About the book
NASA has watched the silent alien ship drift in the asteroid belt for decades, hidden from the public eye, awaiting the day humanity could reach it.
Dr. Jane Holloway is a linguist, not an astronaut, but the chance to board this ship pulls her from academia into a mission of a lifetime. Tasked with decoding any alien messages, she’s both thrilled and wary as her team finally makes contact.
But the ship isn’t empty. A voice—calm, knowing—echoes in Jane’s mind: “You are home.” As her team’s trust fractures and their escape route vanishes, Jane must decipher the alien’s intentions before the entire mission implodes.
Will she unlock its secrets in time, or has NASA sent them into a trap?

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.
