Captain Chen raised his son alone, raised him to be a good sailor, to love and serve the state, to never question orders, and to be the finest officer the Chinese navy had ever seen. The happiest day of his life was when Commander Chen Zhi Xiao received his first command, a brand-new Type 95 hunter-killer.

The kind that attacked you?

[Nods.] That was why Captain Chen would have done anything to avoid our fleet. That was why it was so important to know which sub had attacked us. To know is always better, no matter what the answer might be. He had already betrayed his oath, betrayed his homeland, and now to believe that that betrayal might have led him to murder his own son…

The next morning when Captain Chen did not appear for first watch, I went to his cabin to check on him. The lights were dim, I called his name. To my relief, he answered, but when he stepped into the light…his hair had lost its color, as white as prewar snow. His skin was sallow, his eyes sunken. He was truly an old man now, broken, withered. The monsters that rose from the dead, they are nothing compared to the ones we carry in our hearts.

From that day on, we ceased all contact with the outside world. We headed for the arctic ice, the farthest, darkest, most desolate void we could find. We tried to continue with our day-to-day life: maintaining the boat; growing food; schooling, raising, and comforting our children as best we could. With the captain’s spirit gone, so went the spirit of the Admiral Zheng’s crew. I was the only one who ever saw him during those days. I delivered his meals, collected his laundry, briefed him daily on the condition of the boat, then relayed his orders to the rest of the crew. It was routine, day in, day out.

Our monotony was only broken one day when sonar detected the approaching signature of another 95-class attack sub. We went to battle stations, and for the first time we saw Captain Chen leave his cabin. He took his place in the attack center, ordered a firing solution plotted, and tubes one and two loaded. Sonar reported that the enemy sub had not responded in kind. Captain Chen saw this as our advantage. There was no questioning in his mind this time. This enemy would die before it fired. Just before he gave the order, we detected a signal on the “gertrude,” the American term for an underwater telephone. It was Commander Chen, the captain’s son, proclaiming peaceful intentions and requesting that we stand down from GQ. He told us about the Three Gorges Dam, the source of all the “natural disaster” rumors we’d heard about in Manihi. He explained that our battle with the other 95 had been part of a civil war that the dam’s destruction had sparked. The sub that attacked us had been part of the loyalist forces. Commander Chen had sided with the rebels. His mission was to find us and escort us home. I thought the cheer was going to carry us right to the surface. As we broke through the ice and the two crews ran to each other under the arctic twilight, I thought, finally, we can go home, we can reclaim our country and drive out the living dead. Finally, it’s over.

But it wasn’t.

There was still one last duty to perform. The Politburo, those hated old men who had caused so much misery already, were still holed up in their leadership bunker in Xilinhot, still controlling at least half of our country’s dwindling ground forces. They would never surrender, everyone knew this; they would keep their mad hold on power, squandering what was left of our military. If the civil war dragged on any longer, the only beings left in China would be the living dead.

And you decided to end the fighting.

We were the only ones who could. Our land-based silos were overrun, our air force was grounded, our two other missile boats had been caught still tied to the piers, waiting for orders like good sailors as the dead swarmed through their hatches. Commander Chen informed us that we were the only nuclear asset left in the rebellion’s arsenal. Every second we delayed wasted a hundred more lives, a hundred more bullets that could be thrown against the undead.

So you fired on your homeland, in order to save it.

One last burden to shoulder. The captain must have noticed me shaking the moment before we launched. “My order,” he declared, “my responsibility.” The missile carried a single, massive, multi-megaton warhead. It was a prototype warhead, designed to penetrate the hardened surface of your NORAD facility in Cheyenne Mountain, Colorado. Ironically, the Politburo’s bunker had been designed to emulate Cheyenne Mountain in almost every detail. As we prepared to get under way, Commander Chen informed us that Xilinhot had taken a direct hit. As we slid beneath the surface, we heard that the loyalist forces had surrendered and reunified with the rebels to fight the real enemy.

Did you know they had begun instituting their own version of the South African Plan?

We heard the day we emerged from under the ice pack. That morning I came on watch and found Captain Chen already in the attack center. He was in his command chair, a cup of tea next to his hand. He looked so tired, silently watching the crew around him, smiling as a father smiles at the happiness of his children. I noticed his tea had grown cold and asked if he would like another cup. He looked up at me, still smiling, and shook his head slowly. “Very good, sir,” I said, and prepared to resume my station. He reached out and took my hand, looked up into, but did not recognize, my face. His whisper was so soft I could barely hear it.

What?

“Nice boy, Zhi Xiao, such a good boy.” He was still holding my hand when he closed his eyes forever.

SYDNEY, AUSTRALIA

[Clearwater Memorial is the newest hospital to be constructed in Australia and the largest one built since the end of the war. Terry Knox’s room is on the seventeenth floor, the “Presidential Suite.” His luxurious surroundings and expensive, almost unobtainable medication are the least his government can do for the first and, to date, only Australian commander of the International Space Station. In his words, “Not bad for the son of an Andamooka opal miner.”

His withered body seems to liven during our conversation. His face regains some of its color.]

I wish some of the stories they tell about us were true. Makes us sound all the more heroic. [Smiles.] Truth is, we weren’t “stranded,” not in terms of being suddenly or unexpectedly trapped up there. Nobody had a better view of what was happening than us. No one was surprised when the replacement crew from Baikonur failed to launch, or when Houston ordered us to pile into the X-38 1 for evacuation. I wish I could say that we violated orders or physically fought with one another over who should stay. What really happened was much more mundane and reasonable. I ordered the scientific team, and any other nonessential personnel, back to Earth, then gave the rest of the crew the choice to remain behind. With the X-38 reentry “lifeboat” gone, we would be technically stranded, but when you think of what was at stake then, I can’t imagine any of us wanting to leave.

The ISS is one of the greatest marvels of human engineering. We’re talking about an orbital platform so large it could be seen from Earth with the naked eye. It’d taken sixteen countries over ten years, a couple hundred space walks, and more money than anyone without job security would admit to finally complete her. What would it take to build another one, if another one could ever be built?

Even more important than the station was the incalculable, and equally irreplaceable, value of our planet’s satellite network. Back then there were over three thousand in orbit, and humanity depended on them for everything from communications to navigation, from surveillance to something even as mundane yet vital as regular and reliable weather prediction. This network was as important to the modern world as roads had been in ancient times, or rail lines during the industrial age. What would happen to humanity if these all-important links just started dropping out of the sky?

Our plan was never to save them all. That was unrealistic and unnecessary. All we had to do was concentrate on the systems most vital to the war effort, just a few dozen birds that had to remain aloft. That alone was worth the risk of staying.

Were you ever promised a rescue?

No, and we didn’t expect it. The issue wasn’t how we were going to get back to Earth, it was how we could manage to stay alive up there. Even with all our tanked O2 and emergency perchlorate candles, 2 even with our water recycling system 3 operating at peak capacity, we only had enough food for roughly twenty-seven months, and that was including the test animals in the lab modules. None of them were being used to test any kind of vaccines so their flesh was still edible. I can still hear their little shrieks, still see the spots of blood floating in micro gravity. Even up there, you couldn’t escape the blood. I tried to be scientific about it, calculating the nutritional value of every floating red globule I sucked out of the air. I kept insisting that it was all for the good of the mission and not my own ravenous hunger.

Tell me more about the mission. If you were trapped on the station, how did you manage to keep the satellites in orbit?

We used the “Jules Verne Three” ATV, 4 the last supply pod launched before French Guyana was overrun. It was originally designed as a one-way vehicle, to be filled with trash after depositing its cargo, then sent back to Earth to burn up in the atmosphere. 5 We modified it with manual flight controls and a pilot’s couch. I wish we could have fixed it with a proper viewport. Navigating by video wasn’t fun; neither was having to do my Extra Vehicular Activities, my space walks, in a reentry suit because there wasn’t room for a proper EVA kit.

Most of my excursions were to the ASTRO, 6 which was basically just a petrol station in space. Satellites, the military, surveillance type, sometimes have to change orbit in order to acquire new targets. They do that by firing their maneuvering thrusters and using up their small amount of hydrazine fuel. Before the war, the American military realized it was more cost-effective to have a refueling station already in orbit rather than sending up a lot of manned missions. That’s where ASTRO came in. We modified it to refuel some of the other satellites as well, the civilian models that need just the occasional top-off to boost back up from a decaying orbit. It was a marvelous machine: a real time-saver. We had a lot of technology like that. There was the “Canadarm,” the fifty-foot robotic inchworm that performed necessary maintenance tasks along the station’s outer skin. There was “Boba,” the VR-operated robonaut we fitted with a thruster pack so he could work both around the station and away from it on a satellite. We also had a little squadron of PSAs, 7 these free-floating robots, about the shape and size of a grapefruit. All of this wondrous technology was designed to make our jobs easier. I wish they hadn’t worked so well.

We had maybe an hour a day, maybe even two, where there was nothing to do. You could sleep, you could exercise, you could reread the same books, you could listen to Radio Free Earth or to the music we’d brought with us (over and over and over again). I don’t know how many times I listened to that Redgum song: “God help me, I was only nineteen.” It was my father’s favorite, reminded him of his time in Vietnam. I prayed that all that army training was helping to keep him and my mum alive now. I hadn’t heard anything from him, or anyone else in Oz since the government had relocated to Tasmania. I wanted to believe they were all right, but watching what was happening on Earth, as most of us did during our off-duty hours, made it almost impossible to have hope.

They say that during the cold war, American spy birds could read the copy of Pravda in a Soviet citizen’s hands. I’m not sure if that’s entirely true. I don’t know the tech specs of that generation of hardware. But I can tell you that these modern ones whose signals we pirated from their relay birds—these could show muscles tear and bones snap. You could read the lips of victims crying out for mercy, or the color of their eyes when they bulged with their last breath. You could see at what point red blood began to turn brown, and how it looked on gray London cement as opposed to white, Cape Cod sand.

We had no control over what the spy birds chose to observe. Their targets were determined by the U.S. military. We saw a lot of battles—Chongqing, Yonkers; we watched a company of Indian troops try to rescue civilians trapped in Ambedkar Stadium in Delhi, then become trapped themselves and retreat to Gandhi Park. I watched their commander form his men into a square, the kind the Limeys used in colonial days. It worked, at least for a little while. That was the only frustrating part about satellite surveillance; you could only watch, not listen. We didn’t know that the Indians were running out of ammunition, only that the Zed Heads were starting to close in. We saw a helo hover overhead and watched as the commander argued with his subordinates. We didn’t know it was General Raj-Singh, we didn’t even know who he was. Don’t listen to what the critics say about that man, about how he buggered off when things got too hot. We saw it all. He did try to put up a fight, and one of his blokes did smash him in the face with a rifle butt. He was out cold when they hauled him into that waiting chopper. It was a horrible feeling, seeing it all so close and yet unable to do anything.

We had our own observation gear, both the civilian research birds and the equipment right there on the station. The images they gave us weren’t half as powerful as the military versions, but they were still frighteningly clear. They gave us our first look at the mega swarms over central Asia and the American Great Plains. Those were truly massive, miles across, like the American buffalo must have once been.

We watched the evacuation of Japan and couldn’t help but marvel at the scale. Hundreds of ships, thousands of small boats. We lost count of how many helicopters buzzed back and forth from the rooftops to the armada, or how many jetliners made their final run north to Kamchatka.

We were the first ones to discover zombie holes, the pits that the undead dig when they’re going after burrowing animals. At first we thought they were just isolated incidents until we noticed that they were spreading all over the world; sometimes more than one would appear in close proximity to the next. There was a field in southern England—I guess there must have been a high concentration of rabbits—that was just riddled with holes, all different depths and sizes. Many of them had large, dark stains around them. Although we couldn’t zoom in close enough, we were pretty sure it was blood. For me that was the most terrifying example of our enemy’s drive. They displayed no conscious thought, just sheer biological instinct. I once watched a Zed Head go after something, probably a golden mole, in the Namib Desert. The mole had burrowed deep in the slope of a dune. As the ghoul tried to go after it, the sand kept pouring down and filling the hole. The ghoul didn’t stop, didn’t react in any way, it just kept going. I watched it for five days, the fuzzy image of this G digging, and digging, and digging, then suddenly one morning just stopping, getting up, and shuffling away as if nothing had happened. It must have lost the scent. Good on the mole.
