Book cover of World War Z: An Oral History of the Zombie War

Chris Kempshall Author Of Star Wars: The Rise and Fall of the Galactic Empire

From my list on fictional non-fiction.

Why am I passionate about this?

I’m a historian, and while I have a great deal of experience producing straight ‘nonfiction’ work, the idea of reading something ‘non-fictional;’ within a fictional world has always excited me because it allows many opportunities to talk about us while framing it as them. They also play into what I call the ‘Rutger Hauer Effect,’ where his character in Blade Runner mentions the wonderous things he’s seen in passing. I want to see those things too! Fictional nonfiction books provide a fantastic opportunity to tease the readers with things that their author knows and has seen but exist just beyond the reach of our own imaginations.

This is an absolute classic of the genre. Brooks draws in various ‘accounts’ of a recent zombie outbreak and structures them as if the broad details are common knowledge to his in-universe audience.

This approach means the real-world reader is always discovering new details and nuggets of information in a way that really whets the appetite while increasing the sense of horror at the way events unfolded in a world that isn’t quite our own.

What is this book about?

It began with rumours from China about another pandemic. Then the cases started to multiply and what had looked like the stirrings of a criminal underclass, even the beginning of a revolution, soon revealed itself to be much, much worse.

Faced with a future of mindless man-eating horror, humanity was forced to accept the logic of world government and face events that tested our sanity and our sense of reality. Based on extensive interviews with survivors and key players in the ten-year fight against the horde, World War Z brings the finest traditions of journalism to bear on what is…


Book cover of The Grapes of Wrath

Nick Brown Author Of The Siege: Agent of Rome 1

From my list on books that take you to another world.

Why am I passionate about this?

Before I was a writer, I was a reader.  My mother was a primary school teacher, so I was encouraged to read from my earliest years. I wanted to be not only entertained but transported to another place, time, or world. When I finally decided to write my first novel, I settled on historical fiction, but I have since written both science fiction and fantasy. I always endeavour to emulate my literary heroes and create engaging characters, compelling plots, and an interesting, unusual, convincing world.

Though set less than a century ago, the world of Steinbeck’s novel is so very different from our own. This masterpiece follows the Joad family as they head west to California, escaping the hardship and poverty of the Oklahoma Dust Bowl.

Depression-era America is described with such detail and emotion that the reader feels almost like a companion of the Joads, each of whom are rendered with precision and depth. In other hands, this might have been a grim, gloomy tale, but Steinback evokes themes of loyalty, kindness, and pride with peerless power and skill.

17 authors picked The Grapes of Wrath as one of their favorite books, and they share why you should read it.

What is this book about?

'I've done my damndest to rip a reader's nerves to rags, I don't want him satisfied.'

Shocking and controversial when it was first published, The Grapes of Wrath is Steinbeck's Pultizer Prize-winning epic of the Joad family, forced to travel west from Dust Bowl era Oklahoma in search of the promised land of California. Their story is one of false hopes, thwarted desires and powerlessness, yet out of their struggle Steinbeck created a drama that is both intensely human and majestic in its scale and moral vision.


Book cover of Leviathan Wakes

Matt Shindell Author Of For the Love of Mars: A Human History of the Red Planet

From my list on human connection to space.

Why am I passionate about this?

One of the reasons I love my job as a Space History Curator at the Smithsonian’s National Air and Space Museum is that I am fascinated to learn how people think about space, the cosmos, and their human connection with the universe. I am always eager to get beyond questions of what we know and how we know it and ask: Why do we ask the questions we ask in the first place? The books I’ve listed here all explore our relationship with space and how we engage personally or collectively with space exploration.

Matt's book list on human connection to space

Matt Shindell Why did Matt love this book?

This science fiction novel, written by Daniel Abraham and Ty Franck under the pen name James S. A. Corey, was the beginning of the Expanse series (now totaling 9 novels and additional stories). It is one of the best space science fiction novels of the 21st century and became the basis for one of my favorite TV/streaming series, The Expanse.

The books dive deep into the political, social, and cultural complexities of sending humans to live on the Moon, Mars, and the asteroid belt, and it’s a nuanced reflection of our current ideas and ambitions when it comes to spaceflight. I am particularly drawn to the depiction of humans who, after multiple generations off Earth, consider their primary identity to be Martian.

Humanity has colonized the planets - interstellar travel is still beyond our reach, but the solar system has become a dense network of colonies. But there are tensions - the mineral-rich outer planets resent their dependence on Earth and Mars and the political and military clout they wield over the Belt and beyond. Now, when Captain Jim Holden's ice miner stumbles across a derelict, abandoned ship, he uncovers a secret that threatens to throw the entire system into war. Attacked by a stealth ship belonging to the Mars fleet, Holden must find a way to uncover the motives behind the…


Book cover of The Forever War

Jools Cantor Author Of The Trellis

From my list on real-life time machines through sci fi.

Why am I passionate about this?

Science fiction lets us readers escape into space or travel through time, but I believe it is most effective when grounded in our primal anxieties. Classics like Nineteen Eighty-Four and The Handmaid’s Tale resonate because the dark futures they describe drive us to prevent their prophecy. These stories give us a window into the world that birthed them by crystalizing the authors' fears into a work of fiction. When I read each book on this list, they transported me to the time they were written. En route, they showed how much our world has changed and how much we humans haven’t.

Jools' book list on real-life time machines through sci fi

Jools Cantor Why did Jools love this book?

This book is one of the best military science fiction stories and an excellent anti-war novel. It mixes compelling action and smart science with real frustrations, emotions, and horror as the futility of war is exposed. Haldeman based the story on his own experiences in Vietnam, and the story revolves around a similar soldier who struggles to make sense of the war he is fighting and the home he no longer recognizes.

While it’s a great window into the American psyche in 1975, it is best read immediately after Robert Heinlein's Starship Troopers, which reflects America's rah-rah militarism in 1959. This way, you can read a bunch of action-packed sex and violence while also telling your high-brow friends that you’re “exploring the subtextual divergence in American attitudes toward interventionism in literature through the latter half of the twentieth century” or something like that.

The monumental Hugo and Nebula award winning SF classic-- Featuring a new introduction by John Scalzi

The Earth's leaders have drawn a line in the interstellar sand--despite the fact that the fierce alien enemy they would oppose is inscrutable, unconquerable, and very far away. A reluctant conscript drafted into an elite Military unit, Private William Mandella has been propelled through space and time to fight in the distant thousand-year conflict; to perform his duties and do whatever it takes to survive the ordeal and return home. But "home" may be even more terrifying than battle, because, thanks to the time…


Book cover of Project Hail Mary

Phil Bailey Author Of Kelvoo's Testimonial: Surviving the aftermath of human first contact

From my list on first contact science fiction novels.

Why am I passionate about this?

Of all the intelligent species (both real and fictional), humans fascinate me the most. For me, it’s the creativity and diversity of humans that both divide and unite us. Our eternal struggle to understand one another and overcome our differences fascinates me. I love first-contact science fiction that lets us view the values and behavior of our own species through the lens of true outsiders. I find great value in these parables when they increase self-awareness of our identities and our effect on others.

Phil's book list on first contact science fiction novels

Phil Bailey Why did Phil love this book?

Andy Weir was one of my favorite sci-fi authors the moment I finished reading The Martian, so I had to read his first contact novel as soon as it was published. As a hard science fiction fan, I appreciated that the author “did the math” when describing problems that arose and the solutions that were implemented during a do-or-die mission to save the Earth.

Having said that, math was one of my least favorite subjects in school, but the author made the technical details easy to understand and very interesting. I also appreciated that the extraterrestrial was written to be alien in so many aspects instead of relying on an often-used human-like alien trope.

Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish.

Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.

All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through…


Book cover of Starship Troopers

Thomas P. Hopp Author Of Dinosaur Wars: Earthfall

From my list on sci-fi about dinosaurs and monstrous creatures.

Why am I passionate about this?

I’ve been a fan of dinosaurs and other mega-monsters ever since I watched the original Godzilla movie as a kid. It scared me half out of my wits! There’s something about big, scaly, dangerous beasts that makes for a great adventure story. Add fascinating human characters and you’ve got my full attention. I started writing my Dinosaur Wars books precisely to fill the void where there are far too few stories of this type in current literature. Challenges between human heroes and giant beasts have been part of literature from the start, featuring dragons, titans, and ocean leviathans. I see my writings as efforts to continue that tradition.

Thomas P. Hopp Why did Thomas love this book?

This book by Robert Heinlein is an action-packed space adventure featuring creepy insect foes in an interstellar battle with Earth. It follows Trooper Johnny Rico in an epic war story set on distant worlds.

The book features a number of combat engagements with gigantic insect-like “Arachnids” and other bug-like creatures. Meanwhile, several love affairs arise and crumble in the face of Rico’s commitment to the warrior life. While the book has been criticized as preachy and moralizing, these are foibles that I tolerated well, knowing that another action sequence would not be long in coming.

Book cover of Hyperion

Sergio Almécija Author Of Humans: Perspectives on Our Evolution from World Experts

From my list on the big picture of human nature and evolution.

Why am I passionate about this?

I have researched human origins professionally for almost decades by studying the trail of fossils that have survived millions of years. But, before then, and since I can remember, I’ve been a lover of adventure and science fiction stories in all formats: action movies (Indiana Jones, Back to the Future), TV shows (The X Files), novels (Jack London!), or anime and manga (Ghost in the Shell, Akira, Alita). So, I guess my mind constantly travels from the past to the future. I think this list will also work as a time machine for others.

Sergio's book list on the big picture of human nature and evolution

Sergio Almécija Why did Sergio love this book?

This book is a classic now and will still be one hundred years from now. It’s the only truly fiction book on this list, but it contains some of the deepest truths about human nature, the meaning of time, memory, and identity.

Different narrators tell their tragic stories, which converge in a beautifully wrapped-up end set in a dystopian future with an ongoing war among different species descent from modern Homo sapiens. What is not to love about it?

Bryan Wilson Author Of The Forsaken Planet

From my list on books that inspired me to write my book.

Why am I passionate about this?

I have had a love of sci-fi and fantasy since I was twelve, and I have been an avid reader since then. I have always had an obsession with all things space and the mysteries that reside out there, and it was my dream to create a story that intermixed that with the fantasy worlds I grew up adoring. Since I released my debut book, I have broken into the indie social scene across multiple platforms. I am part of a sixteen-person author group where we share our passion and ideas for one another’s writing, and I have been on numerous BookTube channels and podcasts discussing the craft.

Bryan's book list on books that inspired me to write my book

Bryan Wilson Why did Bryan love this book?

I recommend this book because it is my favorite modern sci-fi series. What gripped me with this was the overall premise of the story.

This story starts with the curtain being dropped for the book’s MC, and he realizes his life is not what it seems and his people are nothing more than slaves for a higher order. He sets out to change that. It is an amazing story that took the battle-school trope that I loved in Ender’s Game to a whole new level. I instituted the trope into my book and feel it has a good balance between the YA version of Ender’s Game and the very mature version of Red Rising.

This is my first foray into actual science fantasy, and it definitely influenced my work.

Book cover of At the Mountains of Madness

Elana Gomel Author Of Nine Levels

From my list on mountain climbing for non-climbers.

Why am I passionate about this?

I always want to be where I am not. This was why I read sci-fi and fantasy as a child. This was why I left the country of my birth and became a professional nomad. This is why I am spellbound by mountains I will never climb and oceans I will never dive into. Imagination can take you everywhere. It took me to the academy, where speculative literature became my scholarly field, and to the publishing world, where I am now getting ready for the launch of my eighth novel. When you are at home nowhere, you are at home everywhere–including on the summits of impossible mountains.

Elana's book list on mountain climbing for non-climbers

Elana Gomel Why did Elana love this book?

I am not frightened by Cthulhu, the tentacled monsters waiting in the depths of outer space or the ocean. I am mesmerized by them. Lovecraft, often labeled a horror writer, is one of the greatest literary fantasists. His imagination is boundless, and he is as adept at describing strange new environments as he is at evoking a sense of cosmic dread.

This classic novel combines Lovecraft’s signature monsters with an incredible dreamlike atmosphere that grips you and does not let you go. When you stand at the summit of the Mountains of Madness and glimpse what lies on the other side, you are torn between fear and fascination. For me, at least, fascination always wins.

At the Mountains of Madness is a science fiction-horror novella by American author H. P. Lovecraft.

An expedition to Antarctica goes horribly wrong as a group of explorers stumbles upon some mysterious ancient ruins, with devastating consequences. At the Mountains of Madness ranks among Lovecraft's most terrifying novellas, and is a firm favourite among fans of classic horror.


Book cover of Ender's Game

Christopher Farrar Author Of By the Waters of Babylon

From my list on fantasy and scifi about ethical and moral growth.

Why am I passionate about this?

My dad raised me on science fiction and fantasy. At first, it was enough for me to be entertained by stories of spaceflight, of rescuing maidens in distress, and of fighting bug-eyed monsters. But over the years, as I read more, I realized that I wanted stories with a moral or ethical center, stories where murder, mayhem, and war were to be avoided if possible, and where, if they couldn’t be avoided, the protagonists struggled deeply with the moral dimensions of the actions forced upon them. I wanted to see characters growing into their ethical consciousness.

Christopher's book list on fantasy and scifi about ethical and moral growth

Christopher Farrar Why did Christopher love this book?

I love this book because although it seems at a casual glance to be written in the mold of 50s and 60s science fiction, with earthmen fighting bug-eyed aliens, it’s, in fact, a profound exploration of the morality of war, of chances, lost and motives misunderstood and of the ruthless use of children as combatants.

The training regimen of the children is gripping, as is the climactic space battle, but it’s the ending of the novel that gives the story its deep spiritual resonance.
