A devastating cascade of earthquakes strike New Mexico's forgotten fault lines.

Quakes spread across the continent.

Fumeroles emerge in unknown hotspots.

The Earth shakes and begins the process of opening the Rio Sea, where once, in prehistory, a great ocean thrived.

Oceans heave as the Ring of Fire bursts with increased activity.

Continental plates shift, rip apart, and bounce against each other.

Oceans heave as the Ring of Fire bursts with increased activity.

Disaster builds on disaster.

Continental plates shift, rip apart, and bounce into each other.

Everyone thought Arizona and New Mexico would be forever safe from earthquakes, volcanoes, and shifting water tables.

Only, they aren't.

As the continental plates shift, so do the lives of Amber and Alex as they struggle to find firm ground in the altered landscape.

Aftershocks spread through the land, changing communities, forcing most to flee for their lives.

The world as Amber and Alex knew crumbles around them.

Family and friends missing.

Communication relays fail.

There is no power, or phone service, with remaining fuel reserved for military missions.

Society as they knew it, teeters on the brink of collapse.

Established communities melt apart, as walls between human population groups soar.

Men, women, and cultures clash as if they had never learned to live together in peace.

Together, survivors must build a future in a tangled environment of fear, hunger, cold, and desolation.
