They hit the train for credits.

They left with a weapon that could rewrite time.

Rix Varn is a battle-scarred pilot with a chip on his shoulder and a bounty on his head. Grix is his half-mechanical partner with feathers, firepower, and a bad habit of stealing from people who take themselves too seriously. Together, they fly the Black Vow—the fastest rustbucket this side of Saturn—and they only take jobs no one else is crazy enough to touch.

So when a plasma train loaded with high-grade tech comes screaming across Hyperion’s skies, they do what outlaws do best: board it, rob it, and vanish.

But this time, they steal something they shouldn’t have—a living core that pulses with forgotten science and impossible power. The kind of tech the Astrogarch syndicates bury under blacksites and erase from history. The kind of tech that wakes up when you touch it.

Now Rix, Grix, and Kael—the ghost from Rix’s past—are being hunted across the stars by warships, mercenaries, and something far older. Something that’s watching.

It’s not about surviving the heist anymore.

It’s about surviving what comes after.

For fans of Firefly, The Expanse, and Red Rising, this fast-paced, standalone sci-fi adventure is bursting with sharp dialogue, cinematic action, and just enough trouble to fill a black hole.
