It's 2026, and catastrophe has struck from an unexpected source. The Alpha Centauri supernova has risen like a second sun, rushing Earth toward its last summer. Floods, fires, starvation, and disease paralyze the planet. In a blue aurora flash of gamma rays, all microchips worldwide are destroyed, leaving an already devastated Earth without communications, transportation, weaponry, or medicine. The disaster sets three groups of survivors on separate quests. Standing at the crossroads is one man, US President Saul Steinmetz, who faces a crucial decision that will affect the fate of his own people--and the world.
