Description

There was a great earthquake and the sun became black as sackcloth; every mountain and island were moved out of their places.
Fire rained down from the heavens, consuming whole cities and their populations; dense smoke covered the land like fumes from a furnace.

What do the Yellowstone supervolcano and Mars have in common?

Frank and Helen Gould are brother and sister geophysicists. Following the eruption of the Yellowstone supervolcano, the siblings are cast into a web of survival. Frank struggles in the post- apocalyptic world as North America is thrown into a volcanic winter. The collapsing government disbands NASA, leaving Helen stranded on Mars.

Driven to rescue his sister, Frank works with the Army as it becomes the new governing power. NASA left a rescue rocket at Cape Canaveral, but no one alive knows how to launch it.

Scientific exploration of Mars gives way to life and death struggle. Having lost contact with Earth, Helen searches for the water her team needs to survive. Alone, they realize rescue is not coming.
