021. It is safe to say that you will find this book from the list of spring 2023 book releases on a best-of-post!

In a forest, safe and hidden, live a human and three robots. When an unfamiliar android reveals a dark shared past of hunting humans, they are no longer safe. This book is a lot sadder than Klune’s other adult books but has his signature sense of humanity in this sci-fi book.

cloud cuckoo

Cloud Cuckoo Land by Anthony Doerr

I don’t know how to begin to describe this book. This is NOTHING like All The Light We Cannot See and yet, I absolutely loved it. It is part historical fiction, part sci-fi, and absolutely amazing.

The book is set in Constantinople in the fifteenth century, Five hundred years later in a library in Idaho and in a spaceship traveling to a new planet sometime in the near future. Even while trying to describe this book, it does not seem to go together and yet, the story of Cloud Cuckoo Land (a story within the Novel) acts as the glue that brings the characters together. The end result is an amazing sci-fi book with a very powerful message.

This is not an easy read but is well worth it.

The Husbands

The Husbands by Holly Gramazio

April 2024 Read with Jenna Book Club Pick

Think of this book as Sci-Fi lite. It calls upon sci-fi-based principles – mainly multiverses – but it doesn’t dwell on the scientific for even a moment.

The premise is simple. Lauren, a single woman, comes home one night to a husband she didn’t know she had. Her phone, friends, and photos in her apartment reflect this new life but she can’t remember it. And then something crazy happens.

He goes up to the attic to change a lightbulb and a new husband descends from the attic. Whenever a new husband emerges, the life around her shifts again. So with an endless supply of husbands, she finds herself torn between knowing when to send them back and when to keep one and start living.

Why I Loved It: Easily one of the most unique plots I’ve ever read. Even as a confirmed disliker of Sci-Fi books, I found this story compulsively readable. I had a blast watching Lauren try to figure out her life and the revolving door of husbands had me giggling at times. #gifted by PRH Audio

The Echo Wife

The Echo Wife by Sarah Gailey

I picked up this sci-fi psychological thriller because of the cover (#booktruth.) I thought it would be about a first wife upset that she had been replaced by a trophy wife…little did I know, she was replaced by a LITERAL CLONE of herself.

I’m not usually into sci-fi, that’s firmly Jackie territory, but it was actually pretty good! If you like Sci-Fi, you would probably REALLY enjoy it. It was clever and interesting, even if it’s not my usual cup of tea.

Fahrenheit 451

Fahrenheit 451 by Ray Bradbury

Bradbury’s dystopian classic is one of the most well-known pieces of modern literature but I hadn’t read it! I don’t usually gravitate to books like this, but I had heard so many people speak about the relevancy of this novel today.

It’s so true. This sci-fi book offers a grim look at our future if our society continues down the road of this technology obsession we seem to have. If you liked 1984 or The Circle, you will devour this book.

with regrets

With Regrets by Lee Kelly

This sci-fi book is funny, scary, and poignant – a true genre-defying work of fiction unlike any other! It’s a dystopian thriller about a dinner party in a wealthy area that coincides with the dawn of a dystopian apocalypse.

When Liz begrudgingly goes to influence Britta’s dinner party, the last thing she expects is the glimmer – a strange sparkling cloud that kills everything it comes in contact with. Now Liz needs to find a way to survive the evening in a completely different way than she expected.

I was completely immersed in this novel. I didn’t want to put it down, though it did have me wondering if I could in fact survive the apocalypse. #gifted By Dreamscape Media

Vox by Christina Dalcher

Once I got into this sci-fi book /fantasy novel, I could not put it down. The story takes place in the United States when a fundamentalist has become the president. Slowly, he has removed all rights from women, including the right to speech.

Every woman is given 100 words a day and a bracelet with a counter to ensure compliance. This book was so well-written and creepy. I loved it although I have to say that it was a little close to how I feel these days
