Sully didn’t leave Earth to die; he left to finally live. Escaping the suffocating safety of the Inner System, he stakes everything on a one‑way ticket to Callisto—an indifferent, frozen frontier where the only law is physics. But when his landing craft crumples on descent and his critical supply pods scatter across the jagged regolith, the dream of a solitary homestead collapses into a brutal, immediate fight for oxygen, heat, and calories. Stranded in Jupiter’s shadow with only his loyal dog, Icarus, and a shattered fabrication system, Sully does the only thing he knows how to do: engineer a solution from the wreckage. As he carves a sanctuary into ancient ice and stone, a glint on the horizon forces him to confront a ghost from the very civilization he tried to leave behind. On a world with no atmosphere, no rescue, and no second chances, Sully is about to learn the hardest truth of the frontier: there are no easy buttons—and no soft landings.
