About the book
In the 22nd century, augmented reality is no longer a novelty, but rather a way of life for citizens of Easton. Children are taught at a young age to control the ubiquitous layer of reality known as veneer through a process called reconciliation. Those who learn to reconcile live in a constant state of redefinition, of the world and of themselves. Those who struggle are forced to stand by and watch the world change without them.
For this skill, there are no shortcuts, no special glasses or handheld devices. The power to change comes from within.
Deron Bishop wants to live in the augmented world, to perform the magic of reconciliation like his peers, but controlling the veneer has always been a problem for him. Already resentful of the one thing he could never master, Deron doesn't realize how much he needs the veneer until a violent run-in with a childhood rival puts him in the hospital and robs him of his virtual sight.
Now able to see the world as it truly exists, Deron must choose to abandon Easton or fight his way back to the veneered fantasy of his previous life--a fight not everyone wants him to win.
Join Deron, his friends, and his enemies as they discover the truths that will be revealed when the virtual veil finally drops.

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

Some signals carry more than information, pulling old loyalties back into the light.
No One Left Behind
Sci-Fi · Galactic Empire · Space Exploration
Our take
Some signals carry more than information, pulling old loyalties back into the light. No One Left Behind follows Edgar Bryce, a former soldier drawn out of isolation by a forbidden distress call from prisoners abandoned beyond the border. This military science fiction series centers duty, sacrifice, and found family, tracing one man’s resolve to honor promises in a fragile postwar galaxy.
Choose your retailer
About the book
Edgar Bryce thought his war was over. Then he heard the signal.
Once a decorated soldier, Bryce now roams the stars as a freelance prospector, trading danger for solitude. The battles may be behind him, but peace has never come easy. He’s drifting until a strange signal pulls him off course.
A hidden transmission. A plea for help. A distress call from human prisoners long thought lost.
The authorities won’t act. Peace is too fragile. Diplomats would rather look away. But Bryce remembers what it means to wear the uniform and the unspoken vow that comes with it.
He’ll have to do the impossible: form a team, cross the border, and bring them home.
Because some promises don’t expire. And some missions… choose you.

A disgraced presidential candidate dies and leaves behind a final command that refuses to make sense.
Cleave the Sparrow
Dystopian · Sci-Fi
Our take
A disgraced presidential candidate dies and leaves behind a final command that refuses to make sense. In the aftermath, his apprentice Tom and ruthless campaign manager Shelly follow a trail that bends satire into philosophy and politics into farce. As reality fractures, certainty becomes the enemy. Cleave the Sparrow is a darkly comic literary novel that interrogates power, belief, and the stories people tell to survive chaos.

12,000+ COPIES SOLD • 1,000+ FIVE STAR RATINGS • 2,000,000+ PAGES READ ON KINDLE UNLIMITED • 2025 LITERARY TITAN GOLD BOOK AWARD WINNER
"Uproariously funny and incredibly prescient."
—Hollywood Book Reviews
"Daring, unpredictable, and utterly consuming."
—San Francisco Book Review
"Pushes satire to the absolute limit, and then some."
—The Independent Review of Books
Wilder Crick, the worst presidential candidate in history, is dead.
Now his reluctant apprentice Tom and ruthless campaign manager Shelly must carry out his final order—a bizarre, posthumous search for the true, hidden nature of reality.
"Some books tell a story," writes Literary Titan's Priscilla Evans. "Others drag you into a chaotic, unrelenting experience that scrambles your brain and leaves you questioning everything. Cleave The Sparrow is for people who enjoy satire so sharp it draws blood, philosophy so deep it makes your head hurt, and humor so dark you feel guilty laughing. It’s for fans of Catch-22, Infinite Jest, and Dr. Strangelove. It’s for anyone who has ever looked at the world and thought: This can’t be real. Because maybe, just maybe, it isn’t."
TL;DR: Darkly comic, wildly original, and impossible to forget, Cleave the Sparrow is for readers who crave mind-bending fiction that makes you laugh, wince, and question everything you thought was real.

A hush falls over Earth as invisible barriers appear at random. Cars crash into them; trees are sliced in half, but nothing prepares humanity for what comes next.

The road won’t be easy, and they have no choice but to venture past the Glass. What they find on the other side is another story.

About the book
"Science fiction at its best, a realistic tale of exploration and danger, written by a man who knows the details of deep-sea exploration firsthand." —Ben Bova, Hugo Award-wining author
With a crew of seven, the Challenger sea lab submerges three miles below the waves for a one-year mission to study the hidden world of the deep black sea. How is it that sea animals can live and reproduce in water that should boil them on the thermal vents known as "black smokers?" Superheated water that is full of toxins and heavy metals and contains almost no oxygen should be void of life on planet Earth—and yet it is teeming with it. The answer to the puzzle lies in the bacteria.
Researcher Ted Bell is a NASA scientist with his own agenda: getting humans to Mars. When he purposefully infects a member of the crew in an attempt to harness the power of the Deinococcus radiodurans bacteria, he quickly loses control and unleashes a terrifying new creature. His botched experiment quickly becomes a battle for survival—three miles below the surface.
With the research vessel nearing catastrophic failure, and terrifying alien life forms running wild through the ship, the crew must figure out a way to battle something that is no longer human while trying desperately to reach the surface alive.
"Crichton at his best is the main author who comes to mind as a comparable influence when reading Deep Black Sea . . . The informative and fascinating science that fills each page really elevates this book to a higher grade." —Horror Novel Reviews

Thousands of years in the future, Earth is a desolate ruin. The first human ship to return in millennia discovers an abandoned wasteland inhabited only by a few degenerate or mutated human outcasts. But among them is a boy of immense native intelligence and determination who is captured, taken in, and educated, and disappears--to grow up to become the force behind a plan to make Earth flower again. He is, if not immortal, at least very long-lived, and he plans to build an independent power base out in the galaxy and force the galactic empire to devote centuries and immense resources to the restoration of the ecology of Earth.

About the book
Our final reckoning; Earth's introduction to the alien race we have always feared would find us. They are bent on our complete enslavement through brutal conquest, and they seem unstoppable. The violent end of all humanity begins at a Widespread Panic concert at Red Rocks. Thousands of humans are suddenly transported to an enormous alien vessel where they are pitted against each other in gladiatorial death matches for the entertainment of a Master Race of reptilian monsters.
Those that are not worthy of battle are eaten.
Enter our unlikely hero, Michael Talbot, a college student taken hostage from Red Rocks. Through nerve, wit, and blind luck, he rises to the top of the Arena Match Rankings, scoring better accommodations and collecting prizes—human women given as "spoils" to the victor of each match.
Meanwhile, on Earth, the U.S. Government cautiously approaches the spacecraft orbiting Jupiter, hoping for a diplomatic solution. But Paul Ginson, Mike's childhood friend, has other plans. He is building a militia, certain that an all-out alien invasion is the more likely outcome.
A great place to enter the Tufo universe, this is the introduction to some of Mark's most endearing characters and one of his best-loved series. The reader is transported through candid, personal anecdote then held spellbound by incredibly heroic, often graphic scenarios. Written with humor and courage, deeply insightful and terrifying, this sweeping epic explores all it means to be human.

The Shattered Star is an emotionally-charged military science fiction novel that explores the complexities of loyalty, conscience, and the cost of obedience in the face of war.
For fans of The Forever War, The Expanse, and character-driven space operas, this book combines action-packed military sci-fi with themes of philosophy, betrayal, and the essence of humanity.
