The Best Modern Sci-Fi Books

Make sure you own a copy of these must-read modern sci-fi masterpieces.

By Josh Tyler | Updated

Any discussion of the best sci-fi books invariably begins and ends with the masters of the sci-fi genre. Jules Verne, Isaac Asimov, Robert A. Heinlein, Phillip K. Dick, Arthur C. Clarke, Ray Bradbury, H.G. Wells, Frank Herbert, Jerry Pournelle, and so on.

What do all of those authors have in common besides their sci-fi prowess? They all did their most significant work before 1980. Ironic for a genre that’s so much about the future, much discussion of the best sci-fi books seems to center around things written in the distant past.

People didn’t suddenly stop writing sci-fi books in 1980. In the past thirty years a new group of sci-fi authors has risen to make their mark on the genre, with their own masterpiece entries.

This list is dedicated to those book authors, the modern sci-fi masters who are only beginning to take their place in the pantheon of sci-fi icons. If you’re serious about sci-fi, or just looking for a great book to read without all the baggage of something written in a long since bygone era, make sure you own a copy of these modern must-read sci-fi books.

The Expanse | published 2011 – 2020

The Expanse sci-fi novels

Books Written by: James S.A. Corey

James S.A. Corey is a pen name used by two different writers, Daniel Abraham and Ty Frack, working in collaboration. The Expanse itself is the broader name of a series of sci-fi books about a near future where mankind has colonized the solar system and faces political and population pressure to reach out into the stars.

Each book in The Expanse series follows primarily a character named James Holden, but also mixes in other characters, in a journey with a focus that changes from one book to the next. The first book plays out in parts like a zombie movie, the next feels almost like a more grounded take on Han Solo and his crew in the Millenium Falcon.

What really sets The Expanse apart is the way it explores human nature and human politics and the way in which it applies scientific realism to the outer space world it inhabits. If humanity ever does spread out beyond Earth’s atmosphere, you can bet it will look almost exactly like everything in The Expanse books.

The Expanse has also become an excellent television show, which currently finds a home on Amazon Prime. Even though the show is really good, it’s still not as good as the books. Make sure you both read and watch The Expanse.

Old Man’s War | published 2006

Old Man's War sci-fi book

Book Written by: John Scalzi

In Old Man’s War the elderly are sent to space and given new bodies to fight battles against encroaching aliens.  The war itself is enough of a draw, harkening back to the world of Heinlein’s Starship Troopers. But the concept behind what sends our hero there is what really puts this book over the top. 

Old Man’s War ends up being both a meditation on the brutality of humanity and also on aging. In it’s best moments it reminds me of both Starship Troopers and Wrath of Khan and maybe Cocoon too all rolled into one. 

The story follows an officer named John Perry and it’s an adventure story first, so don’t worry about getting bogged down in all those high-minded concepts.  But Scalzi weaves his ideas effortlessly into a confident, easy-to-read narrative. Old Man’s War is a fantastic sci-fi book.

The Commonwealth Saga | published 2002 – 2010

Commonwealth Sci-Fi Novel

Books Written By: Peter F. Hamilton

The Commonwealth Saga encompasses a wide range of sci-fi books written by Peter F. Hamilton and set in the same universe. Some of them connect narratively and some of them have no connection at all other than existing in the same realm. They’re all worth reading, as Hamilton approaches sci-fi from a unique perspective which is almost more of a philosophy than a style of writing.

Hamilton’s sci-fi books, all of them in one way or another, consider what humanity could or may become, by propelling readers into a future as far off from our here and now as we are from the worlds of King Arthur. That may sound daunting, but Hamilton turns it into an adventure where we explore not just what we will be but what we can be.

If you’re looking for a starting place to enter Hamilton’s world, I’d recommend beginning with Pandora’s Star and its direct sequel Judas Unchained. Those two books form one, single narrative which kicks off when humanity suddenly invents instantaneous teleportation. Walk through the doorway with Hamilton and have your entire view of humanity changed by it.

The Dark Tower Series | published 1982 – 2004

Sci-Fi Novel The Gunslinger

Books Written by: Stephen King

Stephen King is best known as one of the modern masters of fantasy and horror but The Dark Tower series is as much a series of sci-fi books as they are anything.

It all started with the publishing of The Gunslinger in 1982, a story that opens with these unforgettable words…

“The man in black fled across the desert and the gunslinger followed.”

– The Gunslinger by Stephen King

He followed through seven epic books on a journey across dimensions and time and space.

The gunslinger is named Roland and he’s a cowboy, sort of, from a dimension that is sort of like our medieval past merged with a Clint Eastwood movie. His world was destroyed by an evil force, and he’s on a mission to find a mythical place called the Dark Tower, which he believes is at the nexus of everything. He picks up companions along the way, and they develop a relationship with each other (and in the process the reader) that goes beyond mere words.

Filled with violence and misery, and heart-wrenching beauty and joy, it’s one of the most emotionally moving sci-fi book series’ on this list. Read all seven books, skip the terrible Dark Tower movie that got made out of them, and say thankee-sai.

The Liaden Universe | published 1988 – 2010

Sci-Fi Novel Agent of Change

Books Written by: Sharon Lee & Steve Miller

Agent of Change was the first sci-fi book published (though not the first chronologically) in what would eventually become known as the Liaden Universe. The series contains nine sci-fi books in all, all set in the same fictional future, but each book is completely different from the other.

Agent of Change, for instance, is an intimate spy novel focused on a small handful of characters engaged in a complex game of cat and mouse, set on a single planet. Balance of Trade, my favorite of the series, is the story of the crew aboard a massive, intergalactic merchant ship, making their way from one planet to the next.

Others are romance novels and political thrillers, all set in the same fictional world. Best of all, it somehow all fits together. They aren’t random stories but larger parts of the same whole, each told in their own way and from their own angle.

Hyperion Cantos | published 1989 – 1997

Sci-Fi Novel Hyperion

Books Written by: Dan Simmons

The Hyperion Cantos is actually four sci-fi books. The first two, Hyperion and The Fall of Hyperion tell one part of the story. The second two, Endymion and The Rise of Endymion tell a completely different part. Together they form one, contiguous whole, the story of a future where man believes he has conquered the universe, but really hasn’t.

It starts with the story of a few pilgrims, journeying to a strange planet called Hyperion. There they’ll encounter an impossible and seemingly all-powerful being called The Shrike, who captures travelers and impales them on his tree of pain (which is every bit as horrible as it sounds).

Rarely has anything more thoughtful, imaginative, and emotionally wrenching ever been written, outside of sci-fi or in it. Dan Simmons’s story challenges the very nature of humanity and the universe while delivering serious sci-fi adventure.

On Basilisk Station | published 1992

Honor Harrington sci-fi book

Book Written by: David Weber

On Basilisk Station is the first sci-fi book in author David Weber’s expansive Honorverse series, but I’m not going to recommend the entire series. Start with just this one book and stop reading them when it feels like you’re done with the series.

The first book is the best of the bunch and the quality dwindles as the series goes on, but that’s fine, because On Basilisk Station works even as a standalone novel.

It’s a space opera about a female military commander named Honor Harrington and her ship, the Fearless on assignment, and in the heat of battle in a remote part of space where they’re the last line of defense against invasion.

Weber’s depiction of Honor is one of the strongest female literary characters you’re likely to encounter anywhere, and his detailed yet entertaining grasp of strategy and tactics used in outer space is unmatched.

The Time Ships | published 1995

Sci-Fi sequel to Time Machine

Book Written by: Stephen Baxter

In The Time Ships, a critically acclaimed follow-up sci-fi book authorized by the H.G. Wells estate to mark the 100th anniversary of The Time Machine, British author Stephen Baxter explores the paradox unwittingly created by the original story.

Picking up where the Wells classic leaves off, the Time Traveler returns to the future to save the girl he left to die at the hands of the Morlocks. Along the way, he notices that time has changed.

He stops to investigate and learns that he’s polluted the timeline and that the future he left never existed. In trying to repair the timeline, he only makes it worse, even to the point of threatening his very existence and that of the human race.

It’s a complex, thought-provoking adventure in true Wells tradition, questioning the moral obligations to one’s future and past. Baxter seamlessly slips into a nineteenth-century “Wellsian” writing style while remaining as relevant to modern steampunk audiences as to fans of the classic Wells.

A Deepness in the Sky | published 1999

Modern sci-fi master Vernor Vinge

Book Written by: Vernor Vinge

You can’t really go wrong with any of the books in Vernor Vinge’s “Zones of Thought” series and most people would probably put the older A Fire Upon the Deep here, but I’ve always been partial to Deepness. Both sci-fi books are standalone novels, despite being set in the same universe, so pick either one and you can’t go wrong.

A Deepness in the Sky is the story of what happens when an intelligent alien species is discovered on a planet orbiting around an anomalous star which causes their entire race to go dormant for long periods of time every couple hundred years. The story’s told both from the perspective of the humans in orbit, and from the perspective of the alien species as they prepare for their planet’s big freeze.

It’s a great story, but it’s particularly noteworthy for its complex depiction of a completely alien species, the best I’ve read since The Mote in God’s Eye. Vinge’s approach is, however, completely different than the one used by Niven and Pournelle in Mote, instead, he attempts to translate their completely alien thoughts and life into human terms… and it works.

Ready Player One | published 2011

ready player one sci-fi novel

Book Written by: Ernest Cline

This is the sci-fi book that defines modern geek culture, and the impact of video games on our world. Although author Ernest Cline goes far beyond just extolling the greatness of classic video games, it’s within a virtual world that we get to love the oldies once again.

Told from the perspective of an 18-year-old generic everyman, Wade Watts is a kid who lives in a crime-infested trailer park. He spends most of his time hiding out in a junkyard jacked into a school computer where he attends classes virtually.

The novel mostly takes place within the virtual world of THE OASIS, a game that becomes so pervasive by the start of the novel in 2044 that it’s not just an online world but is really the whole Internet. Good versus evil, geek references to everything from Gundam to Ghostbusters, and a healthy dose of intrigue and action make Ready Player One not only a good bit of fun but also this decade’s must read sci-fi novel.

The sci-fi book has also been turned into a sci-fi movie of medium quality. The movie did well enough but the book is more culturally relevant. People are still reading the book, and the movie version of Ready Player One is already all but forgotten.

Jurassic Park | published 1990

Jurassic Park sci-fi book

Book Written by: Michael Crichton

Long since eclipsed by the still great 1992 Steven Spielberg based on it, Michael Crichton’s original novel is still worth a read. It’s by far the best work the rockstar-level famous author has ever done and, if you read it you can seem smart in front of your friends when they’re talking about the movie.

The plot actually deviates from the movie in some pretty key places, though it’s still about a billionaire who builds a park with live dinosaurs in it, which invariably goes wrong when “nature finds a way”. All the familiar characters are there, but the whole thing gets taken even further, beyond the special effects budget of even a Spielberg movie.

Crichton’s sci-fi book is far more dark and more dire than the film too, filled with even more violence and a lot more things blowing up. Spielberg’s movie is the better version I suppose, but Crichton’s book is good enough to be worth a read in its own right.

It’s a cultural touchstone that deserves its place in the pantheon of iconic modern science fiction.

Neuromancer | published 1984

Sci-Fi Book Neuromancer

Book Written By: William Gibson

William Gibson created the cyberpunk genre with Neuromancer. A story about a dystopian future where Henry Case is caught as a thief has his brain interface with the virtual reality world of the “Matrix” removed and is now a drug addict desperate to find a cure for his problems.

What follows is a story of hackers going to battle, the effects of technology on mankind, and an exploration of what exactly defines reality.

What really matters in geek culture is that Gibson developed the notion of the cyberpunk world with this sci-fi book. The idea of AI constructs taking on humans, technology as a drug, and virtual worlds where battles can occur, are all either originated or defined clearly within Neuromancer.

The novel also established the noir tonal quality of the genre. Of course, Neuromancer is most known as the blueprint for The Matrix, but has always been regarded as a seminal work in the sci-fi world.

Ender’s Game | published 1985

Ender's Game sci-fi book

Book Written by: Orson Scott Card

There’s never been anything quite like Ender’s Game, before or since. Not even the sequels. Orson Scott Card’s masterpiece tells the story of young children whisked away to a battle school for gifted minds where humanity hopes they’ll be able to transform one of them into the military genius the world needs to save them from an impending alien invasion.

It’s about kids but it’s not a sci-fi book for kids. What happens in that battle school is brutal and brilliant, full of strategic thinking and mind games played the way they can only really be played amongst untested genius intellects.

In the end, all the kids involved are left warped, changed, and screwed up, but none worse than Ender. In a sense, Ender’s Game is about how saving the human race ruined one little boy’s life.

There’s a science fiction movie version of the book and while it didn’t do well at the box office, it’s pretty good. The book is much better though. Read the sci-fi novel before you bother with the Harrison Ford film.
