The warning arrives too late.

At Polar Station 7, solar monitoring specialist Arjun Mehta watches data shift from anomaly to catastrophe as a massive solar particle event erupts without precedent. Within minutes, a remote lunar installation is forced into emergency lockdown, sealing eighteen crew members inside a bunker designed for twelve.

Outside, geologist Elena Kovács is trapped alone in a rover two kilometers from safety, protected only by thin shielding and a failing battery.

As radiation floods the surface and communication systems degrade, survival becomes a problem of numbers: oxygen margins, battery capacity, radiation dose, and time. Every calculation reveals a narrowing window. Every decision carries irreversible cost.

Inside the bunker, command authority fractures under pressure while an uncomfortable truth emerges - the storm may last longer than their life-support systems can sustain.

Solar Break is a gripping hard-science survival thriller exploring isolation, decision theory, and the fragile mathematics that stand between humanity and space.
