Beneath the crushing depths of an alien ocean, apprentice submarine mechanic Jake Stone learned early that survival is earned. Orphaned after his parents vanished beyond the colony’s borders, he grew up piloting robotic “Jumpers” across the seafloor, patching ancient structures and dreaming of escape. When he is offered a job aboard a cargo submarine, it feels like salvation. Instead, it drags him into the obsessions of a relentless captain and his defiant daughter, both hunting ancient technology buried in the abyss, relics powerful enough to decide humanity’s fate. Hounded by ruthless treasure hunters and haunted by creatures once whispered of as myth, Jake must confront the ghosts of his past and the truth rising from the ocean floor before the deep claims them all.
