About the book
From the Hugo Award–winning author, the classic millennia-spanning epic in one volume: "A wholly new concept of the far future." —The New York Times
Originally published in four volumes, Cities in Flight brings together the famed "Okie novels" of science fiction master James Blish. Named after the migrant workers of America's Dust Bowl, these novels convey Blish's "history of the future," a brilliant and bleak look at a world where cities roam the Galaxy looking for work and a sustainable way of life.
In the first novel, They Shall Have Stars, humankind has thoroughly explored the solar system, yet the dream of going even farther seems to have died in all but one man. His battle to realize his dream results in two momentous discoveries: anti-gravity and the secret of immortality. In A Life for the Stars, it is centuries later and antigravity generations have enabled whole cities to lift off the surface of the earth to become galactic wanderers. In Earthman, Come Home, the nomadic cities revert to barbarism and marauding rogue cities begin to pose a threat to all civilized worlds. In the final novel, The Triumph of Time, history repeats itself as the cities once again journey back into space, making a terrifying discovery which could destroy the entire universe. A serious and haunting vision of our world and its limits, Cities in Flight marks a milestone in science fiction.
"Compelling . . . If you haven't read this yet, I envy you. Blish's cities will fly through your dreams." —Stephen Baxter
"In a century that brimmed with human short-sightedness, James Blish was one of the very first genuine visionaries of a new millennium." —David Brin

About the book
Henry Morgan went to a baseball game hoping to catch a pop fly - not an untimely death from a flying lawnmower to the head.

In the year 2117, humanity is confronted by a metastasizing alien threat that's already established itself in the asteroid belt.
It's Henry the starship's job to sail out to it, investigate it, and end it.
Or to die trying.

About the book
From New York Times bestselling author and astronaut Chris Hadfield comes this exceptional thriller into the dark heart of the Cold War and the space race—soon to be a major TV series from Altitude and Sylvester Stallone’s Balboa Productions.
"An exciting journey" —Andy Weir, author of The Martian and Project Hail Mary
1973: a final, top-secret mission to the Moon. Three astronauts in a tiny spaceship, a quarter million miles from home. A quarter million miles from help.
NASA is about to launch Apollo 18. While the mission has been billed as a scientific one, flight controller Kazimieras "Kaz" Zemeckis knows there is a darker objective. Intelligence has discovered a secret Soviet space station spying on America, and Apollo 18 may be the only chance to stop it. But even as Kaz races to keep the NASA crew one step ahead of their Russian rivals, a deadly accident reveals that not everyone involved is quite who they were thought to be. With political stakes stretched to the breaking point, the White House and the Kremlin can only watch as their astronauts collide on the lunar surface, far beyond the reach of law or rescue.
Full of the fascinating technical detail that fans of The Martian loved, and reminiscent of the thrilling claustrophobia, twists, and tension of The Hunt for Red October, The Apollo Murders is a high-stakes thriller unlike any other. Chris Hadfield captures the fierce G-forces of launch, the frozen loneliness of space, and the fear of holding on to the outside of a spacecraft orbiting the Earth at 17,000 miles per hour as only someone who has experienced all of these things in real life can.
"Packed with cosmic action ... Featuring undercover spies, scheming Russians and psychopathic murderers, sometimes all at once, it teems with authoritative details." —The New York Times
“Nail-biting ... I couldn’t put it down.” —James Cameron, writer and director of Avatar and Titanic
“Not to be missed.” —Frederick Forsyth, author of The Day of the Jackal
“An explosive thriller by a writer who has actually been to space ... Strap in for the ride!” —Gregg Hurwitz, author of Orphan X

About the book
A compulsively readable queer sci-fi novel about a marriage of convenience between a Mars politician and an Earth refugee.
Named a Best Book of 2024 by The Washington Post * Amazon * Book Riot * LitHub * Paste Magazine * HuffPost
In the wake of an environmental catastrophe, January, once a principal in London's Royal Ballet, has become a refugee in Tharsis, the terraformed colony on Mars. There, January's life is dictated by his status as an Earthstronger-a person whose body is not adjusted to lower gravity and so poses a danger to those born on, or naturalized to, Mars. January's job choices, housing, and even transportation are dictated by this second-class status, and now a xenophobic politician named Aubrey Gale is running on a platform that would make it all worse: Gale wants all Earthstrongers to naturalize, a process that is always disabling and sometimes deadly.
When Gale chooses January for an on-the-spot press junket interview that goes horribly awry, January's life is thrown into chaos, but Gale's political fortunes are damaged, too. Gale proposes a solution to both their problems: a five year made-for-the-press marriage that would secure January's future without naturalization and ensure Gale's political success. But when January accepts the offer, he discovers that Gale is not at all like they appear in the press. They're kind, compassionate, and much more difficult to hate than January would prefer. As their romantic relationship develops, the political situation worsens, and January discovers Gale has an enemy, someone willing to destroy all of Tharsis to make them pay-and January may be the only person standing in the way.
Un-put-downably immersive and utterly timely, Natasha Pulley's new novel is a gripping story about privilege, strength, and life across class divisions, perfect for readers of Sarah Gailey and Tamsyn Muir.

Our take
Ethan Cross expects an ordinary night shift until an impossible machine appears behind his plant. After he touches it, a countdown begins and his life is pulled toward the stars, with a 4.4-star rating from more than 4,500 Amazon reviewers. Best for readers who like first-contact science fiction, mysterious alien technology, and ordinary people thrust into interstellar danger.
Choose your retailer
About the book
Ethan Cross expected second shift at Meridian Industrial to end the way it always did—oil-stained hands, clock out, go home.
Then something impossible shows up behind the plant. It isn’t on any schedule. It isn’t on any radar. And it definitely isn’t human.
Ethan makes one mistake, he gets close.
That’s when his ordinary life ends. Whatever is sitting in the dark isn’t debris or a prank—it’s a machine built for a purpose, and it didn’t arrive by accident. Ethan doesn’t know what it wants, or who it belongs to, but he knows this much: the moment he touched it, a countdown started.
Some doors open to freedom. Some open to trouble.
This one opens to the stars.

The Fourth Consort

Our take
A human representative to Unity finds himself marooned on an alien planet, navigating survival between dangerous natives, a nightmarish stickman, and his potentially lethal companion Neera, with a 4.4-star rating from more than 800 Amazon reviewers. The Fourth Consort is a sharp fit for readers drawn to first contact sci-fi, dark comedy, alien politics, and survival under bizarre pressure.
Choose your retailer
About the book
A new standalone sci-fi novel from Edward Ashton, author of Mickey7 (the inspiration for the major motion picture Mickey 17).
Dalton Greaves is a hero. He’s one of humankind’s first representatives to Unity, a pan-species confederation working to bring all sentient life into a single benevolent brotherhood.
That’s what they told him, anyway. The only actual members of Unity that he’s ever met are Boreau, a giant snail who seems more interested in plunder than spreading love and harmony, and Boreau’s human sidekick, Neera, who Dalton strongly suspects roped him into this gig so that she wouldn’t become the next one of Boreau’s crew to get eaten by locals while prospecting.
Funny thing, though—turns out there actually is a benevolent confederation out there, working for the good of all life. They call themselves the Assembly, and they really don’t like Unity. More to the point, they really, really don’t like Unity’s new human minions.
When an encounter between Boreau’s scout ship and an Assembly cruiser over a newly discovered world ends badly for both parties, Dalton finds himself marooned, caught between a stickman, one of the Assembly’s nightmarish shock troops, the planet’s natives, who aren’t winning any congeniality prizes themselves, and Neera, who might actually be the most dangerous of the three. To survive, he’ll need to navigate palace intrigue, alien morality, and a proposal that he literally cannot refuse, all while making sure Neera doesn’t come to the conclusion that he’s worth more to her dead than alive.
Part first contact story, part dark comedy, and part bizarre love triangle, The Fourth Consort asks an important question: how far would you go to survive? And more importantly, how many drinks would you need to go there?

2010: Odyssey Two
Sci-Fi · First Contact · Hard Sci-Fi · Space Exploration
Our take
Nine years after disaster, humanity returns to Jupiter seeking answers from a silence that never stopped watching. In 2010: Odyssey Two, Heywood Floyd joins a Soviet-American mission to uncover what happened to Discovery One, HAL, and David Bowman. Arthur C. Clarke turns first contact into a cerebral journey through alien intelligence, human ambition, and the terrifying scale of cosmic evolution.
Choose your retailer
About the book
The celebrated author continues his Space Odyssey with this Hugo Award winner: "A daring romp through the solar system and a worthy successor to 2001" (Carl Sagan).
In 1968, Arthur C. Clarke's bestselling 2001: A Space Odyssey captivated the world and was adapted into the classic film by Stanley Kubrick. Fourteen years later, fans and critics were thrilled by the release of 2010: Odyssey Two.
Nine years after the ill-fated Discovery One mission to Jupiter, a joint Soviet-American crew travels to the planet to investigate the mysterious monolith orbiting the planet, the cause of the earlier mission's failure—and what became of astronaut David Bowman. The crew includes project expert Heywood Floyd, and Dr. Chandra, the creator of HAL 9000.
What they discover is an unsettling alien conspiracy tampering with the evolution of life on Jupiter's moons as well as that of humanity itself. Meanwhile, the being that was once Dave Bowman—the only human to unlock the mystery of the monolith—streaks toward Earth on a vital mission of its own . . .
"Clarke deftly blends discovery, philosophy, and a newly acquired sense of play." —Time
"2010 is easily Clarke's best book in over a decade." —The San Diego Union-Tribune

Exile has made the Fant essential, but the secrets they guard may be more dangerous than the galaxy knows.
Barsk
Dystopian · Sci-Fi · Space Exploration · Space Opera
Our take
Exile has made the Fant essential, but the secrets they guard may be more dangerous than the galaxy knows. In Barsk: The Elephants’ Graveyard, sentient elephants on a rain-soaked world hold the key to speaking with the dead, while Jorl’s search for truth and Pizlo’s strange visions expose buried power. This is speculative science fiction with mystery, grief, and expansive post-human worldbuilding.
Choose your retailer
About the book
In a post-human future, sentient elephants who speak with the dead uncover a devastating secret in this "weird, wise, and worldly…triumph" (Hugo Award-winning author Robert J. Sawyer).
In a distant future, humans are extinct, but their successors—animals uplifted into walking, talking, sentient beings—thrive across the galaxy. The Fant are anthropomorphic elephants, exiled to the rainy ghetto world of Barsk. Though they are ostracized by other races, they develop essential medicines upon which all species depend. The most coveted is the drug Koph, which allows users to interact with the recently deceased and learn their secrets.
Now a shadowy group is forcing the Fant to surrender their knowledge and claim Koph for themselves. A Fant named Jorl is compelled to question his deceased best friend, who years ago mysteriously committed suicide. But in so doing, Jorl unearths a secret the powers that be would prefer to keep buried forever.
Meanwhile, his dead friend's son, a physically challenged young Fant named Pizlo, is driven by disturbing visions to take his first unsteady steps toward an uncertain future.
