Space Opera

Stories that take place on an interplanetary scale.

Dune by Frank Herbert

A dense, and complex, space opera.  Set in the far future, when humanity has spread across the stars, Dune immerses you in a vast galaxy full of intricate cultures and political intrigue. The novel also asks you to consider themes of predestination, religion, politics and basic human nature.

Herbert’s descriptions of the desert planet of Arrakis, the Fremen who populate it and their culture and the sandworms have become a part of science fiction heritage. The novel won the Hugo award in its year of publication and is often cited as the best science fiction novel of all time.

Hyperion by Dan Simmons

Seven pilgrims all journey together to the mysterious planet of Hyperion. During their journey, each pilgrim tells the others their story. As they do, a vast universe opens up to the reader. Each story is written in the style of a different subgenre of science fiction. This makes Hyperion multiple science fiction novels in one. If this sounds interesting to you, you might be interested in our full review of Hyperion.



Revelation Space by Alastair Reynolds

A space opera with a dash of biopunk. Revelation Space is gritty, brutal and awe-inspiring. The plot contains an archaeological dig on an alien planet, mercenaries travelling across space in light-hugger spaceships, and humans so altered they are almost indistinguishable from aliens.




Ancillary Justice

The groundbreaking and multi award winning debut from Anne Leckie, is the undoubtedly one of the most interesting space operas ever written.

The novel is follows Breq, the last remnant (or ancillary) of an an intelligent ship called Justice-Of-Toren. Breq, she is wandering the galaxy seeking revenge on a being who cannot die. The story spans worlds and thousands of years, yet despite it’s epic scale is also a touching human novel about broken people. You can read our review and analysis here.

Science fiction novels that involve high tech, low lives and a lot of bitter rage. 

Neuromancer by William Gibson
Molly Millions Neuromancer

A book that both defined the Cyberpunk genre and broke science fiction conventions. Neuromancer is gut-punch of a book that takes the reader on a tour of a dystopian future that will make your eyes bleed. But in a good way. It’s no understatement to say that reading this book will change you. You can see our full review of this science fiction masterpiece here.



Snow Crash by Neal Stephenson

So cool it called its Hero Protagonist ‘Hiro Protagonist’. Perhaps the only book ever to mix Sumerian mythology with virtual reality. Snow Crash is truly Cyberpunk, with our hero having to navigate a brutal fast-paced society to stop a corporation and save the world. Possibly the most awesome book you will ever read.

Snowcrash is a beautiful mess of a novel full of hackers, killers, and Sumerian myths. If that sounds bizarre, trust me, the reality is weirder. The virtual reality ‘metaverse’ in Snow Crash provides much of the books wow factor. If this intrigues you, you can read all about why Snow Crash is such an awesome book in this review.


The Stars My Destination by Alfred Bester

Perhaps the original Cyberpunk classic. Bester’s The Stars My Destination re-imagined the Count of Monte Christo in a truly terrifying way. It’s ‘star’ is the terrible and terrifying Gully Foyle. A man inspired by hate and driven by vengeance. The Stars My Destination forces you to view humanity in a different light. You can read our full review of The Stars My Destination here.

Artificial Intelligence Science Fiction

Science fiction novels that focus on the implications of artificial intelligence.

I, Robot by Issac Asimov

Do not be put off by the rubbish Will Smith film that this collection of short stories inspired. I, Robot was one of the first science fiction novels I read and one I would still recommend to anyone.

It was in one of these short stories, Runaround, that the three laws of robotics were codified and it’s still a must-read for anyone wanted to delve into the world of artificial intelligence science fiction.


Do Androids Dream of Electric Sheep? by Philip K Dick.

This book is very different from the film it inspired and deserves to be considered a classic in its own right. Perhaps even more melancholic than Blade Runner, Do Androids Dream Of Electric Sheep is a beautiful novel full of broken things. As we follow Rick Deckard’s attempts to kill androids we can’t help but wonder what it means to be human. As with all of Philip K Dick’s work, Do Android’s Dream of Electic Sheep is unsettling and thought-provoking in equal measure.



The Diamond Age: Or, A Young Lady’s Illustrated Primer

Neal Stephenson is not a writer to create a novel that looks at just one theme so, fittingly, The Diamond Age considers topics such as education, class and artificial intelligence. This is all set in a world where nanotechnology has run rampant. Stephenson’s style is not for everyone, but those who love it really love it.

Science Fiction Comedies

The funniest science fiction novels we’ve read.

Hitchhiker’s Guide to the Galaxy by Douglas Adams

The one book we can confidently say everybody in the galaxy should read. Hitchhiker’s Guide to the Galaxy is a science fiction classic and has entered the cultural zeitgeist. Characters like Ford Prefect, Zaphod Beeblebrox, Arthur Dent and, of course, Marvin the paranoid android are some of the weirdest and funniest ever committed to print.




Slaughterhouse-Five by Kurt Vonnegut

It’s not a comedy in the same way Hitchhikers Guide to the Galaxy and Martians Go Home are, but it’s darkly funny in its own tragic way. Slaughterhouse-Five deals with the British bombing of Dresden, which was witnessed by Vonnegut. That it’s also a humorous non-linear classic science fiction novel gives you an idea of Vonnegut’s genius.




Martians Go Home by Frederic Brown

The Martians have invaded and, unfortunately, they’re jerks. Earth finds itself home to billions of wise-cracking Martians. They’re not so much interested in invading as they are getting in the way and making a nuisance of themselves. It’s a humorous classic science fiction novel for anyone who liked Mars Attacks!

You can read our review of this novel here.




Soft science fiction

Science fiction that focus more on character and concepts than it does actual science. 

Odd John by Olaf Stapledon

Odd John considers how the next step in human evolution would view its predecessors, i.e us. We may not be comfortable with the answer. Odd John is a challenging novel from one of science fiction’s great philosophers. You can find a fuller analysis of Odd John here.





Gateway by Frederick Pohl

Gateway takes place in a grim version of humanity’s future. The rich have almost perfect health due to expensive healthcare, but the poor live short brutish lives in mines.

Far above this divided Earth hangs an alien space station built into an asteroid and filled with working ships. The space station and ships having been abandoned by an advanced race called the Heechee. The novel is told through one of the prospectors who did manage to strike it rich: Robinette Broadhead. It’s a brooding novel, in which the pressure builds as much on the reader as it does on Robinette.  Gateway is a tense read, but a truly compelling one.


A Canticle For Leibowitz by Walter M. Miller.

Possibly the most ambitious first novels ever written. A Canticle For Leibowitz begins in the ashes of a post-nuclear war earth and spans 1000s of years. The story follows an order of Catholic Monks, who’ve vowed to preserve knowledge for eternity. By following the order we see the interplay of religion and scientific endeavour. And, perhaps more pertinently, what happens when the scientific endeavour is not coupled with a moral compass.



Lathe of Heaven by Ursula K Le Guin.

This strange novel is a work that readers will come back to repeatedly in the search for greater understanding. The plot of the novel revolves around George Orr, whose dreams can rewrite reality. While George is happy to suppress his ability, his court-appointed psychiatrist Dr Haber forces him to exploit it. This classic work of science fiction explores both behaviourism and utilitarianism, all in a compelling and mysterious narrative.

We discussed the theme of passivity in our review of The Lathe Of Heaven.



Flowers For Algernon by Daniel Keyes

Flowers For Algernon will be loved by successive generations until the sun dies. Our narrator, Charlie Gordon, has his intelligence raised from 68 to genius levels with the help of an experimental procedure. Unfortunately his new found intelligence does not lead to greater happiness. Flowers for Algernon raises many ethical questions with its simple, heartbreaking plot. You can read our review and analysis of Flowers for Algernon here.



Hard science fiction

Novels where the drama is bound by strict scientific rules.

Ringworld by Larry Niven

RRingworld book coveringworld’s follows the permanently bored 200-year-old Louis Wu, the genetically lucky Teela Brown, and two very different aliens as they travel to a giant object deep in space.

The novel is a thought experiment that details alien architectures and cultures with scientific detail. I’m not sure it’s possible for travel writing to meet hard science fiction but, if it is, Ringworld manages it.



Inverted World by Christoper Priest

Any novel that opens with the line  “I had reached the age of six hundred and fifty miles.” has to be worth a read.

Inverted World takes place in a city that is constantly being moved in an attempt to reach something called the ‘Optimum’ while they hope for a rescue mission from the planet Earth.  It’s an intense read, full of mystery, that will ask you to rethink any preconceptions you may have. You can read a further analysis of this novel here.



Rendevous with Rama, by Arthur C Clarke

A hard science fiction novel where the sense of wonder comes very much from the scientific focus of the prose. A slow burning plot follows a group of intrepid explorers as they try to uncover the truth of a passing alien spaceship.

You can read our review of Rendevous with Rama here.



Wool by Hugh Howey

Set in a future where all of humanity lives in one underground silo. Wool mixes dystopian with hard science-fiction in an intense novel. The novel twists and turns in ways that constantly subvert the reader’s expectations.

At its heart, Wool is a  novel about humanity under pressure and the importance of dealing with the present without being defined by the past. It’s the newest entry on this list, and in some ways the most refreshing. You can read our review here.



Mission of Gravity, by Hal Clement

One of the very first hard science fiction novels. Mission of Gravity takes place on an inhospitable world, which has surface gravity that varies between 700 g and 3 g. Despite the exotic location one of the key themes of the novel is that the physical rules of the universe are constant.




The Moon is a Harsh Mistress by Robert A. Heinlein

Moo is a harsh mistress book coverThe Moon is a Harsh Mistress was released in the mid-60s and still has the power to make you think. This classic science fiction work explores libertarian ideas through a plot involving a human colony on the moon revolting against their masters on Earth. The Moon is a Harsh Mistress was highly commended for its believable portrayal of a lunar colony on its release. It’s one we’d recommend to lovers of classic science fiction or those looking for a book to challenge their thinking.

Alternate history science fiction

Novels that take place in a different timeline than the one we live in.

The Man in the High Castle by Philip K Dick

Before it was a middling Amazon Original ‘The Man in the High Castle‘ was a mind-bending novel from the late Philip K Dick. Like much of Dick’s work, the novel forces you to consider the nature of reality and your relationship with it. We delved into the nature of fragile reality as depicted in The Man in the High Castle in this article.




Watchmen (graphic novel) by Alan Moore

Set in an even bleaker version of the cold war than the real one, with real super (and not so super) heroes, Watchmen is a cult classic for a reason.

Not only does it completely subvert the concept of the vigilante superhero, it’s also a biting satire that has become only more relevant in the passing years.



Alien invasion science fiction

Stories that take imagine what it would be like if we were attacked by creatures from out of space.

War of the Worlds by HG Wells

The Granddaddy of alien invasion literature. If it seems a little cliche to the modern reader, that’s just because it’s inspired so many imitators. HG Wells still casts a long shadow over the science fiction genre. After reading this you will understand why.



Day of the Triffids by John Wyndham

The Day of the Triffids is often considered a ‘cosy catastrophe’ where people of Britain fret about the end of the world while sitting around and drinking tea. But John Wyndham’s novel is actually much darker than that. If you can get past the inherent English-ness of the writing, in many ways it can be seen as a precursor to later zombie movies.  You can more about how the Day of the Triffids is still a relevant, and dark, novel here.



Childhood’s End by Arthur C Clarke

A novel in which the aliens come in peace, but at what cost? Considered by some to be Clarke’s greatest work, and that’s some claim when you consider he wrote Rendevous with Rama, Childhood’s End is a book that will stay with you long after you have put it down.




Military science fiction

Sci-fi that deals with the military and war.

The Forever War by Joe Haldeman

The defining book of the military science fiction genre. The Forever War takes the author’s experiences of Vietnam and examines them through the prism of an interstellar war. Like many great anti-war works, it is more about the bits in between the battles than the battles themselves. While some of the attitudes in the novel have dated badly, The Forever War is still rightly considered a classic science fiction novel. You can read our full review and analysis of The Forever War here.

The hard science fiction element to the story is the focus on time dilatation. The human theme of the novel is the effect of war on the soldiers who are trained to fight.


Leviathan Wakes by James SA Corey

Leviathan Wakes James S Carey book coverThe Leviathan Wakes is a military fiction intertwined with a noir detective tale and a political drama. Because of this, the novel is a genuine page-turner as well as being a cool work of science fiction. The plot is intricate and clever and the characters compelling. This multilayered novel has now been made into an excellent TV show that we’d recommend to anyone.



Old Man’s War by John Scalzi

A military science fiction novel with a twist. The super tough space army in this book is made up of geriatrics. Geriatrics who have been given new super-advanced bodies, but geriatrics none-the-less. This dad’s army is then sent out to fight some of the more vicious aliens in science fiction. Although the novel is clearly inspired by The Forever War and Starship Troopers, it is more than a simple homage to these two classic science fiction novels.
