The Threshold Protocol: Mission Briefing

The four missions at the centre of the series, set out as the briefing document the crews actually worked from — Artemis outbound at 31.2 light-years, the gravitational anomaly near Jupiter, the Prometheus probe returning with a recursive signal, and the borehole through twenty kilometres of Europan ice.

About the Author
Emily Carter
Emily Carter
Cartographer of Curved Spacetime

Emily Carter writes hard science fiction about people who have to make irreversible decisions with incomplete data, very far from help. Her novels put engineers, physicists and commanders at the center of history, and hold the physics to the same standard as the drama.

The Threshold Protocol series runs from a generational starship losing propulsion beyond mapped space, to a classified anomaly near Jupiter, to a probe that comes back from the dark carrying something humanity cannot safely refuse, to an ocean under twenty kilometres of Europan ice where humanity turns out to be the dangerous one.

No space fantasy shortcuts, no hand-waved drives. Just the fragile mathematics of survival at the edge of what we understand.
