His phone rang. Held at arm’s length it was blurry, but some vestigial part of his brain could still recognize the smear of pixels as a snapshot of Bo, taken years ago. He swiped it on and answered it.
“We are being contacted by the Swarm,” Bo said.
“Are we really?” he answered. Suddenly he was awake. “What does J.B.F. want?”
“It’s not J.B.F. It’s someone named. .” Bo paused. “A-ida. Or something. Two dots on the i.”
Doob tried to place the name. Aïda. He had a vague memory of her from his early days on the Cloud Ark. An Italian girl. Young. Arkie, not GPop. Socially a little weird. Hyperacute in a way that could be exhausting.
“It’s pronounced ‘I-yeeda,’” he told Bo.
“Anyway, they send congratulations on the successful completion of our maneuver, and request a parley. Should I wake up Ivy?”
“I’ll be there in a minute,” Doob said. “Let her sleep.”
He hated to think this way, but the Swarmers well knew what time it was, and which shift Ivy slept on, and that she was sleeping now. Rousting her out of bed would send the wrong message, making the crew of Endurance seem overeager.
Which might have been an excess of caution — a J.B.F.-style exercise of byzantine thinking — he reflected, as he pushed himself up the middle of the Stack. This had become a dingy place, sort of yellowed and shiny with human exhalations, condensed on its ice-cold walls and never really scrubbed off. He was glad he couldn’t see it very well.
They knew so little about the Swarm. From the straggler arklets they’d picked up over the last three years, they knew that J.B.F. had moved swiftly to consolidate her power, exploiting the crisis of the first coronal mass ejection — which had killed something like 10 percent of the population — to set up her own version of martial law. From there the trains had run more or less on time, albeit with a steadily dwindling population, until about a year ago, when some Arkies had begun to rebel and the Swarm had divided into two Swarms, coexisting with each other — as they had little choice — but not talking.
The people of Endurance had paid surprisingly little attention to matters Swarm related, because, in the end, it didn’t really matter that much. The die had been cast on the day of the Break. Not so much on the level of politics as on physics. Those who had stayed behind on Izzy had committed themselves to following Doob’s plan, his life’s work: the Big Ride. You were either aboard Endurance, simultaneously trapped and protected by her mass, or you weren’t. If you were, there was no getting off. If you weren’t, you had to find a way to survive as part of the Swarm, which meant moving to a completely different orbit and following a plan that was incompatible, on an orbital mechanics level, with the Big Ride. Once those orbits had diverged, the only way to reconnect was by effecting a big delta vee. That meant spending a lot of water that you were never going to get back. Less water meant less shielding from coronal mass ejections, limited food production, and hobbled maneuvering when bad rocks came at you. Getting a whole Swarm to agree on that course of action was impossible, and might actually have been a bad idea, since Endurance couldn’t accommodate a lot of refugees. Her mission plan was predicated on her ability to absorb significant bolide strikes without taking serious damage. A bunch of naked arklets following in her wake would soon get beaten to death. So on a physics level alone, the Break had been irrevocable, even had the two groups badly wanted to get together.
But apparently what was left of the Swarm had been watching Endurance. Biding their time, waiting to see whether she would win through.
This Aïda person must understand Doob’s plan. She knew what was at stake now. If the remnants of the Swarm could rejoin Endurance in the next ten days, before she disappeared into the maelstrom of the debris cloud, they had a hope of reaching the comparative safety of Cleft. Otherwise they were condemned to circle Earth in some relatively clean and safe orbit as their population and their water supply dwindled.
Doob swam into the Hammerhead. Three other people were in here: Bo, Steve Lake, and Michael Park, a former Arkie, a gay Korean-Canadian from Vancouver who had found six different ways to make himself indispensable.
“Aïda Ferrari, according to our records,” Bo said, before he asked. “A leader of the anti-J.B.F. faction. Sounds like J.B.F. lost.”
Steve seemed busy. It was good to see him active. He had come down with some kind of long-running bowel complaint, an imbalance in the bacteria that lived in his gut. He had kept the dreadlocks, but they were now bigger than he was. He must weigh less than a hundred pounds. But his fingers still flew over the keys of his laptop.
Bo had already turned her attention back to the business of running the ship, but Michael explained, “Steve’s getting a video feed going. No one’s done it in years.”
He meant that no one had recently been doing it over the old-school S-band radios used for long-range communication between space vehicles. Of course, on the short-range mesh network that the Arkitects had set up to knit the Cloud Ark together, people did it all the time using Scape. But depending on where they were in their orbit, the remnants of the Swarm might be hundreds of thousands of kilometers away from Endurance, far out of mesh range, and so they had to use the same sort of pre-Internet technology that the Apollo astronauts had used to send television signals back from the moon.
Eventually Steve did get it going, and then they were treated to a full-face image, in blocky pixels, of a dark-eyed woman with a fine-featured head that had been buzz-cut a few weeks ago and little tended since.
Once Steve did him the favor of throwing it up on a big screen where he could actually see it, Doob saw the obvious signs of malnutrition that had been affecting everyone on Endurance. He was mildly surprised by that. They had tantalized themselves by imagining the Swarm as a cornucopia of agriculture. But maybe it was low on water. The woman’s gaze was downcast, which, as everyone understood, meant that she was focusing on the screen of a tablet below the camera. Once she understood that the link was up and running, she raised her chin and seemed to stare directly into the Hammerhead with a pair of huge dark eyes. The low quality of the video made these seem pitch black, with no distinction between iris and pupil, and starvation had given them a sort of hot gleam.
“Aïda,” the woman said, by way of self-introduction. “I see you, Dr. Harris.” She began to smile, offering a glimpse of bad teeth, then thought better of it. Her eyes changed direction momentarily to someone or something off-camera, then came back to them. She raised her tablet up closer to the camera so that she could look at the feed from Endurance. Her hand passed briefly in front of the lens and they caught a glimpse of dirty, ragged fingernails, the frayed and shiny cuff of a sleeve. Faint murmurs in the background suggested that other people were in the same arklet with her, off-camera. She was in zero gee, therefore, not part of a bolo. Her eyes were exploring the feed on her tablet, trying to make sense of what she was seeing. The Hammerhead had not existed at the time of the Break, so it was a new thing to her. “Steve Lake,” she muttered, as she recognized him.
“Bo,” Bo said.
“Michael,” Michael said.
“Who is in charge?” Aïda asked. “Is Ivy. .”
“Ivy’s still alive and she is still the commander as per CAC,” Doob said. “She’s off shift. We can wake her up if you need to speak to her urgently.”
“No. Not necessary,” Aïda said, recoiling slightly and narrowing the eyes just a bit. The distance between her and Endurance introduced a time lag in the video, which made conversation halting and awkward.
“How many do you have?” Doob asked.
“Eleven.”
Doob, accustomed to working professionally with extremely large numbers, couldn’t quite process one so small. Eleven. One plus ten.
A thought came to him. “Do you mean eleven arklets?” That would imply scores, maybe a hundred people.
Aïda looked amused. “Oh no, of arklets we have many more. We have twenty-six.”
“Ah. So what is it you have eleven of?”
“People,” Aïda said.
“Aïda,” Bo said, “just to be clear. So there is no misunderstanding. You are speaking for the entire Swarm. And you are saying that, of the entire Swarm, there are eleven survivors.”
“Yes. Plus one. .”
“One what?”
A look of amusement came over Aïda’s face. She broke eye contact. It almost seemed that she rolled her eyes a little. Doob was reminded, hardly for the first time, that the Arkies had been sent up as teenagers. “It is complicated. Let’s just say there is one more who might as well be dead.”
Those in the Hammerhead still could not quite process it. Something occurred to Michael: “We know that the Swarm broke up into two factions. One led by J.B.F. You were part of the opposing group?”
“Yes.” Aïda laughed. Again she reminded Doob of a teenager going through the pretense of talking to a clueless parent about something they would never understand.
Michael, a little wrong-footed, went on haltingly: “And so when you say that there are eleven. . plus one who is, I take it, in a bad way. . anyhow, are you referring just to the anti-J.B.F. faction?”
