I found a balcony on a tower that looked out through the transparent canopy over the clouds. The cloudscape was just as magnificent as it had been the previous day; towering and slowly changing. The light was a rich golden color, and the Sun, masked by a skein of feathery clouds like a tracery of lace, was surrounded by a bronze halo. From the angle of the Sun it was early afternoon, but there would be no sunset that day; the great winds circling the planet would not blow the city into the night side of Venus for another day.
Of the eleven thousand other cities, I could detect no trace—looking outward, there was no indication that we were not alone in the vast cloudscape that stretched to infinity. But then, I thought, if the cities were scattered randomly, there would be little chance one would be nearby at any given time. Venus was a small planet, as planets go, but large enough to swallow ten thousand cities—or even a hundred times that—without any visible crowding of the skies.
I wished I knew what Leah thought of it.
I missed Leah. For all that she sometimes didn’t seem to even notice I was there . . . our sojourn on Mars, brief as it had been . . . we had shared the same cubby. Perhaps that meant nothing to her. But it had been the very center of my life.
I thought of her body, lithe and golden-skinned. Where was she? What was she doing?
The park was a platform overgrown with cymbidian orchids, braced in the air by the great cables that transected the dome from the stanchion trusswork. This seemed a common architecture here, where even the ground beneath was suspended from the buoyancy of the air dome. I bounced my weight back and forth, testing the resonant frequency, and felt the platform move infinitesimally under me. Children here must be taught from an early age not to do that; a deliberate effort could build up destructive oscillation. I stopped bouncing, and let the motion damp.
When I returned near the middle of the day, neither Truman nor Epiphany were there, and Truman’s other wife, a woman named Triolet, met me. She was perhaps in her sixties, with dark skin and deep gray eyes. She had been introduced to me the previous day, but in the confusion of meeting numerous people in what seemed to be a large extended family, I had not had a chance to really talk to her yet. There were always a number of people around the Singh household, and I was confused as to how, or even if, they were related to my hosts. Now, talking to her, I realized that she, in fact, was the one who had control of the Singh household finances.
The Singh family were farmers, I discovered. Or farm managers. The flora in Hypatia was decorative or served to keep the air in the dome refreshed, but the real agriculture was in separate domes, floating at an altitude that was optimized for plant growth and had no inhabitants. Automated equipment did the work of sowing and irrigation and harvest. Truman and Epiphany Singh were operational engineers, making those decisions that required a human input, watching that the robots kept on track and were doing the right things at the right times.
And there was a message waiting for me, inviting me in the evening to attend a dinner with His Excellency, Carlos Fernando Delacroix Ortega de la Jolla y Nordwald-Gruenbaum.
Triolet helped me with my wardrobe, along with Epiphany, who had returned by the time I was ready to prepare. They both told me emphatically that my serviceable but well-worn jumpsuit was not appropriate attire. The gown Triolet selected was far gaudier than anything I would have chosen for myself, an electric shade of indigo accented with a wide midnight black sash. “Trust us, it will be suitable,” Epiphany told me. Despite its bulk, it was as light as a breath of air.
“All clothes here are light,” Epiphany told me. “Spider’s silk.”
“Ah, I see,” I said. “Synthetic spider silk. Strong and light; very practical.”
“Synthetic?” Epiphany asked, and giggled. “No, not synthetic. It’s real.”
“The silk is actually woven by spiders?”
“No, the whole garment is.” At my puzzled look, she said, “Teams of spiders. They work together.”
“Spiders.”
“Well, they’re natural weavers, you know. And easy to transport.”
I arrived at the banquet hall at the appointed time and found that the plasma-arc blue gown that Epiphany had selected for me was the most conservative dress there. There were perhaps thirty people present, but Leah was clearly the center. She seemed happy with the attention, more animated than I’d recalled seeing her before.
“They’re treating you well?” I asked, when I’d finally made it through the crowd to her.
“Oh, indeed.”
I discovered I had nothing to say. I waited for her to ask about me, but she didn’t. “Where have they given you to stay?”
“A habitat next section over,” she said. “Sector Carbon. It’s amazing—I’ve never seen so many birds.”
“That’s the sector I’m in,” I said, “but they didn’t tell me where you were.”
“Really? That’s odd.” She tapped up a map of the residential sector on a screen built into the diamond tabletop, and a three-dimensional image appeared to float inside the table. She rotated it and highlighted her habitat, and I realized that she was indeed adjacent, in a large habitat that was almost directly next to the complex I was staying in. “It’s a pretty amazing place. But mostly I’ve been here in the upcity. Have you talked to Carli much yet? He’s a very clever kid. Interested in everything—botany, physics, even engineering.”
“Really?” I said. “I don’t think they’ll let me into the upcity.”
“You’re kidding; I’m sure they’ll let you in. Hey—” she called over one of the guards. “Say, is there any reason Tinkerman can’t come up to the centrum?”
“No, madam, if you want it, of course not.”
“Great. See, no problem.”
And then the waiters directed me to my place at the far end of the table.
The table was a thick slab of diamond, the faceted edges collecting and refracting rainbows of color. The top was as smooth and slippery as a sheet of ice. Concealed inside were small computer screens so that any of the diners who wished could call up graphics or data as needed during a conversation. The table was both art and engineering, practical and beautiful at the same time.
Carlos Fernando sat at the end of the table. He seemed awkward and out of place in a chair slightly too large for him. Leah sat at his right, and an older woman—perhaps his mother?—on his left. He was bouncing around in his chair, alternating between playing with the computer system in his table and sneaking glances over at Leah when he thought she wasn’t paying attention to him. If she looked in his direction, he would go still for a moment, and then his eyes would quickly dart away and he went back to staring at the graphics screen in front of him and fidgeting.
The server brought a silver tray to Carlos Fernando. On it was something the size of a fist, hidden under a canopy of red silk. Carlos Fernando looked up, accepted it with a nod, and removed the cloth. There was a moment of silence as people looked over, curious. I strained to see it.
It was a sparkling egg.
The egg was cunningly wrought of diamond fibers of many colors, braided into intricate lacework resembling entwined Celtic knots. The twelve-year-old satrap of Venus picked it up and ran one finger over it, delicately, barely brushing the surface, feeling the corrugations and relief of the surface.
He held it for a moment, as if not quite sure what he should do with it, and then his hand darted over and put the egg on the plate in front of Leah. She looked up, puzzled.
“This is for you,” he said.
The faintest hint of surprise passed through the other diners, almost subvocal, too soft to be heard.
A moment later the servers set an egg in front of each of us. Our eggs, although decorated with an intricate filigree of finely painted lines of gold and pale verdigris, were ordinary eggs—goose eggs, perhaps.
Carlos Fernando was fidgeting in his chair, half grinning, half biting his lip, looking down, looking around, looking everywhere except at the egg or at Le
ah.
“What am I to do with this?” Leah asked.
“Why,” he said, “perhaps you should open it up and eat it.”
Leah picked up the diamond-laced egg and examined it, turned it over and rubbed one finger across the surface. Then, having found what she was looking for, she held it in two fingers and twisted. The diamond eggshell opened, and inside it was a second egg, an ordinary one.
The kid smiled again and looked down at the egg in front of him. He picked up his spoon and cracked the shell, then spooned out the interior.
At this signal, the others cracked their own eggs and began to eat. After a moment, Leah laid the decorative shell to one side and did the same. I watched her for a moment, and then cracked my own egg.
It was, of course, excellent.
Later, when I was back with the Singh family, I was still puzzled. There had been some secret significance there that everybody else had seen, but I had missed. Mr. Singh was sitting with his older wife, Triolet, talking about accounts.
“I must ask a question,” I said.
Truman Singh turned to me. “Ask,” he said, “and I shall answer.”
“Is there any particular significance,” I said, “to an egg?”
“An egg?” Singh seemed puzzled. “Much significance, I would say. In the old days, the days of the asteroid miners, an egg was a symbol of luxury. Ducks were brought into the bigger habitats, and their eggs were, for some miners, the only food they would ever eat that was not a form of algae or soybean.”
“A symbol of luxury,” I said, musing. “I see. But I still don’t understand it.” I thought for a moment, and then asked, “Is there any significance to a gift of an egg?”
“Well, no,” he said, slowly, “not exactly. An egg? Nothing, in and of itself.”
His wife Triolet asked, “You are sure it’s just an egg? Nothing else?”
“A very elaborate egg.”
“Hmmm,” she said, with a speculative look in her eye. “Not, maybe, an egg, a book, and a rock?”
That startled me a little. “A book and a rock?” The Bruno book—the very first thing Carlos Fernando had done on meeting Leah was to give her a book. But a rock? I hadn’t see anything like that. “Why that?”
“Ah,” she said. “I suppose you wouldn’t know. I don’t believe that our customs here in the sky cities are well known out there in the outer reaches.”
Her mention of the outer reaches—Saturn and the Beyond—confused me for a moment, until I realized that, viewed from Venus, perhaps even Earth and the built worlds of the orbital clouds would be considered “outer.”
“Here,” she continued, “as in most of the ten thousand cities, an egg, a book, and a rock is a special gift. The egg is symbolic of life, you see; a book symbolic of knowledge; and a rock is the basis of all wealth, the minerals from the asteroid belt that built our society and bought our freedom.”
“Yes? And all three together?”
“They are the traditional gesture of the beginning of courtship,” she said.
“I still don’t understand.”
“If a young man gives a woman an egg, a book, and a rock,” Truman said, “I should say this is his official sign that he is interested in courting her. If she accepts them, then she accepts his courtship.”
“What? That’s it, just like that, they’re married?”
“No, no, no,” he said. “It only means that she accepts the courtship—that she takes him seriously and, when it comes, she will listen to his proposal. Often a woman may have rocks and eggs from many young men. She doesn’t have to accept, only take him seriously.”
“Oh,” I said.
But it still made no sense. How old was Carlos Fernando, twenty Venus years? What was that, twelve Earth years or so? He was far too young to be proposing.
“No one can terraform Venus,” Carlos Fernando said.
Carlos Fernando had been uninterested in having me join in Leah’s discussion, but Leah, oblivious to her host’s displeasure (or perhaps simply not caring), had insisted that if he wanted to talk about terraforming, I should be there.
It was one room of Carlos Fernando’s extensive palaces, a rounded room, an enormous cavernous space that had numerous alcoves. I’d found them sitting in one of the alcoves, an indentation that was cozy but still open. The ubiquitous female guards were still there, but they were at the distant ends of the room, within command if Carlos Fernando chose to shout, but far enough to give them the illusion of privacy.
The furniture they were sitting on was odd. The chairs seemed sculpted of sapphire smoke, yet were solid to the touch. I picked one up and discovered that it weighed almost nothing at all. “Diamond aerogel,” Carlos Fernando said. “Do you like it?”
“It’s amazing,” I said. I had never before seen so much made out of diamond. And yet it made sense here, I thought; with carbon dioxide an inexhaustible resource surrounding the floating cities, it was logical that the floating cities would make as much as they could out of carbon. But still, I didn’t know you could make an aerogel of diamond. “How do you make it?”
“A new process we’ve developed,” Carlos Fernando said. “You don’t mind if I don’t go into the details. It’s actually an adaptation of an old idea, something that was invented back on Earth decades ago, called a molecular still.”
When Carlos Fernando mentioned the molecular still, I thought I saw a sharp flicker of attention from Leah. This was a subject she knew something about, I thought. But instead of following up, she went back to his earlier comment on terraforming.
“You keep asking questions about the ecology of Mars,” she said. “Why so many detailed questions about Martian ecopoiesis? You say you’re not interested in terraforming, but are you really? You aren’t thinking of the old idea of using photosynthetic algae in the atmosphere to reduce the carbon dioxide, are you? Surely you know that that can’t work.”
“Of course.” Carlos Fernando waved the question away. “Theoretical,” he said. “Nobody could terraform Venus, I know, I know.”
His pronouncement would have been more dignified if his voice had finished changing, but as it was, it wavered between squeaking an octave up and then going back down again, ruining the effect. “We simply have too much atmosphere,” he said. “Down at the surface, the pressure is over ninety bars—even if the carbon dioxide of the atmosphere could be converted to oxygen, the surface atmosphere would still be seventy times higher than the Earth’s atmospheric pressure.”
“I realize that,” Leah said. “We’re not actually ignorant, you know. So high a pressure of oxygen would be deadly—you’d burst into flames.”
“And the leftover carbon,” he said, smiling. “Hundreds of tons per square meter.”
“So what are you thinking?” she asked.
But in response, he only smiled. “Okay, I can’t terraform Venus,” he said. “So tell me more about Mars.”
I could see that there was something that he was keeping back. Carlos Fernando had some idea that he wasn’t telling.
But Leah did not press him, and instead took the invitation to tell him about her studies of the ecology on Mars, as it had been transformed long ago by the vanished engineers of the long-gone Freehold Toynbee colony. The Toynbee’s engineers had designed life to thicken the atmosphere of Mars, to increase the greenhouse effect, to melt the frozen oceans of Mars.
“But it’s not working,” Leah concluded. “The anaerobic life is being out-competed by the photosynthetic oxygen-producers. It’s pulling too much carbon dioxide out of the atmosphere.”
“But what about the Gaia effect? Doesn’t it compensate?”
“No,” Leah said. “I found no trace of a Lovelock self-aware planet. Either that’s a myth, or else the ecology on Mars is just too young to stabilize.”
“Of course on Venus, we would have no problem with photosynthesis removing carbon dioxide.”
“I thought you weren’t interested in terraforming Venus,” I said.
Carlos Fernando waved my objection away. “A hypothetical case, of course,” he said. “A thought exercise.” He turned to Leah. “Tomorrow,” he said, “would you like to go kayaking?”
“Sure,” she said.
Kayaking, on Venus, did not involve water.
Carlos Fernando instructed Leah, and Epiphany helped me.
The “kayak” was a ten-meter long gas envelope, a transparent cylinder of plastic curved into an ogive at both ends, with a tiny bubble at the bottom where the kayaker sat. One end of the kayak held a huge, gossamer-bladed propeller that turned lazily as the kayaker pedaled, while the kayaker rowed with flimsy wings, transparent and iridescent like the wings of a dragonfly.
The wings, I discovered, had complicated linkages; each one could be pulled, twisted, and lifted, allowing each wing to separately beat, rotate, and camber.
“Keep up a steady motion with the propeller,” Epiphany told me. “You’ll lose all your maneuverability if you let yourself float to a stop. You can scull with the wings to put on a burst of speed if you need to. Once you’re comfortable, use the wings to rise up or swoop down, and to maneuver. You’ll have fun.”
We were in a launching bay, a balcony protruding from the side of the city. Four of the human-powered dirigibles that they called kayaks were docked against the blister, the bulge of the cockpits neatly inserted into docking rings so that the pilots could enter the dirigible without exposure to the outside atmosphere. Looking out across the cloudscape, I could see dozens of kayaks dancing around the city like transparent squid with stubby wings, playing tag with each other and racing across the sky. So small and transparent compared to the magnificent clouds, they had been invisible until I’d known how to look.
“What about altitude?” I asked.
“You’re about neutrally buoyant,” she said. “As long as you have airspeed, you can use the wings to make fine adjustments up or down.”
“What happens if I get too low?”
“You can’t get too low. The envelope has a reservoir of methanol; as you get lower, the temperature rises and your reservoir releases vapor, so the envelope inflates. If you gain too much altitude, vapor condenses out. So you’ll find you’re regulated to stay pretty close to the altitude you’re set for, which right now is,” she checked a meter, “fifty-two kilometers above local ground level. We’re blowing west at a hundred meters per second, so local ground level will change as the terrain below varies; check your meters for altimetry.”
