50 Science Fiction Books Ft Via MerchantRD.COM, VIA MERCHANT (8)

Out-of-this-world science fiction books

Science fiction explores both the most wondrous and darkest possibilities of our world. Tracing back to Mary Shelley’s 1818 Frankenstein, the genre has been entertaining readers young and old for more than 200 years. The best sci-fi books ask “what if” questions about our societies, species and existence as a whole. What if an element of today’s society became dangerously exaggerated? What if we had to defend our world against aliens? What if life as we know it isn’t really real?

While science fiction and fantasy books often overlap, sci-fi generally abides by scientific logic, whereas fantasy tends to include elements of magic instead. What some call hard science fiction has a focus on natural sciences like biology, chemistry and astrophysics, while soft science fiction emphasizes social sciences like psychology, politics and sociology. The best sci-fi books, however, blend innovative technological elements with subsequent social ramifications.

We’ve compiled 50 of the best sci-fi books everyone should read, including titles that have remained relevant through the years, books that have been lauded by critics and readers alike, series that have been turned into films and TV shows, and newer page-turners that have created buzz and landed on bestseller lists. Here, you’ll find some of the best books of all time, LGBTQ books, mysteries and classic works of fiction. And of course, no compilation of the best science fiction books would be complete without dystopian books and time travel books to blow your mind.

2. The Left Hand of Darkness by Ursula K. Le Guin

Ursula K. Le Guin was a prolific writer of both sci-fi and fantasy whose long list of accolades includes six Nebula Awards and seven Hugo Awards. Technically, her celebrated 1969 novel, The Left Hand of Darkness, is part of a series called the Hainish Cycle (sometimes called the Novels of Ekumen). While sharing a universe, each book in the series stands alone, so we’re spotlighting this standout story as one of the best sci-fi books ever written. For readers interested in anthropology, philosophy and societal inquiry, Le Guin writes with great depth on themes ahead of her time. Her skillful storytelling brings humanity to the forefront, and her exploration of a planet where gender is fluid challenged the gender norms of the 1960s and remains relevant to gender discussions today. Plus, in a genre saturated with male authors, it’s noteworthy that one of the greats is a female author. For more women authors, check out these feminist books.

3. The Daughter of Doctor Moreau by Silvia Moreno-Garcia

Bestselling author Silvia Moreno-Garcia (you may have read her Mexican Gothic or Velvet Was the Night) brings Latina feminist magic to the literary world yet again, with this 2022 dreamy reimagining of H.G. Wells’s 1896 sci-fi horror classic The Island of Doctor Moreau. Transported to the lush jungles of 1871 Yucatán, readers still get Wells’s mad scientist and his animal-human hybrid experiments, this time from the perspective of his daughter, Carlota, who considers the creatures her family. And while there’s a passionate romance woven into the tale as well, the story also provides commentary on the real-life social inequity and strife present in Mexico at the time. Whether you’ve read the original or not, The Daughter of Doctor Moreau proves that the best sci-fi books can take classic tales to the next level. This is the perfect read for historical fiction lovers and anyone searching for more books by Latinx authors.

17. Drunk on All Your Strange New Words by Eddie Robson

Set in a post-contact, near-future New York City, Drunk on All Your Strange New Words is a 2022 murder mystery in which aliens walk among us and no one bats an eye. These peaceful aliens communicate telepathically, and human interpreters, such as charming protagonist Lydia, must translate what they’re saying into English. But as the title suggests, the caveat is that these interpreters actually get drunk as a side effect of processing the alien language. When Lydia gets accused of murdering one of the aliens and threatening intergalactic peace, she must solve this whodunit to prove her innocence while keeping her wits about her. Robson’s creative world-building and witty dialogue keep the book fun and fast-paced, a welcome break from some of the heavier themes in the sci-fi genre.

Kev wants to protect Ella from the mysterious and growing powers she has. In vivid scenes and searing moments that jump through time, we follow this family story that grapples with systemic racism, loss of innocence and the impossibly hard choices that come with having powers no one else does. At only 176 pages, it’s a short book, but one that will leave you breathless.

42. We Are Satellites by Sarah Pinsker

When it comes to technological advancement, there are three types of people: those who jump at the chance to try the latest, those who reluctantly follow when they feel obligated to adapt and those who wholly reject it altogether. Sarah Pinsker’s We Are Satellites explores the human cost of a brain-enhancing implant from those three perspectives, as well as a fascinating fourth one we don’t often consider. A moving family drama at heart, a sci-fi book like this feels even closer to reality these days, not so much posing a “what if” but an inevitable “when.”

43. Binti by Nnedi Okorafor

The first of the Binti series, Nnedi Okorafor’s 2015 Afrofuturist space novella won multiple prominent literary awards, including the 2016 Hugo Award and the 2016 Nebula Award for Best Novella, and it’s reportedly being adapted into a Hulu television series. The eponymous protagonist is the first of her people on earth to get accepted into a prestigious intergalactic university, and that’s a big deal. “We Himba don’t travel,” she tells readers. “We stay put. Our ancestral land is life; move away from it and you diminish. We even cover our bodies with it. … Here, in the launch port … I was an outsider; I was outside.” While in transit, Binti gets caught in an inter-species war, and she must rely on her courage and intelligence, as well as her people’s ancient practices, to survive.

Space Trilogy By C.s. Lewisvia bookshop.org

44. Space Trilogy by C.S. Lewis

C.S. Lewis is best known for The Chronicles of Narnia, a series of children’s books in the fantasy genre. But his sci-fi work has also been widely read and celebrated. Out of the Silent Planet (1938) marks the first chapter in the author’s Space Trilogy, followed by Perelandra (1943) and That Hideous Strength (1945). In this interplanetary tale of mythological proportions, we follow Dr. Ransom as he explores new worlds. Lewis was more a scholar of theology than science, making some of the scientific possibilities in his work questionable but bringing a depth of thought and meaning that can be rare in the genre.

Light Years From Home Ecomm Via Bookshop.orgvia merchant

45. Light Years from Home by Mike Chen

Mike Chen’s 2022 novel, Light Years from Home, is less about an epic impending intergalactic war—although there’s some of that too—and more about the quiet family drama that ensues when a father and son disappear and then return claiming they were abducted by aliens. Intimate and at times heartbreaking, the character-driven story follows the perspectives of Jakob, who believes the fate of the galaxy rests on his shoulders, and his sisters, Kass and Evie, who cannot agree on whether he’s telling the truth or mentally ill. Don’t expect too much science in this particular sci-fi—it’s light on that. But it does pose the central question that many of the best sci-fi books ask: What would you do?

The Time Machine Ecomm Via Bookshop.orgvia merchant

46. The Time Machine by H.G. Wells

A pioneer of science fiction writing, H.G. Wells wrote sci-fi classics like War of the Worlds and our favorite, The Time Machine. Both were adapted into films, and both have withstood the test of time. The Time Machine was written in 1895 and includes several of the best sci-fi book themes, like out-of-control technology, a dystopian future and post-apocalyptic human conflict. If this appeals to you, pair your reading with one of these time travel movies that will make you question everything.

47. January Fifteenth by Rachel Swirsky

Universal basic income is a hot topic these days, with the argument that all citizens should have the basic right to a livable income. In Nebula Award–winning author Rachel Swirsky’s 2022 novel January Fifteenth, we see this interesting “what if” scenario play out: All Americans get paid on the same day. The book explores the perspectives of different women from different socioeconomic backgrounds—young and old, rich or poor—and offers insight into this alternate world.

At's Cradle By Kurt Vonnegutvia bookshop.org

48. Cat’s Cradle by Kurt Vonnegut

Science fiction fans are divided on whether or not Kurt Vonnegut’s lauded 1963 book fits neatly within the genre, but many critics agree that this is his best work. The post-apocalyptic world of Cat’s Cradle focuses on the decidedly sci-fi conflict of technology and chemical warfare. It’s also darkly humorous and at times absurd, following a first-person narrator who sets out to write about one of the creators of the atomic bomb and ends up interviewing a host of strange characters. The way it tackles themes of not only science but also religion makes it a good pick for fans of satire and cultural criticism.

The Martian By Andy Weirvia merchant

49. The Martian by Andy Weir

This wildly popular 2011 novel was adapted into a movie starring Matt Damon in 2015. Even if you’ve already seen the film, the book is worth a read. Much of its humor and voice come through the journal entries of our protagonist, left for dead on Mars with no companions and few resources. Through ingenuity, hope and sheer will to survive, he must figure out how to be the first human living on Mars. Themes of isolation and resilience are strong, which sounds sobering, but The Martian manages to also be riveting and funny. For anyone interested in space, science and a high-stakes human journey, this book won’t disappoint.
