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.
