About the book
A hidden conspiracy…
A secret war against mankind…
Something big is coming.
Mankind is branching out, traveling to nearby star systems in search of habitable worlds and valuable resources. Technology continues to advance at a seemingly breakneck pace, but the ability to break the light-speed barrier seems out of reach. Or maybe the conspiracy theorists are right after all, maybe there is a conspiracy between the rich and powerful to hold humanity back.
Second chances don’t come around every day.
Regenerative Therapy can reverse aging, but the costs are staggering. Staff Sergeant Zane Taylor has served for eighteen years, putting his life on the line for the Western Alliance in their ongoing conflicts around the world. But a training accident has derailed his plans for the future and left him without many options.
Willing to do just about anything to get the Regen Therapy that would heal his shattered hip and give him a second chance at life, Zane Taylor took the only option he had left. But no one foresaw what would happen when he joined Exsol, a private security firm offering services to corporate interests on foreign worlds.
There is a secret war brewing. Few know what’s happening, or who is really behind the events shaping life in the Sol system. Join former SSG Zane Taylor as he discovers the alien agenda that is threatening the future of the human race. Foray is the first book in a Conspiracy Sci-Fi series that is loaded with mystery, suspense, and lots of action. Travel through space to the fringe worlds and discover the secrets for yourself. Fans of the X-Files, Firefly, and Stargate will surely love Foray and the entire Alien Agenda series.

Choose your retailer
About the book
There’s something out there. We’ve known about it for a long time. No one knows where it came from or who sent it. But one thing is certain: it wants us to find it.
The S.D.F. Jericho is a new ship, built from a new design, with a single purpose — to retrieve the artifact. She’s still in the early stages of shakedown cruise when the call comes in. The artifact is at the far end of the solar system beyond Saturn’s orbit. Only one ship has ever been built to travel that far, and once they pass Jupiter, they will be completely on their own.
Like every Fleet vessel, the Jericho has a platoon of Space Marines. They are all combat veterans, special forces, and Black Ops commandos. The Senior NCO, Master Sergeant Steel, is fresh from winning the Medal of Honor, but nothing in their training or experience has prepared them for what’s to come.
Join the crew of the Jericho, led by Captain Zeke Darius, as they go on a mission that will change the course of human history forever. Artifact is the first book in a new military sci-fi series by master storyteller Toby Neighbors. Told from the point of view of the characters on the ship and full of action, Artifact will take your imagination to a place it has never gone before. Prepare yourself for an epic series that will instantly become one of your favorites. Artifact (Starship Jericho Book 1) is an all-out thrill ride that will keep you turning pages and leave you anxious for more.

Our take
A restless drifter becomes the unlikely target of forces far beyond Earth.

Choose your retailer
About the book
My name is Kane Hunter, and I never asked to become humanity's last line of defense.
It started with a strange feeling along Nevada's Extraterrestrial Highway—someone watching me. Within hours, my Harley was stolen, I was tossed into a ghost town's jail by a sheriff who wasn't quite human, and an old Paiute chief was whispering about ancient visitors from the stars.
Then I found the Theron—a dormant alien scout ship buried in the desert, waiting for someone with the right genetic markers. Someone like me.
Now I know the truth: an artificial intelligence called the Mindship has infiltrated Earth, using Area 51 as its foothold before a full-scale invasion from Tau Ceti. With a crew of unlikely aliens and androids, I’ll take the fight beyond the solar system’s edge—into enemy territory.
I'm no soldier, just a drifter with an unexpected legacy. But when humanity's survival is on the line, running isn't an option.

A war without a visible enemy forces soldiers to question what they are truly fighting.
Androne
Dystopian · Sci-Fi · Hard Sci-Fi · Military Sci-Fi
Our take
A war without a visible enemy forces soldiers to question what they are truly fighting. Androne follows Sergeant Paxton Arés, a remote pilot deployed after a catastrophic global attack rewrites modern warfare. As rumors, loyalty, and fear collide in an unknowable desert conflict, Paxton’s search for truth becomes personal. This is near-future military science fiction centered on uncertainty, duty, and the consequences of fighting a war no one understands.
Choose your retailer
About the book
Humanity’s new war is an enigma, with an enemy threat beyond all imagination, in this near-future novel of mind-blowing adventure where the fate of the world rests in the choices of one ordinary soldier.
In one terrifying event called the Ninety-Nine, all major military installations on earth were eviscerated. But by whom? Foreign powers, AIs, ETs? Every conceivable adversary was ruled out. Reeling from massive casualties and amid hundreds of conspiracy theories, humanity creates Andrones: bipedal android drones piloted remotely by soldiers who will never again need to be on the field of battle. Newly minted Androne pilot Sergeant Paxton Arés has now been deployed into a fight against an enemy no one understands or has ever seen.
Passing mostly uneventful days patrolling an unidentified desert, Paxton spends time communicating with his pregnant girlfriend back home and reflecting on his impending fatherhood. But as he is drawn deeper into military camaraderie and begins quickly rising up the ranks on the strength of his father’s military legacy, Paxton starts to question the swirling rumors about the nature of the conflict. What he’s encountered in the shifting dunes—something inexplicable, indomitable—fills him with the fear that whatever is out there is destined to win.
Whether it’s curiosity, ambition, or a newfound paternal instinct, Paxton has a driving need to understand the dangerous truths of this strange, invisible war. And the choices he must make have the power to change everything.

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

Our take
Kael Vallen has served the Starlit Covenant as a soldier, but the war makes him question its claims about the people he’s ordered to kill. Defying it could put him against his own brother. A strong match for readers who like military space opera about loyalty, conscience, and rebellion.

About the book
A quest for peace, a bond of brotherhood, and a war that tests them both.

But the war they find themselves in is not the one they were promised.
Thrown into a brutal conflict far from home, Kael is forced to confront the harsh realities that test his loyalty to the Covenant and the ideals he once held dear. Auctor, on the other hand, finds certainty and strength in the midst of chaos, leading him to question his brother's doubts and fears.
As they fight for their beliefs, the bond between Kael and Auctor is put to the ultimate test.

With the reality of war closing in, loyalties are tested and bonds are strained. Kael must decide what kind of man he is willing to become, while Captain Junova must choose between obedience and conscience.
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.

Starship Salvager

Our take
Former soldier Lax VanDunn wants nothing more to do with the empire that bought him as a child and shaped him into a weapon.

Choose your retailer
About the book
War rages between the stars. A ruthless empire crushes all resistance. And one ex-soldier will decide the fate of humanity…
The Paragon empire reduces cities to dust and devastates entire planets. Independent star systems fall one by one… until none remain. Fear keeps the population obedient, but rebels and outlaws hide in the shadows.
After decades of fighting, Lax VanDunn is free. Sold to the Paragon military as a child and shaped into a perfect soldier, war is the only life he’s ever known. When he’s released from the army at last, he swears he’s never going back.
Now, Lax works as a salvager, raiding abandoned spacecraft. When an ancient warship is discovered floating in deep space, Lax realizes it contains a priceless secret that could shatter the Paragon’s grip on the galaxy.
Lax never wanted to be a hero. But the Paragon took everything from him—and now he has a chance to strike back. Can he plan an impossible heist, and lead an inexperienced crew through the ship’s lethal defences? Or will the Paragon snatch away his prize—and humanity’s last chance of freedom?
An absolutely thrilling science-fiction adventure of tension, intrigue and hard-hitting action, Starship Salvager is perfect for fans of James S.A. Corey, Marko Kloos and Craig Alanson.

About the book
Some ships are meant to stay buried.
Veteran Marine Jace Hawthorne thought his warfighting days were over when humanity fell to the alien Overlords.
Now he smuggles outlawed medical tech under the Overlords’ oppressive rule, doing whatever it takes to keep his family safe and alive. But when a routine job leads him to a remote space station blasted to ruins, Jace uncovers a secret the Overlords tried to erase after the war: evidence of ancient alien technology powerful enough to challenge their empire.
The Overlords move fast. His family is imprisoned. Jace is marked for elimination.
Hunted across the stars, Jace follows a trail of shattered clues to a long-buried starship with unimaginable power—a dangerous alien relic from a forgotten war. A ship that could change everything.
To save his family—and humanity’s future—Jace must choose:
keep running… or risk everything to awaken what was meant to stay buried.
He knows one thing for certain. The Overlords messed with the wrong Marine.
