About the book
A discovery that wasn’t meant to happen.
On a timeline that shouldn’t exist.
When Reid Walton, an unacclaimed community college history professor and obscure conspiracy author, is invited to join a billionaire’s mysterious science project as a history expert, he has no idea why they chose him, or what to expect. Sequestered in a secluded mountain laboratory, he is introduced to their mind-blowing venture: stable time travel, safe enough for a public attraction.
And they already have a working vehicle!
On the heels of this staggering revelation comes another. The time travel technology is suspected of being stolen property. If so, stolen from where? The faster-than-light particles that make the time machine work exist nowhere in the known world except the enigmatic inventor’s possession, who refuses to disclose his source. Could they have come from the future?
With help from the lab crew led by the genius and resourceful Dr. Sara Dearborn, Reid digs for answers to the mystery he was hired to solve. But uncovering the truth turns perilous. Reid finds there is much more at stake than just a time machine, and flushing out his quarry may get them all killed – and rip the timeline apart.
Catapulted across history, Reid, Sara, and their allies must survive alternate dimensions, Nazis, Vikings, and a psychopath willing to destroy anyone and anything, even the timeline itself, if it prevents him from his prize. A prize that offers power more seductive than just time travel. For a deadly price.

Our take
Fourteen-year-old prodigy Ethan Cole buys an old Apple II and discovers the vanished research of a Cold War physicist whose unsanctioned project could reshape modern physics.

About the book
At the end of the Cold War, a physicist at Oak Ridge National Laboratory was pursuing an unsanctioned project that could reshape modern physics. Then he vanished — his lab seized, his research classified, his name erased from the record.
Thirty-five years later, Ethan Cole — fourteen years old, a prodigy, more capable than engineers twice his age — purchases the physicist's old Apple II at an estate sale. Inside, he finds hand-built hardware, encrypted disks, and notebooks full of equations thought to have disappeared with the physicist. The work was revolutionary and ahead of its time. Decades ahead.
Fully realizing the physicist's vision wasn't possible with 1980s technology. But three decades of advancement have closed the gap — and Ethan has the skills to finish what was started. The question is whether he should. The last person who tried never came home.
Sometimes going back is the only way forward.

The Feed imagines a world where constant connection collapses into fear, hunger, and suspicion.
The Feed
Dystopian · Techno-Thriller · Time Travel
Our take
The Feed imagines a world where constant connection collapses into fear, hunger, and suspicion. Tom and Kate survive the fall of the technology that once linked every thought and memory, but their fragile safety breaks when their young daughter disappears. This dystopian sci-fi thriller blends post-collapse survival, parental desperation, and a chilling question of identity and trust.
Choose your retailer
About the book
Nick Clark Windo's "The Feed examines our addiction to technology through the lens of a bleak dystopia . . . A deft and extremely clever work of sci-fi."*
The Feed is accessible everywhere, by everyone, at any time. It instantaneously links us to all information and global events as they break. Every interaction, every emotion, every image can be shared through it; it is the essential tool everyone relies on to know and understand the thoughts and feelings of anyone and everyone else in the world.
Tom and Kate use the Feed, but Tom has resisted its addiction, which makes him suspect to his family. After all, his father created it. But that opposition to constant connection serves Tom and Kate well when the Feed collapses after a horrific tragedy shatters the world as they know it.
The Feed's collapse, taking modern society with it, leaves people scavenging to survive. Finding food is truly a matter of life and death. Minor ailments, previously treatable, now kill. And while the collapse has demolished the trappings of the modern world, it has also eroded trust. In a world where survival of the fittest is a way of life, there is no one to depend upon except yourself . . . and maybe even that is no longer true.
Tom and Kate have managed to protect themselves and their family. But then their six-year-old daughter, Bea, goes missing. Who has taken her? How do you begin to look for someone in a world without technology? And what happens when you can no longer even be certain that the people you love are really who they claim to be?

Our take
A Nebula Award winner, Timescape follows scientists in a collapsing 1998 Earth who try to send a warning into 1962, where researcher Gordon Bernstein begins noticing impossible interference patterns in a lab experiment.

About the book
Winner of the 1980 Nebula Award, Timescape has since become a classic of the science fiction genre, combining hard science, bold speculation, and human drama—a challenging and triumphant tale told by a master storyteller.
1998. Earth is falling apart, on the brink of ecological disaster. But in England a tachyon scientist is attempting to contact the past, to somehow warn them of the misery and death their actions and experiments have visited upon a ravaged planet.
1962. JFK is still president, rock 'n' roll is king, and the Vietnam War hardly merits front-page news. A young assistant researcher at a California university, Gordon Bernstein, notices strange patterns of interference in a lab experiment. Against all odds, facing ridicule and opposition, Bernstein begins to uncover the incredible truth . . . a truth that will change his life and alter history . . . the truth behind time itself.

About the book
LOCUS AWARD WINNER • The multiple-award-winning science fiction master continues the epic adventure that began in Hyperion, where the opening of the Time Tombs threatens to alter the very fabric of time and space, in the second novel in the Hyperion Cantos.
“One of the finest achievements of modern science fiction.”—The New York Times Book Review
The shadow of war has fallen on the Web. In the corridors of power on Tau Ceti Center, chaos reigns. Out of reach from the clashing empires, the artificial intelligences of the TechnoCore manipulate everyone and everything. And on Hyperion itself, where battle rages in the skies and on the streets, the mysterious Time Tombs are opening. And the secrets they contain mean that nothing—nothing anywhere in the universe—will ever be the same.

Time Salvager
Sci-Fi · Space Opera · Time Travel
Our take
A condemned criminal makes his living stealing from the past until one forbidden rescue turns a routine mission into a future-shattering mistake. Time Salvager fits sci-fi readers who want time travel under pressure, ruined Earth survival, outlaw tension, and a fast-paced story where one impossible choice puts all of humanity’s rules at risk.
Choose your retailer
About the book
Time Salvager: a fast-paced time travel adventure from Wesley Chu, the award-winning author of The Lives of Tao.
Convicted criminal
James Griffin-Mars is no one's hero. In his time, Earth is a toxic, abandoned world and humans have fled into the outer solar system to survive, eking out a fragile, doomed existence among the other planets and their moons. Those responsible for delaying humanity's demise believe time travel holds the key, and they have identified James, troubled though he is, as one of a select and expendable few ideally suited for the most dangerous job in history.
James is a chronman, undertaking missions into Earth's past to recover resources and treasure without altering the timeline. The laws governing use of time travel are absolute; break any one of them and, one way or another, your life is over. Most chronmen never reach old age; the stress of each jump through time, compounded by the risk to themselves and to the future, means that many chronmen rapidly reach their breaking point, and James Griffin-Mars is nearing his.
On a final mission that is to secure his retirement, James meets Elise Kim, an intriguing scientist from a previous century, who is fated to die during the destruction of an oceanic rig. Against his training and his common sense, and in violation of the chronmen's highest law, James brings Elise back to the future with him, saving her life, but turning them both into fugitives. Remaining free means losing themselves in the wild and poisonous wastes of Earth, somehow finding allies, and perhaps discovering what hope may yet remain for humanity's home world.

Time becomes a battlefield where loyalty has no fixed point.
The Corridors of Time
Sci-Fi · Hard Sci-Fi · Space Opera · Time Travel
Our take
Time becomes a battlefield where loyalty has no fixed point. In The Corridors of Time, imprisoned ex-marine Malcolm Lockridge accepts a mysterious offer that thrusts him into a war waged across centuries between rival factions. As he moves through shifting historical eras, the lines between good and evil blur. A classic science fiction adventure of temporal conflict, destiny, and moral uncertainty.
Choose your retailer
About the book
A young man from the twentieth century is recruited to fight in a war that rages throughout time in this classic science fiction adventure from a multiple Hugo and Nebula Award–winning master.
College student, ex-marine, and martial artist Malcolm Lockridge is in prison awaiting his trial for murder when he receives an unexpected visit from an extraordinarily beautiful woman named Storm. Claiming to be a representative of the Wardens, a political faction from two thousand years in the future, Storm offers the astonished young man a proposition: freedom in return for his assistance in recovering an unspecified lost treasure. But it is not long before Malcolm realizes that, in truth, he's been recruited as a soldier in the Wardens' ongoing war against their rivals, the Rangers. And this war is different from any that has ever been fought, because the battlefield is not a place but time itself.
Traveling backward and forward through corridors connecting historical epochs separated by thousands of years, Malcolm is soon embroiled in a furious conflict between the forces of good and minions of evil. But the deeper he is pulled into this devastating time war, the clearer Malcolm's ultimate role in humankind's destiny becomes, causing the troubled young soldier from the twentieth century to question whether he's been chosen to fight on the side of good or evil . . . and if such a distinction even exists.

Seven strangers wake up after the end of the world and realize the apocalypse has left behind more questions than corpses.
The Apocalypse Seven
Dystopian · Sci-Fi · First Contact · Time Travel
Our take
Seven strangers wake up after the end of the world and realize the apocalypse has left behind more questions than corpses. With entire populations gone, weather gone feral, and the world turning weirder by the hour, this ragtag group has no choice but to start hunting for answers. The Apocalypse Seven mixes post-apocalyptic mystery, offbeat humor, and found-family into a story that feels equal parts cozy and deeply strange.
Choose your retailer
About the book
Seven strangers attempt to figure out how they missed the end of the world in this cozy apocalypse story by the author of The Spaceship Next Door.
"Doucette's seven aren't just magnificent—they're also entertaining as hell." —Scott Sigler, New York Times–bestselling author of the Infected trilogy
This is the world ends, not with a bang, but a whatever . . .
The whateverpocalypse. That's what Touré, a twenty-something Cambridge coder, calls it after waking up one morning to find himself seemingly the only person left in the city. Once he finds Robbie and Carol, two equally disoriented Harvard freshmen, he realizes he isn't alone, but the name sticks: Whateverpocalypse. But it doesn't explain where everyone went. It doesn't explain how the city became overgrown with vegetation in the space of a night. Or how wild animals with no fear of humans came to roam the streets.
Add freakish weather to the mix, swings of temperature that spawn tornadoes one minute and snowstorms the next, and it seems things can't get much weirder. Yet even as a handful of new survivors appear—Paul, a preacher as quick with a gun as a Bible verse; Win, a young professional with a horse; Bethany, a thirteen-year-old juvenile delinquent; and Ananda, an MIT astrophysics adjunct—life in Cambridge, Massachusetts gets stranger and stranger.
The self-styled Apocalypse Seven are tired of questions with no answers. Tired of being hunted by things seen and unseen. Now, armed with curiosity, desperation, a shotgun, and a bow, they become the hunters. And that's when things truly get weird.
"The adventure I've been looking for! Never once did I know what to expect, and I loved being proved wrong at every turn. Far more mind-bending than a book this fun has any right to be." —Zack Jordan, author of The Last Human
"[A] riveting postapocalyptic outing. . . . Doucette's vibrant prose and unique premise make for an enticing adventure." —Publishers Weekly

About the book
From the New York Times bestselling author of Tokyo Ever After comes “an endearing, lightly magical romantic comedy” (Kirkus Reviews) about a girl who starts receiving letters from the love of her life—writing to her from years in the future.
What if your true love could write to you from the future?
Seventeen-year-old Emma Nakamura-Thatcher doesn’t believe in love, not after her parents’ bitter divorce. So when she attends the festival of Tanabata, her wish is simple: proof that love is real and can last.
Emma thinks little of her wish…until she finds a note from someone claiming to be her greatest love writing to her from the future. It has to be a prank, right? But as the notes pour in, each revealing secrets only she knows, Emma is forced to accept the impossible: This is really happening. Someone is actually reaching out to her from across time.
But who? Ezra, the musical prodigy who makes her pulse race? Theo, the literal boy next door who’s known her since childhood? Or Colin, the overly confident, overly handsome, overly rich kid she meets while cleaning his mega-mansion?
As Emma races to uncover the identity of the letter writer, she’ll discover that love is more than real—it’s the most powerful force in the universe. And it’s been waiting for her all along.

About the book
The last survivors. The last chance. The last leap through time…
Finalist, 2025 Hoffer Book Awards Grand Prize
Rated 9.5/10 by Publishers Weekly's BookLife Prize in Fiction
For fans of The Murderbot Diaries, The Martian, and Dark Matter comes a fast-paced, emotional journey through love, loss, and redemption set in a future collapsing under its own weight.
Fifty years from now, the last humans hide beneath glass domes while swarms of microdrones tear at the last defenses of a drowning world. Inside Eden-17, a dying scientist and her lifelong love cling to hope—and each other—while a sarcastic, duct-taped AI named Madders keeps the biodome online.
But time is running out. Power is fading. Options are gone. They face one impossible choice: shut down everything—including Madders—to send one of them back in time, leaving the other behind to face the end.
Alone.
Diego refuses to go. But Isabel knows what’s coming. He has to do it. For her.
Thirty-five years earlier, Isabel’s life is unraveling. Her marriage is over. Her future is empty. Then a stranger shows up with a haunted gaze and a warning she doesn’t want to hear. He's not supposed to talk to her, but he knows what’s coming. And what she does next will determine everything.
As the multiverse buckles under the weight of its own contradictions, a far-future Madders peers across timelines: at a physicist chasing the ghost of a time machine, a woman whose quiet choices could ignite revolution, and a man bound to her by love, grief, and time itself.
Rewrite the past without consequences? Go ahead. Try.
Lyrical and unflinching, Hive is the award-winning first book in the Madders in Time series—an emotional, character-driven sci-fi thriller where time travel isn’t a gimmick but a reckoning. Follow the tenuous thread woven through fractured timelines, fragile hearts, and white-knuckle suspense. Step into a world where time is both the enemy and the only option.
Hope’s a hell of a thing to weaponize—especially when it’s all you have left.

Our take
Achilles and Hector unite against the gods who control their fates as Olympus itself becomes a battlefield. While divine power crumbles, humanity faces annihilation from its own creations.

About the book
Beneath the gaze of the gods, the mighty armies of Greece and Troy met in fierce and glorious combat, scrupulously following the text set forth in Homer's timeless narrative. But that was before twenty-first-century scholar Thomas Hockenberry stirred the bloody brew, causing an enraged Achilles to join forces with his archenemy Hector and turn his murderous wrath on Zeus and the entire pantheon of divine manipulators; before the swift and terrible mechanical creatures that catered for centuries to the pitiful idle remnants of Earth's human race began massing in the millions, to exterminate rather than serve.
And now all bets are off.
