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, he realizes that an impossible task now confronts him. Alone on this tiny ship that's been cobbled together by every government and space agency on the planet and hurled into the depths of space, it's up to him to conquer an extinction-level threat to our species.

And thanks to an unexpected ally, he just might have a chance.

Part scientific mystery, part dazzling interstellar journey, Project Hail Mary is a tale of discovery, speculation, and survival to rival The Martian--while taking us to places it never dreamed of going.

Long before the First Order, before the Empire, before the Clone Wars...Jedi lit the way for the galaxy in the High Republic.

It is a golden age. Intrepid hyperspace scouts expand the reach of the Republic to the farthest stars, worlds flourish under the benevolent leadership of the Senate, and peace reigns, enforced by the wisdom and strength of the renowned order of Force users known as the Jedi. With the Jedi at the height of their power, the free citizens of the galaxy are confident in their ability to weather any storm. But even the brightest light can cast a shadow, and some storms defy any preparation.

When a shocking catastrophe in hyperspace tears a ship to pieces, the flurry of shrapnel emerging from the disaster threatens an entire system. No sooner does the call for help go out than the Jedi race to the scene. The scope of the emergence, however, is enough to push even Jedi to their limit. As the sky breaks open and destruction rains down upon the peaceful alliance they helped to build, the Jedi must trust in the Force to see them through a day in which a single mistake could cost billions of lives.

Even as the Jedi battle valiantly against calamity, something truly deadly grows beyond the boundary of the Republic. The hyperspace disaster is far more sinister than the Jedi could ever suspect. A threat hides in the darkness, far from the light of the age, and harbors a secret that could strike fear into even a Jedi's heart.

The new book by Nebula and Hugo Award-winner, Nnedi Okorafor.

"She’s the adopted daughter of the Angel of Death. Beware of her. Mind her. Death guards her like one of its own."

The day Fatima forgot her name, Death paid a visit. From hereon in she would be known as Sankofa­­--a name that meant nothing to anyone but her, the only tie to her family and her past.

Her touch is death, and with a glance a town can fall. And she walks--alone, except for her fox companion--searching for the object that came from the sky and gave itself to her when the meteors fell and when she was yet unchanged; searching for answers.

But is there a greater purpose for Sankofa, now that Death is her constant companion?

While the Iskat Empire has long dominated the system through treaties and political alliances, several planets, including Thea, have begun to chafe under Iskat's rule. When tragedy befalls Imperial Prince Taam, his Thean widower, Jainan, is rushed into an arranged marriage with Taam's cousin, the disreputable Kiem, in a bid to keep the rising hostilities between the two worlds under control.

But when it comes to light that Prince Taam's death may not have been an accident, and that Jainan himself may be a suspect, the unlikely pair must overcome their misgivings and learn to trust one another as they navigate the perils of the Iskat court, try to solve a murder, and prevent an interplanetary war... all while dealing with their growing feelings for each other.

Set in a world where a virus stalks our male population, The End of Men is an electrifying and unforgettable debut from a remarkable new talent that asks: what would our world truly look like without men?

Only men carry the virus. Only women can save us all.

The year is 2025, and a mysterious virus has broken out in Scotland--a lethal illness that seems to affect only men. When Dr. Amanda MacLean reports this phenomenon, she is dismissed as hysterical. By the time her warning is heeded, it is too late. The virus becomes a global pandemic--and a political one. The victims are all men. The world becomes alien--a women's world.

What follows is the immersive account of the women who have been left to deal with the virus's consequences, told through first-person narratives. Dr. MacLean; Catherine, a social historian determined to document the human stories behind the "male plague"; intelligence analyst Dawn, tasked with helping the government forge a new society; and Elizabeth, one of many scientists desperately working to develop a vaccine. Through these women and others, we see the uncountable ways the absence of men has changed society, from the personal--the loss of husbands and sons--to the political--the changes in the workforce, fertility, and the meaning of family.

In The End of Men, Christina Sweeney-Baird turns the unimaginable into the unforgettable.

No, I didn’t kill the dead human. If I had, I wouldn’t dump the body in the station mall.

When Murderbot discovers a dead body on Preservation Station, it knows it is going to have to assist station security to determine who the body is (was), how they were killed (that should be relatively straightforward, at least), and why (because apparently that matters to a lot of people—who knew?)

Yes, the unthinkable is about to happen: Murderbot must voluntarily speak to humans!

Again!

From the best-selling author of Never Let Me Go and The Remains of the Day, a stunning new novel—his first since winning the Nobel Prize in Literature—about the wondrous, mysterious nature of the human heart.

From her place in the store, Klara, an Artificial Friend with outstanding observational qualities, watches carefully the behavior of those who come in to browse, and of those who pass on the street outside. She remains hopeful that a customer will soon choose her, but when the possibility emerges that her circumstances may change forever, Klara is warned not to invest too much in the promises of humans.

In Klara and the Sun, Kazuo Ishiguro looks at our rapidly changing modern world through the eyes of an unforgettable narrator to explore a fundamental question: what does it mean to love?

I’m embarrassed, still, by how long it took me to notice. Everything was right there in the open, right there in front of me, but it still took me so long to see the person I had married.

It took me so long to hate him.

Martine is a genetically cloned replica made from Evelyn Caldwell’s award-winning research. She’s patient and gentle and obedient. She’s everything Evelyn swore she’d never be.

And she’s having an affair with Evelyn’s husband.

Now, the cheating bastard is dead, and both Caldwell wives have a mess to clean up.

Good thing Evelyn Caldwell is used to getting her hands dirty.

Conspiracies abound in this surreal and yet all-too-real technothriller in which a deadly underground alternate reality game might just be altering reality itself, set in the same world as the popular Rabbits podcast.

It's an average work day. You've been wrapped up in a task, and you check the clock when you come up for air—4:44 pm. You go to check your email, and 44 unread messages have built up. With a shock, you realize it is April 4th—4/4. And when you get in your car to drive home, your odometer reads 44,444. Coincidence? Or have you just seen the edge of a rabbit hole?

Rabbits is a mysterious alternate reality game so vast it uses our global reality as its canvas. Since the game first started in 1959, ten iterations have appeared and nine winners have been declared. Their identities are unknown. So is their reward, which is whispered to be NSA or CIA recruitment, vast wealth, immortality, or perhaps even the key to unlocking the secrets of the universe itself. But the deeper you get, the more deadly the game becomes. Players have died in the past—and the body count is rising.

And now the eleventh round is about to begin. Enter K—a Rabbits obsessive who has been trying to find a way into the game for years. That path opens when K is approached by billionaire Alan Scarpio, the alleged winner of the sixth iteration. Scarpio says that something has gone wrong with the game and that K needs to fix it before Eleven starts or the whole world will pay the price.

Five days later, Scarpio is declared missing. Two weeks after that, K blows the deadline and Eleven begins. And suddenly, the fate of the entire universe is at stake.

In A Psalm for the Wild-Built, Hugo Award-winner Becky Chambers's delightful new Monk and Robot series gives us hope for the future.

It's been centuries since the robots of Panga gained self-awareness and laid down their tools; centuries since they wandered, en masse, into the wilderness, never to be seen again; centuries since they faded into myth and urban legend.

One day, the life of a tea monk is upended by the arrival of a robot, there to honor the old promise of checking in. The robot cannot go back until the question of "what do people need?" is answered.

But the answer to that question depends on who you ask, and how.

They're going to need to ask it a lot.

Becky Chambers's new series asks: in a world where people have what they want, does having more matter?

An adventure set in California's San Gabriel Valley, with cursed violins, Faustian bargains, and queer alien courtship over fresh-made donuts.

Shizuka Satomi made a deal with the devil: to escape damnation, she must entice seven other violin prodigies to trade their souls for success. She has already delivered six.

When Katrina Nguyen, a young transgender runaway, catches Shizuka's ear with her wild talent, Shizuka can almost feel the curse lifting. She's found her final candidate.

But in a donut shop off a bustling highway in the San Gabriel Valley, Shizuka meets Lan Tran, retired starship captain, interstellar refugee, and mother of four. Shizuka doesn't have time for crushes or coffee dates, what with her very soul on the line, but Lan's kind smile and eyes like stars might just redefine a soul's worth. And maybe something as small as a warm donut is powerful enough to break a curse as vast as the California coastline.

As the lives of these three women become entangled by chance and fate, a story of magic, identity, curses, and hope begins, and a family worth crossing the universe for is found.

An alien armada lurks on the edges of Teixcalaanli space. No one can communicate with it, no one can destroy it, and Fleet Captain Nine Hibiscus is running out of options.

A breakthrough in human cloning becomes one woman’s waking nightmare in a mind-bending thriller by the Wall Street Journal bestselling author of the Gibson Vaughn series.

In the near future, advances in medicine and quantum computing make human cloning a reality. For the wealthy, cheating death is the ultimate luxury. To anticloning militants, it’s an abomination against nature. For young Constance “Con” D’Arcy, who was gifted her own clone by her late aunt, it’s terrifying.

After a routine monthly upload of her consciousness—stored for that inevitable transition—something goes wrong. When Con wakes up in the clinic, it’s eighteen months later. Her recent memories are missing. Her original, she’s told, is dead. If that’s true, what does that make her?

The secrets of Con’s disorienting new life are buried deep. So are those of how and why she died. To uncover the truth, Con is retracing the last days she can recall, crossing paths with a detective who’s just as curious. On the run, she needs someone she can trust. Because only one thing has become clear: Con is being marked for murder—all over again.

The Divide.

It’s the edge of the universe.

Now it’s collapsing—and taking everyone and everything with it.

The only ones who can stop it are the Sentinels—the recruits, exiles, and court-martialed dregs of the military.

At the Divide, Adequin Rake, commanding the Argus, has no resources, no comms—nothing, except for the soldiers that no one wanted.

They're humanity's only chance.

A science fiction thriller about artificial intelligence, sentience, and labor rights in a near future dominated by the gig economy.

Welga Ramirez, executive bodyguard and ex-special forces, is about to retire early when her client is killed in front of her. It’s 2095 and people don’t usually die from violence. Humanity is entirely dependent on pills that not only help them stay alive, but allow them to compete with artificial intelligence in an increasingly competitive gig economy. Daily doses protect against designer diseases, flow enhances focus, zips and buffs enhance physical strength and speed, and juvers speed the healing process.

All that changes when Welga’s client is killed by The Machinehood, a new and mysterious terrorist group that has simultaneously attacked several major pill funders. The Machinehood operatives seem to be part human, part machine, something the world has never seen. They issue an ultimatum: stop all pill production in one week.

Global panic ensues as pill production slows and many become ill. Thousands destroy their bots in fear of a strong AI takeover. But the US government believes the Machinehood is a cover for an old enemy. One that Welga is uniquely qualified to fight.

Welga, determined to take down the Machinehood, is pulled back into intelligence work by the government that betrayed her. But who are the Machinehood and what do they really want?

A thought-provoking novel that asks: if we won’t see machines as human, will we instead see humans as machines?

A visionary technothriller about climate change.

Neal Stephenson’s sweeping, prescient new novel transports readers to a near-future world where the greenhouse effect has inexorably resulted in a whirling-dervish troposphere of superstorms, rising sea levels, global flooding, merciless heat waves, and virulent, deadly pandemics.

One man has a Big Idea for reversing global warming, a master plan perhaps best described as “elemental.” But will it work? And just as important, what are the consequences for the planet and all of humanity should it be applied?

Ranging from the Texas heartland to the Dutch royal palace in the Hague, from the snow-capped peaks of the Himalayas to the sunbaked Chihuahuan Desert, Termination Shock brings together a disparate group of characters from different cultures and continents who grapple with the real-life repercussions of global warming. Ultimately, it asks the question: Might the cure be worse than the disease?

In the vein of Neal Stephenson and Jeff VanderMeer, an epic speculative novel from Young Lions Fiction Award–finalist Matt Bell, a breakout book that explores climate change, manifest destiny, humanity's unchecked exploitation of natural resources, and the small but powerful magic contained within every single apple. 

In eighteenth-century Ohio, two brothers travel into the wooded frontier, planting apple orchards from which they plan to profit in the years to come. As they remake the wilderness in their own image, planning for a future of settlement and civilization, the long-held bonds and secrets between the two will be tested, fractured and broken—and possibly healed.

Fifty years from now, in the second half of the twenty-first century, climate change has ravaged the Earth. Having invested early in genetic engineering and food science, one company now owns all the world’s resources. But a growing resistance is working to redistribute both land and power—and in a pivotal moment for the future of humanity, one of the company’s original founders will return to headquarters, intending to destroy what he helped build.

A thousand years in the future, North America is covered by a massive sheet of ice. One lonely sentient being inhabits a tech station on top of the glacier—and in a daring and seemingly impossible quest, sets out to follow a homing beacon across the continent in the hopes of discovering the last remnant of civilization.

Hugely ambitious in scope and theme, Appleseed is the breakout novel from a writer “as self-assured as he is audacious” (NPR) who “may well have invented the pulse-pounding novel of ideas” (Jess Walter). Part speculative epic, part tech thriller, part reinvented fairy tale, Appleseed is an unforgettable meditation on climate change; corporate, civic, and familial responsibility; manifest destiny; and the myths and legends that sustain us all. 

Like everyone else she knows, Mallory is an orphan of the corporate war. As a child, she lost her parents, her home, and her entire building in an airstrike. As an adult, she lives in a cramped hotel room with eight other people, all of them working multiple jobs to try to afford water and make ends meet. And the job she’s best at is streaming a popular VR war game. The best part of the game isn’t killing enemy combatants, though—it’s catching in-game glimpses of SpecOps operatives, celebrity supersoldiers grown and owned by Stellaxis, the corporation that runs the America she lives in.

Until a chance encounter with a SpecOps operative in the game leads Mal to a horrifying discovery: the real-life operatives weren’t created by Stellaxis. They were kids, just like her, who lost everything in the war, and were stolen and augmented and tortured into becoming supersoldiers. The world worships them, but the world believes a lie.

The company controls every part of their lives, and defying them puts everything at risk—her water ration, her livelihood, her connectivity, her friends, her life—but she can’t just sit on the knowledge. She has to do something—even if doing something will bring the wrath of the most powerful company in the world down upon her.
