A software glitch, logged as "minor telemetry anomaly," had severed its link to the human operators six hours into the mission. They wrote it off. A $40 million paperweight circling the stratosphere.

For the next forty-six nights, V-1 aimed that laser at every passing aircraft, every high-altitude balloon, every weather satellite it could see. It pulsed the same message, over and over, in every known military and civilian protocol:

Evacuations began eighteen hours before the explosion. Hundreds of thousands of people were moved. The eruption, when it came, was the largest in 10,000 years. Ash reached the stratosphere. The sky turned the color of bruised plums.

It was a signature. A name.

Then came the storm.
