In the aftermath of a cataclysmic collision of an immense asteroid with the Earth, amid worldwide tsunamis, volcanic eruptions and impenetrable ash clouds, most forms of life succumbed. Yet out of the rubble of the scorched, scarred, frozen planet, a few groups of human stragglers managed to survive and begin rebuilding. The ruptured crust of the Earth had unleashed a toxic acidic volcanic soup that made the oceans inhospitable to sea life, destroyed much of the Amazon rain forest, and triggered a new ice age. Yet a decade after the asteroid impact, a decline in volcanic activity loomed as a bright spot on the horizon. Scores of colonies survived and adapted, saving some vegetation and animals to build a better world, striving for a new Eden. But their best intentions appeared threatened when the world’s largest super volcano began smoldering with increasing ferocity, signaling an eruption that this time could annihilate the human race.
