The aliens supervised the loading as anguished parents looked on.
Rothwell locked eyes with the alien, and leaned forward, grinding his knuckles into the desk top. "You know that's impossible. We can't select 100,000 children from every country and assemble them in only six days."
"You will do it." The alien turned to leave.
"Commander Aku! Let me remind you ..."
Aku spun around, eyes flashing. "General Rothwell! Let me remind you that two weeks ago I didn't even know Earth existed, and since accidentally happening across your sun system and learning of your trouble I have had my entire trading fleet of a hundred ships in orbit about this planet while all your multitudinous political subdivisions have filled the air with talk and wrangle.
"I am sorry for Earth, but my allegiance is to my fleet and I cannot remain longer than seven more days and risk being caught up in your destruction. Now, either you accept my offer to evacuate as many humans as my ships will carry, or you don't." He paused. "You are the planet's evacuation coordinator; you will give me an answer."
Rothwell's arms sagged, he sunk back down into his chair, all pretense gone. Slowly he swung around to face the window and the gray ship, standing like a Gargantuan sundial counting the last days of Earth. He almost whispered. "We are choosing the children. They will be ready in six days."
He heard the door open and close. He was alone.
