From Matthew Medney and Don Macnab-Stark the award-nominated creators redefining the limits of sci-fi storytelling.
GUNGNIR Books, the visionary publishing house founded by Heavy Metal’s former CEO Matthew Medney, announced the release of Existence Equation: What is The Price of the Stars? earlier this year and, for the first time, an exclusive look at the upcoming trailer. A bold new science-fiction saga, it dares to ask the ultimate question:
What would you give up for immortality?
Set in the year 2293, the novel follows Liam Kerr, a 17-year-old standing on the brink of The Decision—a rite of passage where every human must choose between two fates:
Upload your consciousness into an emotionless android and live forever among the stars…
or stay human, feel love and connection, and die at 60 in the Cull.
“The Universe: Vast. Expansive. Thrilling.
Earth: Gorgeous. Unique. Finite.
And between them? The Decision.”
In a post-nuclear Earth rebuilt through neural implants and engineered balance, paradise carries a price tag. Liam’s world is one of flawless equilibrium—a society that has traded chaos for order, mortality for progress, and emotion for efficiency. Torn between his love for Brooke and his dream of speed-racing across alien worlds like his hero Larkin Downey, Liam has twelve months to make the choice that will define his existence… and perhaps humanity’s.
“Matthew Medney and Don Macnab-Stark are SFF writers to look out for. The Existence Equation is fast-paced, adventurous fun that powers along the cosmic highway.”
— Paul Cornell, Hugo Award-Nominated, New York Times Bestselling Author (Doctor Who, Fantastic Four, Elementary)
Blending the cerebral depth of Asimov with the visual thrill of Ready Player One, The Existence Equation explores love, technology, and destiny at the edge of the universe. It’s a mind-bending reflection on what it means to be human in a world that no longer needs humans.
“Science fiction has always been about more than spaceships and stars—it’s about the why behind the future,” said Matthew Medney, Founder and Publisher of GUNGNIR. “The Existence Equation is that exploration—a thrilling emotional journey about choice, connection, and the cost of perfection.”
Co-author Don Macnab-Stark added, “We wanted to capture that razor’s edge where coming-of-age meets the cosmos—where a single decision can echo across galaxies. It’s intimate and epic all at once.”
The Existence Equation: The Price of the Stars continues GUNGNIR’s mission to publish daring, thought-provoking fiction that merges grand concepts with deeply human emotion. With this release, GUNGNIR cements itself as the home for modern mythology—stories that ask not just what’s out there, but who we become when we find it.
