Our take
Goldilocks sends humanity’s future into space with five women and a mission too important to fail. Naomi has trained for years to help colonize a habitable planet, but once the ship leaves Earth behind, technical failures and buried secrets turn survival into something far more uncertain. This science fiction thriller blends ecological collapse, political control, and locked-room tension aboard a mission carrying the last hope for human life.

About the book
New York Times Notable Book and Hugo and Nebula Award Finalist: An epic chronicle of ten immortals over the course of history from an SFWA Grand Master.
The immortals are ten individuals born in antiquity from various cultures. Immune to disease, able to heal themselves from injuries, they will never die of old age—although they can fall victim to catastrophic wounds. They have walked among mortals for millennia, traveling across the world, trying to understand their special gifts while searching for one another in the hope of finding some meaning in a life that may go on forever.
Following their individual stories over the course of human history and beyond into a richly imagined future, "one of science fiction's most revered writers" (USA Today) weaves a broad tapestry that "succeeds admirably" (The New York Times).

About the book
"A fascinating, compulsively readable clash of hardware and ideals" in a stand-alone space opera from an acclaimed sci-fi author (Kirkus Reviews, starred review).
In the distant future, corporations have become sustainable communities with their own militaries, and corporate goals have essentially replaced political ideology.
On a youthful, rebellious impulse, Lawrence joined the military of a corporation that he now recognizes to be ruthless and exploitative. His only hope for escape is to earn enough money to buy his place in a better corporation. When his platoon is sent to a distant colony to quell a local resistance effort, it seems like a stroke of amazing fortune, and Lawrence plans to rob the colony of their fabled gemstone, the Fallen Dragon, to get the money he needs. However, he soon discovers that the Fallen Dragon is not a gemstone at all, but an alien life form that the local colonists have been protecting since it crashed in their area. Now, Lawrence has to decide if he will steal the alien to exploit the use of its inherent biotechnical processes—which far exceed anything humans are capable of—or if he will help the Resistance get the alien home.

About the book
The thrilling start to the Phoenix Legacy space opera: "A new classic! Has the sweep and power of Asimov's Foundation Trilogy" (Jean M. Auel, author of the Earth's Children series).
At the heart of the Concord empire, unrest is festering. Unrecognized by the Elite, the ruling class, an undercurrent of rebellion is surging through the enslaved Bond class. It's a threat that could bring down all of civilization, creating a third Dark Age.
Lord Alexand, first born of the House of DeKoven Woolf, stands to inherit a vast industrial conglomerate along with a seat on the Directorate, the Concord's ruling body. But he sees the writing on the wall and realizes that if the Bonds explode into total rebellion, there will be nothing to inherit, and the toll in human suffering will be beyond calculation. He makes the difficult decision to "die" and join the Society of the Phoenix, a clandestine organization whose existence is known to only a few Directorate Lords, who consider membership treason and punishable by death. But it may be humanity's only hope . . .

An abandoned ship promises refuge, but the dead it carries are only the beginning of the danger.
Salvation Day
Sci-Fi · Horror · First Contact · Space Exploration
Our take
An abandoned ship promises refuge, but the dead it carries are only the beginning of the danger. Salvation Day follows a desperate mission to seize a long-lost exploration vessel, only to uncover a buried threat that turns survival into a race against infection, secrecy, and collapse. This is science-fiction horror built on isolation, contagion, and the suffocating tension of waking something that should have stayed dormant.

About the book
A lethal virus is awoken on an abandoned spaceship in this incredibly fast-paced, claustrophobic thriller.
They thought the ship would be their salvation.
Zahra knew every detail of the plan. House of Wisdom, a massive exploration vessel, had been abandoned by the government of Earth a decade earlier, when a deadly virus broke out and killed everyone on board in a matter of hours. But now it could belong to her people if they were bold enough to take it. All they needed to do was kidnap Jaswinder Bhattacharya—the sole survivor of the tragedy, and the last person whose genetic signature would allow entry to the spaceship.
But what Zahra and her crew could not know was what waited for them on the ship—a terrifying secret buried by the government. A threat to all of humanity that lay sleeping alongside the orbiting dead.
And then they woke it up.

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.

Our take
Humanity’s first contact with superior alien allies comes with a cost, and soldiers are the ones sent to pay it.

Choose your retailer
About the book
Collected in a single volume for the first time, the epic War Dogs trilogy of interstellar war from a master of science fiction.
The Gurus made their presence on Earth known thirteen years ago. Providing technology and scientific insights far beyond what mankind was capable of, they became indispensable advisors and promised even more gifts that we just couldn't pass up.
But they were followed by mortal enemies -- the Antagonists -- from sun to sun, planet to planet, and now the Gurus are stretched thin -- and they need humanity's help.
Our first bill has come due.
Skyrines like Michael Venn have been volunteered to pay the price. They face insidious enemies who were already inside the solar system, establishing a beachhead on Mars.
Venn and his comrades will be lucky to make it out alive -- let alone preserve the future of all of mankind.

Going to Europa in search of life already feels risky.
Europa
Horror · Sci-Fi · Space Exploration
Our take
Going to Europa in search of life already feels risky. Discovering something ancient, trapped, and absolutely not friendly makes it much worse. Europa sends a mission beneath the moon’s frozen surface and into a nightmare waiting in the dark, turning scientific discovery into a brutal fight to survive. Cold, claustrophobic, and full of mounting dread, this is space horror built to keep the pressure on.
Choose your retailer
About the book
The first mission to Europa—Jupiter's enigmatic moon—has landed, and humanity’s darkest fears are about to awaken.
For years, mankind has speculated that this frozen world harbors a hidden ocean twice the size of all Earth’s oceans combined—an ocean potentially teeming with life.
Driven by this tantalizing mystery, they venture forth to unlock its secrets. But what they discover in the abyssal depths is far beyond anything they could have imagined.
Nearly four hundred million miles from Earth, their search for life has succeeded. But in their triumph, they overlook the most terrifying truth: what they have found is something far older and more horrifying than they ever could have conceived. Something has been trapped in the dark for eons—watching, and waiting, for them.
Now, the crew stands at the threshold of unimaginable terror, realizing too late that Hell, in its purest form, is cold.

About the book
DARK SANDS is a finalist for the 2025 Aurealis Awards Best Science Fiction Novel - Australia's most prestigious speculative fiction literary award!

In Cahros, they might have found one.
Among the first wave of specialists deployed to the planet is Tarlo, a young and optimistic biologist who has spent his life dreaming of adventure among the stars. For all his excitement, he feels a little out of his depth – everyone around him seems so much smarter, stronger, and better equipped to deal with whatever challenges may lie ahead.
The team finally sets down on Cahros, but is surprised to learn that the planet is home only to a barren, lifeless desert. All is quiet.
That is, until night falls.
A nightmarish series of events leave Tarlo and the remaining colonists struggling to survive in a world that is so much more than a benign sea of orange. Here on Cahros, nothing is as it seems, and deep within these endless deserts lie untold, deadly secrets.

Humanity’s super-intelligent AI Gods brutally punish breaches in reality, as one young scientist discovers, in this intense and brilliant space opera.
Autistic scientist Yasira Shien has developed a radical new energy drive that could change the future of humanity. But when she activates it, reality warps, destroying the space station and everyone aboard. The AI Gods who rule the galaxy declare her work heretical, and Yasira is abducted by their agents. Instead of simply executing her, they offer mercy – if she’ll help them hunt down a bigger target: her own mysterious, vanished mentor. With her homeworld’s fate in the balance, Yasira must choose who to trust: the gods and their ruthless post-human angels, or the rebel scientist whose unorthodox mathematics could turn her world inside out.
