An escape pod drifts through deep space—inside is a broken pilot with a warning from another dimension.

He’s Keith Maker, a preman escaped from the master race. In his universe, the New Men conquered the Commonwealth, enslaving everyone. Now the Dominion has breached the wall between realities to conquer this one.

Star Watch has never faced an enemy so brilliant, fearless, and ruthless— armed with weapons that slice through shields.

But they’ve never faced Maddox.

And he’s not about to let this dimension fall without a fight.

THE LOST DIMENSION is Book 23 in Vaughn Heppner’s million-selling Lost Starship series—a saga of high-stakes space war, alien tech, and do-or-die missions beyond the edge of the galaxy.

Vaughn Heppner

Vaughn Heppner's love for storytelling started in the snowbanks of Canada, where his childhood days were filled with dreams of distant worlds and adventures beyond his frosty front yard. But it wasn’t until a move to sunny Central California that his journey into writing truly began, fueled by an unexpected gift—his very first typewriter. Heppner found himself typing away in early mornings, crafting stories that echoed the same sense of wonder he’d experienced as a child, searching for magic in everyday moments.

It wasn’t long before he dove headfirst into writing full-time, blending his passion for science fiction, fantasy, and adventure. His most well-known works, such as the Lost Starship series, take readers on thrilling intergalactic journeys where humanity’s survival is never guaranteed, and where the characters are as complex as the alien worlds they explore. With an impressive portfolio spanning multiple genres, Heppner’s stories often strike a delicate balance between pulse-pounding action and profound character development.

Heppner's writing is not just about grand battles and high-tech spaceships—it’s about the people behind the machines and the way they struggle, grow, and find purpose in the most chaotic of circumstances. With every novel, Heppner invites readers into universes that are both alien and deeply human. Whether navigating the stars or exploring the depths of the human psyche, his work captures the essence of what it means to face the unknown with courage, and at times, with sacrifice.

When he’s not penning his next great adventure, Heppner can be found enjoying the natural beauty of the world around him, reflecting on his varied experiences. With each new book, Vaughn Heppner reminds us that the greatest journeys are the ones that take us beyond our wildest dreams—and into the very heart of what it means to be human.

From The Lost Starship to his numerous other series, Heppner's work continues to captivate and transport readers to places only he could imagine.

Lost Starship Series

In the cold, uncharted depths of space, a single discovery can ignite a universe of chaos—and the Lost Starship Series unravels that very mystery. Vaughn Heppner takes readers on an extraordinary journey through a galaxy teetering on the brink of war, where long-forgotten technology holds the key to humanity’s future—or its destruction.

The series begins with the discovery of a derelict starship, abandoned for centuries and cloaked in secrets. As a group of explorers stumbles upon this ghostly vessel, they awaken forces far beyond their control. From ancient alien artifacts to dark conspiracies, every twist and turn propels them deeper into a galaxy filled with danger, intrigue, and unfathomable power.

What sets Lost Starship apart is its rich world-building, blending high-stakes space opera with complex character dynamics and ethical quandaries. Heppner’s universe is one of shadows and hidden truths, where alliances are fragile, and survival is never guaranteed. The characters—flawed yet determined—must navigate treacherous political landscapes, face personal demons, and reckon with a past that refuses to stay buried.

At its heart, this series is about discovery—of new worlds, forgotten histories, and the unknown within ourselves. Each page pulls readers further into a sprawling, multi-layered narrative that explores themes of ambition, loyalty, and the price of power. Whether it’s the allure of forbidden technology or the dangers of trusting the wrong allies, the Lost Starship Series constantly challenges its characters, and its readers, to question what it means to be human in a galaxy filled with both wonder and peril.

With breathtaking action, intricate plotlines, and a haunting atmosphere that lingers long after the final page, this series is a deep dive into the dark heart of space exploration. If you’re searching for a story that blends cosmic adventure with profound character journeys, Lost Starship is the voyage you’ve been waiting for.
