The Hitchhiker’s Guide to the Galaxy

Douglas Adams

The Hitchhikers Guide To The Galaxy Series
  • Save

Nominated as one of America’s best-loved novels by PBS’s The Great American Read

It’s an ordinary Thursday morning for Arthur Dent . . . until his house gets demolished. The Earth follows shortly after to make way for a new hyperspace express route, and Arthur’s best friend has just announced that he’s an alien.

After that, things get much, much worse.

With just a towel, a small yellow fish, and a book, Arthur has to navigate through a very hostile universe in the company of a gang of unreliable aliens. Luckily the fish is quite good at languages. And the book is The Hitchhiker’s Guide to the Galaxy . . . which helpfully has the words DON’T PANIC inscribed in large, friendly letters on its cover.

Douglas Adams’s mega-selling pop-culture classic sends logic into orbit, plays havoc with both time and physics, offers up pithy commentary on such things as ballpoint pens, potted plants, and digital watches . . . and, most important, reveals the ultimate answer to life, the universe, and everything.

Now, if you could only figure out the question. . . .

John Dies at the End – David Wong

  • Save

My name is David Wong. My best friend is John. Those names are fake. You might want to change yours. You may not want to know about the things you’ll read on these pages, about the sauce, about Korrock, about the invasion, and the future. But it’s too late. You touched the book. You’re in the game.

The only defence is knowledge. You need to read this book, to the end. Even the part about the bratwurst. Why? You’ll just have to trust me. Unfortunately for us, if you make the right choice, we’ll have a much harder time explaining how to fight off the otherwordly invasion currently threatening to enslave humanity.

I’m sorry to have involved you in this, I really am. But as you read about these terrible events and the very dark epoch the world is about to enter as a result, it is crucial you keep one thing in mind: NONE OF THIS IS MY FAULT…

To Say Nothing of the Dog – Connie Willis

Funny Sci Fi Books

Ned Henry is badly in need of a rest. He’s been shuttling between the twenty-first century and the 1940s in search of a Victorian atrocity called the bishop’s bird stump as part of a project to restore the famed Coventry Cathedral, destroyed in a Nazi air raid more than a hundred years earlier.

But then Verity Kindle, a fellow time traveler, inadvertently brings back something from the past. Now Ned must jump to the Victorian era to help Verity put things right—not only to save the project but also to prevent altering history itself.

Slaughterhouse-Five – Kurt Vonnegut

Funny Sci Fi Books
  • Save

Slaughterhouse-Five, an American classic, is one of the world’s great antiwar books. Centering on the infamous World War II firebombing of Dresden, the novel is the result of what Kurt Vonnegut described as a twenty-three-year struggle to write a book about what he had witnessed as an American prisoner of war. It combines historical fiction, science fiction, autobiography, and satire in an account of the life of Billy Pilgrim, a barber’s son turned draftee turned optometrist turned alien abductee. As Vonnegut had, Billy experiences the destruction of Dresden as a POW. Unlike Vonnegut, he experiences time travel, or coming “unstuck in time.”

Gun, with Occasional Music – Jonathon Lethem

Funny Sci Fi Books
  • Save

A hard-boiled detective tale full of talking animals and murder, from the award-winning author of Motherless Brooklyn and The Arrest.Gumshoe Conrad Metcalf has problems—there’s a rabbit in his waiting room and a trigger-happy kangaroo on his tail. Near-future Oakland is a brave new world where evolved animals are members of society, the police monitor citizens by their karma levels, and mind-numbing drugs such as Forgettol and Acceptol are all the rage.

Mixing elements of sci-fi, noir, and mystery, this clever first novel from a beloved author is a wry, funny, and satiric look at all that the future may hold.

Metcalf has been shadowing Celeste, the wife of an affluent doctor. Perhaps he’s falling a little in love with her at the same time. When the doctor turns up dead, our amiable investigator finds himself caught in a crossfire between the boys from the Inquisitor’s Office and gangsters who operate out of the back room of a bar called the Fickle Muse.

Year Zero – Rob Reid

  • Save


Low-level entertainment lawyer Nick Carter thinks it’s a prank, not an alien encounter, when a redheaded mullah and a curvaceous nun show up at his office. But Frampton and Carly are highly advanced (if bumbling) extraterrestrials. The entire cosmos, they tell him, has been hopelessly hooked on American pop songs ever since “Year Zero” (1977 to us), resulting in the biggest copyright violation since the Big Bang and bankrupting the whole universe. Nick has just been tapped to clean up this mess before things get ugly. Thankfully, this unlikely galaxy-hopping hero does know a thing or two about copyright law. Now, with Carly and Frampton as his guides, Nick has forty-eight hours to save humanity—while hoping to wow the hot girl who lives down the hall from him.

The Eyre Affair – Jasper Fforde

Funny Sci Fi Books
  • Save

Fans of Douglas Adams and P. G. Wodehouse will love visiting Jasper Fforde’s Great Britain, circa 1985, when time travel is routine, cloning is a reality (dodos are the resurrected pet of choice), and literature is taken very, very seriously: it’s a bibliophile’s dream. England is a virtual police state where an aunt can get lost (literally) in a Wordsworth poem and forging Byronic verse is a punishable offense. All this is business as usual for Thursday Next, renowned Special Operative in literary detection. But when someone begins kidnapping characters from works of literature and plucks Jane Eyre from the pages of Brontë’s novel, Thursday is faced with the challenge of her career. Fforde’s ingenious fantasy—enhanced by a Web site that re-creates the world of the novel—unites intrigue with English literature in a delightfully witty mix.

The Automatic Detective – A. Lee Martinez

Funny Sci Fi Books

Even in Empire City, a town where weird science is the hope for tomorrow, it’s hard for a robot to make his way. It’s even harder for a robot named Mack Megaton, a hulking machine designed to bring mankind to its knees. But Mack’s not interested in world domination. He’s just a bot trying to get by, trying to demonstrate that he isn’t just an automated smashing machine, and to earn his citizenship in the process. It should be as easy as crushing a tank for Mack, but some bots just can’t catch a break.

When Mack’s neighbors are kidnapped, Mack sets off on a journey through the dark alleys and gleaming skyscrapers of Empire City. Along the way, he runs afoul of a talking gorilla, a brainy dame, a mutant lowlife, a little green mob boss, and the secret conspiracy at the heart of Empire’s founders—not to mention more trouble than he bargained for. What started out as one missing family becomes a battle for the future of Empire and every citizen that calls her home.

Space Opera – Catherynne M. Valente

Funny Sci Fi Books
  • Save

A century ago, the Sentience Wars tore the galaxy apart and nearly ended the entire concept of intelligent space-faring life. In the aftermath, a curious tradition was invented—something to cheer up everyone who was left and bring the shattered worlds together in the spirit of peace, unity, and understanding.

Once every cycle, the great galactic civilizations gather for the Metagalactic Grand Prix—part gladiatorial contest, part beauty pageant, part concert extravaganza, and part continuation of the wars of the past. Species far and wide compete in feats of song, dance and/or whatever facsimile of these can be performed by various creatures who may or may not possess, in the traditional sense, feet, mouths, larynxes, or faces. And if a new species should wish to be counted among the high and the mighty, if a new planet has produced some savage group of animals, machines, or algae that claim to be, against all odds, sentient? Well, then they will have to compete. And if they fail? Sudden extermination for their entire species.

Becky Chambers

Follow a motley crew on an exciting journey through space—and one adventurous young explorer who discovers the meaning of family in the far reaches of the universe—in this light-hearted debut space opera from a rising sci-fi star.

Rosemary Harper doesn’t expect much when she joins the crew of the aging Wayfarer. While the patched-up ship has seen better days, it offers her a bed, a chance to explore the far-off corners of the galaxy, and most importantly, some distance from her past. An introspective young woman who learned early to keep to herself, she’s never met anyone remotely like the ship’s diverse crew, including Sissix, the exotic reptilian pilot, chatty engineers Kizzy and Jenks who keep the ship running, and Ashby, their noble captain.

Life aboard the Wayfarer is chaotic and crazy—exactly what Rosemary wants. It’s also about to get extremely dangerous when the crew is offered the job of a lifetime. Tunneling wormholes through space to a distant planet is definitely lucrative and will keep them comfortable for years. But risking her life wasn’t part of the plan. In the far reaches of deep space, the tiny Wayfarer crew will confront a host of unexpected mishaps and thrilling adventures that force them to depend on each other. To survive, Rosemary’s got to learn how to rely on this assortment of oddballs—an experience that teaches her about love and trust, and that having a family isn’t necessarily the worst thing in the universe.

Old Man’s War – John Scalzi

Funny Sci Fi Books
  • Save

John Perry did two things on his 75th birthday. First he visited his wife’s grave. Then he joined the army.

The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce-and aliens willing to fight for them are common. The universe, it turns out, is a hostile place.

So: we fight. To defend Earth (a target for our new enemies, should we let them get close enough) and to stake our own claim to planetary real estate. Far from Earth, the war has gone on for decades: brutal, bloody, unyielding.

Earth itself is a backwater. The bulk of humanity’s resources are in the hands of the Colonial Defense Force, which shields the home planet from too much knowledge of the situation. What’s known to everybody is that when you reach retirement age, you can join the CDF. They don’t want young people; they want people who carry the knowledge and skills of decades of living. You’ll be taken off Earth and never allowed to return. You’ll serve your time at the front. And if you survive, you’ll be given a generous homestead stake of your own, on one of our hard-won colony planets.

The Humans – Matt Haig

When an extra-terrestrial visitor arrives on Earth, his first impressions of the human species are less than positive. Taking the form of Professor Andrew Martin, a prominent mathematician at Cambridge University, the visitor is eager to complete the gruesome task assigned him and hurry home to his own utopian planet, where everyone is omniscient and immortal.

He is disgusted by the way humans look, what they eat, their capacity for murder and war, and is equally baffled by the concepts of love and family. But as time goes on, he starts to realize there may be more to this strange species than he had thought. Disguised as Martin, he drinks wine, reads poetry, develops an ear for rock music, and a taste for peanut butter. Slowly, unexpectedly, he forges bonds with Martin’s family. He begins to see hope and beauty in the humans’ imperfection, and begins to question the very mission that brought him there.

Carry On – Rainbow Rowell

  • Save

Simon Snow is the worst Chosen One who’s ever been chosen.

That’s what his roommate, Baz, says. And Baz might be evil and a vampire and a complete git, but he’s probably right.

Half the time, Simon can’t even make his wand work, and the other half, he starts something on fire. His mentor’s avoiding him, his girlfriend broke up with him, and there’s a magic-eating monster running around, wearing Simon’s face. Baz would be having a field day with all this, if he were here — it’s their last year at the Watford School of Magicks, and Simon’s infuriating nemesis didn’t even bother to show up.

Carry On is a ghost story, a love story and a funny Sci Fi book. It has just as much kissing and talking as you’d expect from a Rainbow Rowell story – but far, far more monsters.

The Rest of Us Just Live Here – Patrick Ness

  • Save

A bold and irreverent YA novel. One of the best YA Funny Sci Fi Books!

What if you aren’t the Chosen One? The one who’s supposed to fight the zombies, or the soul-eating ghosts, or whatever the heck this new thing is, with the blue lights and the death?

What if you’re like Mikey? Who just wants to graduate and go to prom and maybe finally work up the courage to ask Henna out before someone goes and blows up the high school. Again.

Because sometimes there are problems bigger than this week’s end of the world, and sometimes you just have to find the extraordinary in your ordinary life.

Even if your best friend is worshipped by mountain lions.

Gate Crashers – Patrick S. Tomlinson

The only thing as infinite and expansive as the universe is humanity’s unquestionable ability to make bad decisions.

Humankind ventures further into the galaxy than ever before… and immediately causes an intergalactic incident. In their infinite wisdom, the crew of the exploration vessel Magellan, or as she prefers “Maggie,” decides to bring the alienstructure they just found back to Earth. The only problem? The aliens are awfully fond of that structure.

A planet full of highly evolved primates is on a collision course with a far wider, and more hostile, galaxy.

All Systems Red – Martha Wells

  • Save

A murderous android discovers itself in All Systems Red. A tense but funny Sci Fi book by Martha Wells that interrogates the roots of consciousness through Artificial Intelligence.

In a corporate-dominated spacefaring future, planetary missions must be approved and supplied by the Company. Exploratory teams are accompanied by Company-supplied security androids, for their own safety.

But in a society where contracts are awarded to the lowest bidder, safety isn’t a primary concern.

On a distant planet, a team of scientists are conducting surface tests, shadowed by their Company-supplied ‘droid — a self-aware SecUnit. It has hacked its own governor module, and refers to itself (though never out loud) as “Murderbot.” Scornful of humans, all it really wants is to be left alone long enough to figure out who it is.

But when a neighboring mission goes dark, it’s up to the scientists and their Murderbot to get to the truth.

We Are Legion (We Are Bob)

Bobiverse Book # 1 – Dennis Taylor

Bob Johansson has just sold his software company and is looking forward to a life of leisure. There are places to go, books to read, and movies to watch. So it’s a little unfair when he gets himself killed crossing the street.

Bob wakes up a century later to find that he is now the property of the state. He has been uploaded into computer hardware and is slated to be the controlling AI in an interstellar probe looking for habitable planets. The stakes are high: no less than the first claim to entire worlds. If he declines the honor, he’ll be switched off, and they’ll try again with someone else. If he accepts, he becomes a prime target. There are at least three other countries trying to get their own probes launched first, and they play dirty.


Frequently Asked Questions

Why is Sci-Fi so fun to read?

In Sci-Fi anything is possible. With the realism aspect making you feel as though all these amazing adventures are possible, it’s easy to get warped into books. Funny Sci Fi books may be much easier for a beginner reader of Sci Fi to digest than Hard Sci Fi novels.

What is considered Sci Fi?

Usually futuristic, science fiction speculates about alternative ways of life made possible by technological change. Hence this has sometimes been called “speculative fiction.” Like fantasy, and often associated with it, science fiction envisions alternative worlds with believably consistent rules and structures

Is Historical Sci-Fi a thing?

This seems like a contradictory blend of genres. How can the past merge with the future? Well, it’s hard to do – hence why it’s hard to find! We personally recommend The Iron Widow by Xiran Jay Zhao. Set in the future with the societal significance of ancient China, Zhao incorporates history wonderfully in this retelling of the rise of Wu Zetian, the only female emperor in Chinese history.
