A young woman, five months pregnant, who “wanted to give my baby a better life.” She did not say what her previous life had been, but there were bruises on her arms and legs.
A pair of thirty-something brothers with restless, eager-for-adventure eyes.
A middle-aged journalist with a sun-leathered face and impressive byline, recorders in her extensive luggage.
And, most unexpected, a Terran physicist, Dr. Nathan Beyon of Massachusetts Institute of Technology.
Nine Terrans willing to go to the stars.
A slight jolt. Noah smiled at the people under his leadership—he, who had never led anything before, not even his own life—and said, “Here we go.”
That seemed inadequate, so he said, “We are off to the stars!”
That seemed dumb. Tony sneered. The journalist looked amused. Austin clutched his mother.
Noah said, “Your new life will be wonderful. Believe it.”
Kayla gave him a wobbly smile.
She could not imagine where she was.
Cool darkness, with the sky above her brightening every second. It had been so long since she’d seen a dawn sky, or any sky. Silver-gray, then pearl, and now the first flush of pink. The floor rocked gently. Then the last of the knock-out gas left her brain and she sat up. A kind of glorified barge, flat and wide with a single square rod jutting from the middle. The barge floated gently on New York Harbor. The sea was smooth as polished gray wood. In one direction rose the skyline of Manhattan; in the other, the Embassy. All around her lay her colleagues: Dr. Rafat, Harrison Rice and Ann Potter, lab techs Penny and Robbie, all the rest of the twenty-two people who’d still been aboard the Embassy. They wore their daily clothing. In her jeans and tee, Marianne shivered in a sudden breeze.
Nearby lay a pile of blankets. She took a yellow one and wrapped it around her shoulders. It felt warm and silky, although clearly not made of silk. Other people began to stir. Pink tinged the east.
Harrison came to her side. “Marianne?”
Automatically she said, because she’d been saying so many times each day, “I feel fine.” And then, “What the fuck?”
He said something just as pointless: “But we have two more weeks!”
“Oh my God!” someone cried, pointing, and Marianne looked up. The eastern horizon turned gold. Against it, a ship, dark and small, shot from the Embassy and climbed the sky. Higher and higher, while everyone on the barge shaded their eyes against the rising sun and watched it fly out of sight.
“They’re going,” someone said quietly.
They. The Denebs. Noah.
Before the tears that stung her eyes could fall, the Embassy vanished. One moment it was there, huge and solid and gray in the pre-dawn, and the next it was just gone. The water didn’t even ripple.
The metal rod in the center of the ship spoke. Marianne, along with everyone else, turned sharply. Shoulder-high, three feet on a 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 envelop your planet. We do not think it will harm you because—”
Someone in the crowd around the screen cried, “What?”
“—because 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 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.
