After Korolyov, they encountered no one. The radios and TVs went dead as satellites were shot out; the pistes were empty; the Earth was on the other side of the sun. The landscape seemed as barren as before their arrival, except for the spreading patches of frost. They flew on as if they were the only people in the world, the sole survivors.

White noise buzzed in Nadia’s ear, something to do with the plane’s ventilators no doubt. She checked the ventilators, but they were okay. The others gave her chores to do, let her go on walks by herself before take-off, and after landing. They were stunned themselves by what they had found at Carr and Korolyov, and unable to bring much to the effort of cheering her up, which she found a relief. Ann and Simon were still worried about Peter. Yeli and Sax were worried about their food supplies, dropping all the time; the plane’s cabinets were nearly bare.

But Arkady was dead, and so none of that mattered. The revolt seemed to Nadia more a waste than ever, an unfocused spasm of rage, the ultimate cutting off one’s nose to spite one’s face. The whole world, wrecked! She told the others to send out a radio message on one of the general channels, announcing that Arkady was dead. Sasha agreed, and helped convince the others to do it. “It will help stop things more quickly,” Sasha said.

Sax shook his head. “Insurrections don’t have leaders,” he said. “Besides, no one is likely hear it.”

But a couple days later, it was clear some people had heard it. They received a microburst in response from Alex Zhalin. “Look, Sax, this isn’t the American Revolution, or the French or the Russian or the English. It’s all the revolutions at once, and everywhere! A whole world in revolt, with a land area equal to Earth’s, and only a few thousand people trying to stop it, and most of those still in space, where they have a good view but are very vulnerable. So if they manage to subdue a force in Syrtis, there is another in the Hellespontus. Imagine space-based forces trying to stop a revolution in Cambodia, but also in Alaska, Japan, Spain, Madagascar. How do you do it? You can’t. I only wish that Arkady Nikolayevich had lived to see it, he would have-”

The microburst ended abruptly. Perhaps a bad sign, perhaps not. But even Alex hadn’t been able to keep a note of discouragement out of his voice, when he talked about Arkady. It was impossible; Arkady had been so much more than a political leader-everybody’s brother, a natural force, the voice of one’s conscience. One’s innate sense of what was fair and just. One’s best friend.

Nadia stumped through her grief, helping to navigate their flights by night, sleeping as much as she could through the days. She lost weight. Her hair turned pure white, all the remaining gray and black hairs coming out in her brush. She found it hard to speak. It felt like her throat and guts had petrified. She was a stone, it was impossible to weep. She went about her business instead. No one they met had any food to spare, and they were running out themselves. They set a strict rationing schedule, dividing meals in half.

And on the thirty-second day of their journey from Lasswitz, after a journey of some ten thousand kilometers, they came to Cairo, up on the southern rim of Noctis Labyrinthus, just to the south of the southernmost strand of the fallen cable.

* * *

Cairo was under the de facto control of UNOMA, in that no one in the city had ever claimed otherwise, and like all the rest of the big tent cities it lay helpless under the orbiting lasers of UNOMA police ships, which had burned into orbit sometime in the last month. Also most of the inhabitants of Cairo at the beginning of the war had been Arab and Swiss, and in Cairo, at least, people of both nationalities seemed only to be trying to stay out of harm’s way.

Now, however, the six travelers were not the only refugees arriving; a flood of them had just come down Tharsis from the devastation in Sheffield and the rest of Pavonis; others were driving up from Marineris, through the maze of Noctis. The city was at quadruple capacity, with crowds living and sleeping in the streets and parks, the physical plant strained to the breaking point, and food and gases running out.

The six travelers were told this by an airstrip worker who was still stubbornly doing her job, although none of the strip shuttles were running any more. After guiding them into parking places among a great fleet of planes at one end of the strip, she told them to suit up and walk the kilometer to the city wall. It made Nadia unreasonably nervous to leave the two 17Ds behind and walk into a city; and she was not reassured once through the lock, when she saw that most people inside were wearing their walkers and carrying their helmets with them, ready for depressurization if it came.

They went to the city offices, and there found Frank and Maya, as well as Mary Dunkel and Spencer Jackson. They all greeted each other with relief, but there was no time for catching up on their various adventures; Frank was busy before a screen, talking to someone in orbit by the sound of it, and he shrugged off their hugs and kept talking, waving once later to acknowledge their appearance. Apparently he was hooked into a functioning communications system, or even more than one, because he stayed in front of the screen talking to one face or another for the next six hours straight, pausing only to sip water or make another call, not sparing another glance for his old compatriots. He seemed to be in a permanent fury, his jaw muscles bunching and unbunching rhythmically; other than that he was in his element, explaining and lecturing, wheedling and threatening, inquiring and then commenting impatiently on the answers he got. Wheeling and dealing in his old style, in other words, but with an angry, bitter, even frightened edge, as if he had walked off a cliff and was trying to argue his way back to ground.

When he finally clicked off, he leaned back in his seat and sighed histrionically, then rose stiffly from his seat and came over to greet them, putting a hand briefly on Nadia’s shoulder. Aside from that he was brusque with all of them, and completely uninterested in how they had managed to make it to Cairo. He only wanted to know whom they had met, and where, and how well these scattered parties were doing, and what they intended. Once or twice he went back to his screen and contacted these groups immediately upon being informed of their location, an ability that stunned the travelers, who had assumed that everyone was as cut off as they had been. “UNOMA links,” Frank explained, running a hand over his swarthy jaw. “They’re keeping some channels open for me.”

“Why?” Sax said.

“Because I’m trying to stop this. I’m trying for a cease-fire, then a general amnesty, then a reconstruction joined by all.”

“But under whose direction?”

“UNOMA’s, of course. And the national offices.”

“But UNOMA agrees only to the cease-fire?” Sax ventured. “While the rebels only agree to the general amnesty?”

Frank nodded curtly. “And neither like the reconstruction joined by all. But the current situation is so bad they may go for it. Four more aquifers have blown since the cable came down. They’re all equatorial, and some people are saying it’s cause and effect.”

Ann shook her head at this, and Frank looked pleased to see it. “They were broken open, I was pretty sure. They broke one at the mouth of Chasma Borealis, it’s pouring out onto the Borealis dunes.”

“The weight of the polar cap probably puts that one under a good bit of pressure,” Ann said.

“Do you know what happened to the Acheron group?” Sax asked Frank.

“No. They’ve disappeared. It might be like with Arkady, I’m afraid.” He glanced at Nadia, pursed his lips unhappily. “I should get back to work.”

“But what’s happening on Earth?” Ann demanded. “What does the UN have to say about all this?”
