From the Audie-nominated narrator of The Martian. In eleven years' time, a million members of an alien race will arrive at Earth. Years before they enter orbit, their approach will be announced by the flare of a thousand flames in the sky, their ships' huge engines burning hard to slow them from the vast speeds needed to cross interstellar space. These foreboding lights will shine in our night sky like new stars, getting ever brighter until they outshine even the sun, casting ominous shadows and banishing the night until they suddenly blink out.

For dinosaurs, it was a big rock. For humans: Coronal Mass Ejection (CME). When the Earth is hit by the greatest CME in recorded history (several times larger than the Carrington Event of 1859), the combined societies of the planet's most developed nations struggle to adapt to a life thrust back into the Dark Ages. In the United States, the military scrambles to speed the nation's recovery on multiple fronts including putting down riots, establishing relief camps, delivering medical aid, and bringing communication and travel back on line. Just as a real foothold is established in retaking the skies (utilizing existing commercial aircraft supplemented by military resources and ground control systems), a mysterious virus takes hold of the population, spreading globally over the very flight routes that the survivors fought so hard to rebuild.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day.

Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.
