boards could drift away.
“Yes. I get it,” Rhys said. Then he added, “It’s not for me to tell you your business. But you know what hermit crabs do, don’t you?”
It took Dinah a few moments to access the memory. She had never been a beach kind of person. “They use the discarded shells of other crabs as shelter.”
“Not of other crabs, but of mollusks. But yes, you have it.”
Dinah thought about it for a moment, then turned to look at him. He seemed slightly less green and sweaty than before. “I think I see where you are going.”
“Better yet,” Rhys said, “consider the foraminifera.”
“What are they?”
“The biggest single-celled organisms in the world. They live beneath the Antarctic ice. And as they grow, they take grains of sand from their environment and glue them together to form hard outer skins.”
“Sort of like Ben Grimm?” she asked.
It was a throwaway reference to a comic book character, the armor-plated member of the Fantastic Four. She didn’t expect him to pick up on it. But he shot back: “To name another cosmic ray victim, yes. But without the alienation and self-pity.”
“I always wanted skin like the Thing.”
“It wouldn’t suit you nearly as well as the skin God gave you. But as a way for you to protect your robots from cosmic rays, while giving them the freedom to roam around—”
“I think I’m in love,” she said.
He clapped a bag over his mouth and threw up.
HOW DO YOU TELL THE WORLD THAT IT’S GOING TO DIE? DOOB WAS glad he didn’t have to say it. Instead he just stood behind the president of the United States. His job was to look serious—which wasn’t difficult—as part of a Mount Rushmore of eminent scientists lined up behind a semicircle of world leaders. He stared at the back of J.B.F.’s head as she explained it into a teleprompter. Bracketing her were the Chinese and the Indian presidents, saying the same things at the same time in Mandarin and Hindi. Fanning out into the wings were the prime ministers of Japan, the United Kingdom, France, and (acting as a sort of proxy for most of Latin America, as well as his own country) Spain; the chancellor of Germany; the presidents of Nigeria, Russia, and Egypt; the pope; prominent imams from the main branches of the Islamic faith; a rabbi; and a lama. The announcements were made simultaneously, so that as much of the human race as possible would hear the news at the same instant, and not have to await translations.
If the task had fallen to Dubois Jerome Xavier Harris, Ph.D., he would have said something like this: Look, everybody dies. Of the seven billion people now living on Earth, basically all will be dead a hundred years from now—most a lot sooner. No one wants to die, but most calmly accept that it’s going to happen.
A person who died two years from now in the Hard Rain would be no deader than someone who died seventeen years from now in a car crash.
The only thing that had changed now was that everyone knew the approximate time and manner of their death.
And knowing that, they could make preparations. Some of those were internal: making your peace with your God. Others had to do with passing on one’s legacy to the next generation.
And that was where things got interesting, because none of the traditional legacy-passing schemes was going to survive the Hard Rain. There was no point in drawing up a last will and testament, because all of your possessions were going to be destroyed along with you, and there would be no survivors to receive them.
The legacy was instead going to consist of whatever the people of the Cloud Ark did in the centuries and millennia to come. The Cloud Ark was the only thing that mattered.
They did it at Crater Lake, Oregon. The State Department had commandeered the rustic lodge perched high above the lake on the crater’s rim, flown in the dignitaries, crammed the nearby campgrounds and parking lots with security and media and logistics. At this very moment, marines out on the highway were turning back disappointed holidaymakers, telling them the park was closed, letting them know that they should turn on their radios and listen to the news if they really wanted to understand why. To put the disruption of their vacations into perspective.
The weather was clear, which meant it was cold. The lake down in the crater was the purest blue Doob had ever seen, the sky above it a lighter tint of the same color. He and all the others stood with their backs to it during the announcement. Some political genius on the president’s staff had figured out just how the imagery was supposed to work. The cameras were up on a scaffolding so that they could shoot downward, ensuring that the panorama of the crater, Wizard Island with its sparse covering of trees, and the snow-streaked mountain rim were all there in the high-definition backdrop of the shot. The message was there for anyone who wanted to read it. Between six and eight thousand years ago, an unimaginable catastrophe had befallen this place. The surviving humans had kept the story alive in legends of an apocalyptic struggle between the gods of the sky and of the underworld. Now, it was beautiful. The president and some of the other leaders were weaving that story into their announcements. Doob and the scientists around him—professors from great universities all over the world—couldn’t hear what was being said. The leaders were projecting their words outward into the world, and the sounds coming out of their mouths were swallowed up in the rushing of the wind over rocks and through trees. Doob, four meters behind the president, watched the wind mess with her hair. J.B.F.’s hair had been much commented on during the days before Zero, when such things had actually seemed important to commentators in the world of fashion and politics. It was dusky blond, streaked with silver. She wore it straight and shoulder-length. She was forty-two years old, which made her the youngest president of the United States, edging out J.F.K. by a year. She had flirted with politics during her student years at Berkeley but then opted for an M.B.A. and a stint with a high-powered business consultancy before taking a job at a clever but struggling Los Angeles tech firm. Under her leadership the company had turned its fortunes around to the point where it had been acquired by Google in a deal that had made her wealthy. She had married an actor turned producer, ten years older, whom she had met at a dinner party in Malibu. He already had dogs in various political fights, since a number of his films had been overtly political documentaries or thrillers with political overtones. Latino, with some family history of persecution under Castro, Roberto was something of a political chameleon, mixing libertarianism and populism in a way that intrigued both sides without repelling anyone save the most hard-core extremists. He got away with it because he was handsome, charming, and, as he freely admitted, not book-smart enough to puzzle out all the issues.
Having thus settled into a family life, and made a much-discussed decision to keep her maiden name, Julia Bliss Flaherty had swung her sights around to politics. She had narrowly lost a senatorial race in California. Visibly pregnant by the time Election Day arrived, she had soon given birth to a baby with Down syndrome and become a human Rorschach blot for all sorts of angst around amniocentesis and selective abortion. Making the rounds of talk shows to discuss those topics, she had drawn the eye of national political campaigns on both sides of the aisle. During the following presidential campaign, she had found herself in the unusual position of being on both parties’ vice presidential short lists. She was staunchly middle-of-the-road, with enough ambiguity in her politics to extend the Democrats’ reach rightward and the Republicans’ leftward. No one had expected her to end up in the Oval Office; that was never seriously expected, nowadays, of vice presidents. But the scandal that had brought down the president in only the tenth month of his inaugural year had elevated her to the presidency and made her hairstyle fair game for dissertation-length treatments in the press. Much of it was about those glints of silver. Were they natural, or artificial? If natural, why didn’t she get rid of them? The technology existed. If artificial, then wasn’t it really just a sneaky trick to make her look older, more serious? Either way, should a woman in today’s society need to make herself look matronly in order to be taken seriously?
Doob was pretty sure that no such articles would ever again be written after the announcement that J.B.F. was making today. And indeed he felt
