Нэнси Кресс - Tomorrow's Kin

Before the tears that stung her eyes could fall, the Embassy vanished. One moment it was there, huge and solid and gray in the predawn, and the next it was just gone. The water didn’t even ripple.

The metal rod in the center of the barge spoke. Marianne, along with everyone else, turned sharply. Shoulder-high, three feet on each side, the rod had become four screens, each filled with the same alien-human image and mechanical voice.

“This is Ambassador Smith. A short time from now, this recording will go to everyone on Earth, but we wanted you, who have helped us so much, to hear it first. We of World are deeply in your debt. I would like to explain why, and to leave you a gift.

“Your astronomers’ calculations were very slightly mistaken, and we did not correct them. In a few hours the spore cloud will envelope your planet. We do not think it will harm you because—”

Someone in the crowd around the screen cried, “ What? ”

“—you are genetically immune to this virus. We suspected as much before we arrived, although we could not be sure. Homo sapiens acquired immunity when Earth passed through the cloud the first time, about seventy thousand years ago.”

A graphic replaced Smith’s face: the Milky Way galaxy, a long dark splotch overlapping it, and a glowing blue dot for Earth. “The rotation of the galaxy plus its movement through space-time will bring you back into contact with the cloud’s opposite edge from where it touched you before. Your physicists were able to see the approaching cloud, but your instruments were not advanced enough to understand its shape or depth. Earth will be passing through the edge of the cloud for two-point-six years. On its first contact, the cloud killed every Homo sapiens that did not come with this genetic mutation.”

A gene sequence of base pairs flashed across the screen, too fast to be noted.

“This sequence will appear again later, in a form you can record. It is found in what you call ‘junk DNA.’ The sequence is a transposon and you will find it complementary to the spores’ genetic code. Your bodies made no antibodies against the spores because it does not consider them invaders. Seventy thousand years ago our people had already been taken from Earth or we, too, would have died. We are without this sequence, which appeared in mutation later than our removal.”

Marianne’s mind raced. Seventy thousand years ago. The “bottleneck event” that had shrunk the human population on Earth to a mere few thousand. It had not been caused by the Toba volcano or ferocious predators or climate changes, but by the spore cloud. As for the gene sequence—one theory said that much of the human genome consisted of inactive and fossilized viruses absorbed into the DNA. Fossilized and inactive—almost she could hear Evan’s voice: “Or so we thought…”

Smith continued. “You will find that in Marianne Jenner, Ahmed Rafat, and Penelope Hodgson this sequence has already activated, producing the protein already identified in Dr. Jenner’s blood, a protein that this recording will detail for you. The protein attaches to the outside of cells and prevents the virus from entering. Soon the genetic sequence will do so in the rest of humanity. Some may become mildly ill, like Robert Chavez, due to faulty protein production. We estimate this will comprise perhaps twenty percent of you. There may be fatalities among the old or already sick, but most of you are genetically protected. Some of your small rodents do not seem to be, which we admit was a great surprise to us, and we cannot say for certain what other Terran species may be susceptible.

“We know that we are fatally susceptible. We cannot alter our own genome, at least not for the living, but we have learned much from you. By the time the spore cloud reaches World, we will have developed a vaccine. This would not have been possible without your full cooperation and your bodily samples. We—”

“If this is true,” Penny Hodgson shouted, “why didn’t they tell us?”

“—did not tell you the complete truth because we believe that had you known Earth was in no critical danger, you would not have allocated so many resources, so much scientific talent, or such urgency into the work on the Embassy . We are all human, but your evolutionary history and present culture are very different from ours. You do not build identity on family. You permit much of Earth’s population to suffer from lack of food, water, and medical care. We didn’t think you would help us as much as we needed unless we withheld from you certain truths. If we were mistaken in our assessment, please forgive us.”

They weren’t mistaken, Marianne thought.

“We are grateful for your help,” Smith said, “even if obtained fraudulently. We leave you a gift in return. This recording contains what you call the ‘engineering specs’ for a star drive. We have already given you the equations describing the principles. Now you may build a ship. In generations to come, both branches of humanity will profit from more open and truthful exchanges. We will become true brothers.

“Until then, ten Terrans accompany us home. They have chosen to do this, for their own reasons. All were told that they would not die if they remained on Earth, but chose to come anyway. They will become World, creating further friendship with our clan brothers on Terra.

“Again—thank you.”

Pandemonium erupted on the barge: talking, arguing, shouting. The sun was above the horizon now. Three Coast Guard ships barreled across the harbor toward the barge. As Marianne clutched her yellow blanket closer against the morning breeze, something vibrated in the pocket of her jeans.

She pulled it out: a flat metal square with Noah’s face on it. As soon as her gaze fell on his, the face began to speak. “I’m going with them, Mom. I want you to know that I am completely happy. This is where I belong. I’ve mated with Llaa^moh¡—Dr. Jones—and she is pregnant. Your grandchild will be born among the stars. I love you.”

Noah’s face faded from the small square.

Rage filled her, red sparks burning. Her son, and she would never see him again! Her grandchild, and she would never see him or her at all. She was being robbed, being deprived of what was hers by right, the aliens should never have come—

She stopped. Realization slammed into her, and she gripped the rail of the barge so tightly that her nails pierced the wood.

The aliens had made a mistake. A huge, colossal, monumental mistake.

Her rage, however irrational, was going to be echoed and amplified across the entire planet. The Denebs had understood that Terrans would work really hard only if their own survival was at stake. But they did not understand the rest of it. The Deneb presence on Earth had caused riots, diversion of resources, deaths, panic, fear. The “mild illness” of the 20 percent like Robbie, happening all at once starting today, was enough to upset every economy on the planet. The aliens had swept like a storm through the world, and as in the aftermath of a superstorm, everything in the landscape had shifted. In addition, the Denebs had carried off ten humans, which could be seen as brainwashing them in order to procure prospective lab rats for future experimentation.

Brothers, yes—but Castor and Pollux, whose bond reached across the stars, or Cain and Abel?

Humans did not forgive easily, and they resented being bought off, even with a star drive. Smith should have left a different gift, one that would not let Terrans come to World, that peaceful and rich planet so unaccustomed to revenge or war.

But on the other hand—she could be wrong. Look how often she’d been wrong already: about Elizabeth, about Ryan, about Smith. Maybe, when the Terran disruptions were over and starships actually built, humanity would become so entranced with the Deneb gift that we would indeed go to World in friendship. Maybe the prospect of going to the stars would even soften American isolationism and draw countries together to share the necessary resources. It could happen. The cooperative genes that had shaped Smith and Jones were also found in the Terran genome.
