About the book
“I realized that I wasn't going to get any sleep (Just one more page... Just one more page…) I'm not just reading words on a page, I'm there… A hell of a ride.” NetGalley reviewer
Humanity is on the brink of annihilation. Only one man can turn the tide.
For centuries, we explored the stars and settled new worlds. But a mysterious alien threat emerged, launching devastating attacks and seizing entire star systems. Every fifty years they come, silent and relentless, before disappearing again into the dark. And as they close in on humanity’s home worlds, one more defeat could mean total extinction.
Captain Jim Garrett joined the navy to fight back. But when a delicate mission ends in madness and mutiny, Garrett takes the blame and his career is left in ruins.
Now, the only thing he commands is a construction site. The CNS Surprise is an experimental warship, half built in the dockyards of Midway Station. Garrett knows the ship inside out, but the navy brass would never let him take the helm, let alone lead her in battle.
But when the aliens strike early, with unexpected ferocity, it’s clear that every ship in the fleet will be needed. And the Surprise could be the only hope of slowing the enemy onslaught.
Garrett is thrust into command for the first time, launching straight into combat. He must unite a maverick crew and master new technologies, as he leads a desperate counterstrike that will decide mankind’s future.
Off Midway Station is a military SF adventure of high-stakes space warfare, nail-biting action, and characters you would gladly follow into battle. A monumental journey of courage, innovation, and the relentless pursuit of survival, it’s perfect for fans of Jack Campbell, David Weber, and Marko Kloos.

Our take
Lieutenant Justin Spencer’s routine CDF tour turns catastrophic when an old enemy resurfaces with devastating force. The League of Sol isn’t just after victory—it’s out for obliteration.

Choose your retailer
About the book
Thirty-five years of peace obliterated in an instant.
Lieutenant Justin Spencer thrives on the adrenaline of piloting Coalition Defense Force fighters, even if it’s just for his annual two-week duty. At home, life is quieter—rooted in love for his wife and daughter. But his decision to join the CDF was purely pragmatic: free education, no real risk. War wasn’t part of the deal.
When an unknown enemy blasts through his cockpit’s shields, everything changes. The League of Sol, remnants of a long-despised regime, resurfaces with brutal intent to annihilate the Terran Coalition.
Now Justin faces a fight for survival, with every simulated drill turning into life-or-death combat. Home isn’t just far—it’s unreachable.
Can Justin outmaneuver destruction, or will the battlefield claim everything he holds dear?

Rose joins a mission of hope, eager to meet the enigmatic Fisone and foster peace. But the dream collapses when she’s taken hostage by a species scarred by betrayal. With tensions rising and alliances crumbling, her captors face a formidable force—Rose’s unyielding resolve. Can strength and wit reshape a broken trust, or will fear plunge two worlds into chaos?

Our take
Drifting through the stars on a fractured mission, the Citadel carries humanity’s last breath.
