Alone in the Void: A Teacher's Cosmic Awakening

Ryland Grace awakens from a coma to a nightmare scenario - he's aboard a spaceship called the Hail Mary, his two crewmates are dead, and he has no memory of how he got there. As fragments of memory gradually return, he recalls his former life as a middle school science teacher whose controversial paper on non-water-based life forms had ended his academic career. The existential threat becomes clear: a microscopic organism dubbed "Astrophage" is consuming the sun's energy, threatening to plunge Earth into a catastrophic ice age within decades. The global response was unprecedented - political boundaries dissolved as humanity united under the leadership of Eva Stratt, a Dutch bureaucrat granted almost unlimited authority. Ryland's unconventional theories about life's requirements made him essential to understanding Astrophage, which defied conventional biological understanding. But the most uncomfortable truth emerges with his memories: he had initially refused the mission, choosing self-preservation over duty. Stratt, believing his expertise irreplaceable, had him drugged and launched into space against his will. Imagine waking to discover not just that you're humanity's last hope, but that you never volunteered for the role. How would you reconcile your involuntary heroism with fundamental questions about courage, duty, and redemption? Alone in the vast emptiness of space, Ryland must decide whether to embrace his appointed role or surrender to despair.
