"I'm sorry. But it felt like the right time."
"It was. I was afraid of it at first. Listen, I know that I'm really a hundred years old, see? I know that all the memories are ready for me when I get to adulthood again. If I think about it, I can remember it all as plain as anything. But I haven't wanted to, and in a way, I still don't want to. The memories are suppressed when you opt for a second childhood instead of being transplanted into another full-grown body."
"I know."
"Do you? Oh, yeah. Intellectually. So did I, but I didn't understand what it meant. It's a nine- or ten-year holiday, not only from your work, but from yourself. When you get into your nineties, you might find that you need it."
She was quiet for a while, lying beside him without touching.
"What about the reintegration? Is that started?"
"I don't know. I've heard it's a little rough. I've been having dreams about something chasing me. That's probably my former self, right?"
"Could be. What did your older self do?"
He had to think for a moment, but there it was. He'd not thought of it for eight years.
"I was an economic strategist."
Before he knew it, he found himself launching into an explanation of offensive economic policy.
"Did you know that Pluto is in danger of being gutted by currency transfers from the Inner Planets? And you know why? The speed of light, that's why. Time lag. It's killing us. Since the time of the Invasion of Earth it's been humanity's idea—and a good one, I think—that we should stand together. Our whole cultural thrust in that time has been toward a total economic community. But it won't work at Pluto. Independence is in the cards."
She listened as he tried to explain things that only moments before he would have had trouble understanding himself. But it poured out of him like a breached dam, things like inflation multipliers, futures buying on the oxygen and hydrogen exchanges, phantom dollars and their manipulation by central banking interests, and the invisible drain.
"Invisible drain? What's that?"
"It's hard to explain, but it's tied up in the speed of light. It's an economic drain on Pluto that has nothing to do with real goods and services, or labor, or any of the other traditional forces. It has to do with the fact that any information we get from the Inner Planets is already at least nine hours old. In an economy with a stable currency—pegged to gold, for instance, like the classical economies on Earth—it wouldn't matter much, but it would still have an effect. Nine hours can make a difference in prices, in futures, in outlook on the markets. With a floating exchange medium, one where you need the hourly updates on your credit meter to know what your labor input will give you in terms of material output—your personal financial equation, in other words—and the inflation multiplier is something you simply must have if the equation is going to balance and you're not going to be wiped out, then time is really of the essence. We operate at a perpetual disadvantage on Pluto in relation to the Inner Planet money markets. For a long time it ran on the order of point three percent leakage due to outdated information. But the inflation multiplier has been accelerating over the years. Some of it's been absorbed by the fact that we've been moving closer to the I.P.; the time lag has been getting shorter as we move into summer. But it can't last. We'll reach the inner point of our orbit and the effects will really start to accelerate. Then it's war."
"War?" She seemed horrified, as well she might be.
"War, in the economic sense. It's a hostile act to renounce a trade agreement, even if it's bleeding you white. It hits every citizen of the Inner Planets in the pocketbook, and we can expect retaliation. We'd be introducing instability by pulling out of the Common Market."
"How bad will it be? Shooting?"
"Not likely. But devastating enough. A depression's no fun. And they'll be planning one for us."
"Isn't there any other course?"
"Someone suggested moving our entire government and all our corporate headquarters to the Inner Planets. It could happen, I guess. But who'd feel like it was ours? We'd be a colony, and that's a worse answer than independence, in the long run."
She was silent for a time, chewing it over. She nodded her head once; he could barely see the movement in the darkness.
"How long until the war?"
He shrugged. "I've been out of touch. I don't know how things have been going. But we can probably take it for another ten years or so. Then we'll have to get out. I'd stock up on real wealth if I were you. Canned goods, air, water, so forth. I don't think it'll get so bad that you'll need those things to stay alive by consuming them. But we may get to a semibarter situation where they'll be the only valuable things. Your credit meter'll laugh at you when you punch a purchase order, no matter how much work you've put into it."
The raft bumped. They had arrived at the edge of the world.
They moored the raft to one of the rocks on the wall that rose from the open ocean. They were five kilometers out of Rarotonga. They waited for some light as the sun began to rise, then started up the rock face.
It was rough: blasted out with explosives on this face of the dam. It went up at a thirty-degree angle for fifty meters, then was suddenly level and smooth as glass. The top of the dam at the edge of the world had been smoothed by cutting lasers into a vast table top, three hundred kilometers long and four kilometers wide. They left wet footprints on it as they began the long walk to the edge.
They soon lost any meaningful perspective on the thing. They lost sight of the sea-edge, and couldn't see the dropoff until they began to near it. By then, it was full light. Timed just right, they would reach the edge when the sun came up and they'd really have something to see.
A hundred meters from the edge when she could see over it a little, Lee began to unconsciously hang back. Piri didn't prod her. It was not something he could force someone to see. He'd reached this point with others, and had to turn back. Already, the fear of falling was building up. But she came on, to stand beside him at the very lip of the canyon.
Pacifica was being built and filled in three sections. Two were complete, but the third was still being hollowed out and was not yet filled with water except in the deepest trenches. The water was kept out of this section by the dam they were standing on. When it was completed, when all the underwater trenches and mountain ranges and guyots and slopes had been built to specifications, the bottom would be covered with sludge and ooze and the whole wedge-shaped section flooded. The water came from liquid hydrogen and oxygen on the surface, combined with the limitless electricity of fusion powerplants.
"We're doing what the Dutch did on Old Earth, but in reverse," Piri pointed out, but he got no reaction from Lee. She was staring, spellbound, down the sheer face of the dam to the apparently bottomless trench below. It was shrouded in mist, but seemed to fall off forever.
"It's eight kilometers deep," Piri told her. "It's not going to be a regular trench when it's finished. It's there to be filled up with the remains of this dam after the place has been flooded." He looked at her face, and didn't bother with more statistics. He let her experience it in her own way.
The only comparable vista on a human-inhabited planet was the Great Rift Valley on Mars. Neither of them had seen it, but it suffered in comparison to this because not all of it could be seen at once. Here, one could see from one side to the other, and from sea level to a distance equivalent to the deepest oceanic trenches on Earth. It simply fell away beneath them and went straight down to nothing. There was a rainbow beneath their feet. Off to the left was a huge waterfall that arced away from the wall in a solid stream. Tons of overflow water went through the wall, to twist, fragment, vaporize and blow away long before it reached the bottom of the trench.
Straight ahead of them and about ten kilometers away was the mountain that would become the Okinawa biome when the pit was filled. Only the tiny, blackened tip of the mountain would show above the water.
Lee stayed and looked at it as long as she could. I
t became easier the longer one stood there, and yet something about it drove her away. The scale was too big, there was no room for humans in that shattered world. Long before noon, they turned and started the long walk back to the raft.
She was silent as they boarded, and set sail for the return trip.
The winds were blowing fitfully, barely billowing the sail. It would be another hour before they blew very strongly. They were still in sight of the dam wall.
They sat on the raft, not looking at each other.
"Piri, thanks for bringing me here."
"You're welcome. You don't have to talk about it."
"All right. But there's something else I have to talk about. I... I don't know where to begin, really."
Piri stirred uneasily. The earlier discussion about economics had disturbed him. It was part of his past life, a part that he had not been ready to return to. He was full of confusion. Thoughts that had no place out here in the concrete world of wind and water were roiling through his brain. Someone was calling to him, someone he knew but didn't want to see right then.
"Yeah? What is it you want to talk about?"
"It's about—" she stopped, seemed to think it over. "Never mind. It's not time yet." She moved close and touched him. But he was not interested. He made it known in a few minutes, and she moved to the other side of the raft.
He lay back, essentially alone with his troubled thoughts. The wind gusted, then settled down. He saw a flying fish leap, almost passing over the raft. There was a piece of the sky falling through the air. It twisted and turned like a feather, a tiny speck of sky that was blue on one side and brown on the other. He could see the hole in the sky where it had been knocked loose.
It must be two or three kilometers away. No, wait, that wasn't right. The top of the sky was twenty kilometers up, and it looked like it was falling from the center. How far away were they from the center of Pacifica? A hundred kilometers?
A piece of the sky?
He got to his feet, nearly capsizing the raft.
"What's the matter?"
It was big. It looked large even from this far away. It was the dreamy tumbling motion that had deceived him.
"The sky is..." he choked on it, and almost laughed. But this was no time to feel silly about it. "The sky is falling, Lee." How long? He watched it, his mind full of numbers. Terminal velocity from that high up, assuming it was heavy enough to punch right through the atmosphere... over six hundred meters per second. Time to fall, seventy seconds. Thirty of those must already have gone by.
Lee was shading her eyes as she followed his gaze. She still thought it was a joke. The chunk of sky began to glow red as the atmosphere got thicker.
"Hey, it really is falling," she said. "Look at that."
"It's big. Maybe one or two kilometers across. It's going to make quite a splash, I'll bet."
They watched it descend. Soon it disappeared over the horizon, picking up speed. They waited, but the show seemed to be over. Why was he still uneasy?
"How many tons in a two-kilometer chunk of rock, I wonder?" Lee mused. She didn't look too happy, either. But they sat back down on the raft, still looking in the direction where the thing had sunk into the sea.
Then they were surrounded by flying fish, and the water looked crazy. The fish were panicked. As soon as they hit they leaped from the water again. Piri felt rather than saw something pass beneath them. And then, very gradually, a roar built up, a deep bass rumble that soon threatened to turn his bones to powder. It picked him up and shook him, and left him limp on his knees. He was stunned, unable to think clearly. His eyes were still fixed on the horizon, and he saw a white fan rising in the distance in silent majesty. It was the spray from the impact, and it was still going up.
"Look up there," Lee said, when she got her voice back. She seemed as confused as he. He looked where she pointed and saw a twisted line crawling across the blue sky. At first he thought it was the end of his life, because it appeared that the whole overhanging dome was fractured and about to fall in on them. But then he saw it was one of the tracks that the sun ran on, pulled free by the rock that had fallen, twisted into a snake of tortured metal.
"The dam!" he yelled. "The dam! We're too close to the dam!"
"What?"
"The bottom rises this close to the dam. The water here isn't that deep. There'll be a wave coming, Lee, a big wave. It'll pile up here."
"Piri, the shadows are moving."
"Huh?"
Surprise was piling on surprise too fast for him to cope with it. But she was right. The shadows were moving. But why?
Then he saw it. The sun was setting, but not by following the tracks that led to the concealed opening in the west. It was falling through the air, having been shaken loose by the rock.
Lee had figured it out, too.
"What is that thing?" she asked. "I mean, how big is it?"
"Not too big, I heard. Big enough, but not nearly the size of that chunk that fell. It's some kind of fusion generator. I don't know what'll happen when it hits the water."
They were paralyzed. They knew there was something they should do, but too many things were happening. There was not time to think it out.
"Dive!" Lee yelled. "Dive into the water!"
"What?"
"We have to dive and swim away from the dam, and down as far as we can go. The wave will pass over us, won't it?"
"I don't know."
"It's all we can do."
So they dived. Piri felt his gills come into action, then he was swimming down at an angle toward the dark-shrouded bottom. Lee was off to his left, swimming as hard as she could. And with no sunset, no warning, it got black as pitch. The sun had hit the water.
He had no idea how long he had been swimming when he suddenly felt himself pulled upward. Floating in the water, weightless, he was not well equipped to feel accelerations. But he did feel it, like a rapidly rising elevator. It was accompanied by pressure waves that threatened to burst his eardrums. He kicked and clawed his way downward, not even knowing if he was headed in the right direction. Then he was falling again.
He kept swimming, all alone in the dark. Another wave passed, lifted him, let him down again. A few minutes later, another one, seeming to come from the other direction. He was hopelessly confused. He suddenly felt he was swimming the wrong way. He stopped, not knowing what to do. Was he pointed in the right direction? He had no way to tell.
He stopped paddling and tried to orient himself. It was useless. He felt surges, and was sure he was being tumbled and buffeted.
Then his skin was tingling with the sensation of a million bubbles crawling over him. It gave him a handle on the situation. The bubbles would be going up, wouldn't they? And they were traveling over his body from belly to back. So down was that way.
But he didn't have time to make use of the information. He hit something hard with his hip, wrenched his back as his body tried to tumble over in the foam and water, then was sliding along a smooth surface. It felt like he was going very fast, and he knew where he was and where he was heading and there was nothing he could do about it. The tail of the wave had lifted him clear of the rocky slope of the dam and deposited him on the flat surface. It was now spending itself, sweeping him along to the edge of the world. He turned around, feeling the sliding surface beneath him with his hands, and tried to dig in. It was a nightmare; nothing he did had any effect. Then his head broke free into the air.
He was still sliding, but the huge hump of the wave had dissipated itself and was collapsing quietly into froth and puddles. It drained away with amazing speed. He was left there, alone, cheek pressed lovingly to the cold rock. The darkness was total.
He wasn't about to move. For all he knew, there was an eight-kilometer drop just behind his toes.
Maybe there would be another wave. If so, this one would crash down on him instead of lifting him like a cork in a tempest. It should kill him instantly. He refused to worry about that. All he cared about no
w was not slipping any further.
The stars had vanished. Power failure? Now they blinked on. He raised his head a little, in time to see a soft, diffused glow in the east. The moon was rising, and it was doing it at breakneck speed. He saw it rotate from a thin crescent configuration to bright fullness in under a minute. Someone was still in charge, and had decided to throw some light on the scene.
He stood, though his knees were weak. Tall fountains of spray far away to his right indicated where the sea was battering at the dam. He was about in the middle of the tabletop, far from either edge. The ocean was whipped up as if by thirty hurricanes, but he was safe from it at this distance unless there were another tsunami yet to come.
The moonlight turned the surface into a silver mirror, littered with flopping fish. He saw another figure get to her feet, and ran in that direction.
The helicopter located them by infrared detector. They had no way of telling how long it had been. The moon was hanging motionless in the center of the sky.
They got into the cabin, shivering.
The helicopter pilot was happy to have found them, but grieved over other lives lost. She said the toll stood at three dead, fifteen missing and presumed dead. Most of these had been working on the reefs. All the land surface of Pacifica had been scoured, but the loss of life had been minimal. Most had had time to get to an elevator and go below or to a helicopter and rise above the devastation.
From what they had been able to find out, heat expansion of the crust had moved farther down into the interior of the planet than had been expected. It was summer on the surface, something it was easy to forget down here. The engineers had been sure that the inner surface of the sky had been stabilized years ago, but a new fault had been opened by the slight temperature rise. She pointed up to where ships were hovering like fireflies next to the sky, playing searchlights on the site of the damage. No one knew yet if Pacifica would have to be abandoned for another twenty years while it stabilized.
