“How can that be?” she asked. “We were heavy when the Pride let us go. I thought our problem was how to slow our descent.”

  “It was. Till our collision with whatever hit us. Based on where it struck, along the portside keel, I’d guess that it knocked off some of our static ballast—the stones lashed to our bottom. The same thing that happened to Pride during that awful thump quake. Other stones may have been dislodged or had just one of their lashings cut, leaving them to dangle below the starboard side, making us tilt like this. From these two examples, I’d say we’ve just learned a lesson today, about a really bad flaw in the whole way we’ve done sub design.”

  “So which is it? Are we rising?”

  Jonah nodded.

  “Slowly. It’s not too bad yet. And I suppose it’s possible we might resume our descent if we fill all the ballast tanks completely. Only there’s a problem.”

  “Isn’t there always?” Petri rolled her eyes, clearly exasperated.

  “Yeah.” He gestured toward where Xerish—by luck a carpenter—was hammering more bracing into place. Jonah lowered his voice. “If we drop back to the seafloor, that bearing may not hold against full-bottom pressure. It’s likely to start spewing again, probably faster.”

  “If it does, how long will we have?”

  Jonah frowned. “Hard to say. Air pressure would fight back, of course. Still, I’d say less than an hour. Maybe not that much. We would have to spot one of the canyon domes right away, steer right for it, and plop ourselves into dock as fast as possible, with everyone cranking like mad—”

  “—only using the propeller will put even more stress on the bearing,” Petri concluded with a thoughtful frown. “It might blow completely.”

  Jonah couldn’t prevent a brief smile. Brave enough to face facts … and a mechanical aptitude, as well? I could find this woman attractive.

  “Well, I’m sure we can work something out,” she added. “You haven’t let us down yet.”

  Not yet, he thought, and returned to work, feeling trapped by her confidence in him. And cornered by the laws of chemistry and physics—as well as he understood them with his rudimentary education, taken from ancient books that were already obsolete when the Founders first came to Venus, cowering away from alien invaders under a newborn ocean, while comets poured in with perfect regularity.

  Perfect for many lifetimes, but not forever. Not anymore. Even if we make it home, then go ahead with the Melvil Plan, and manage to find another bubble-filled canyon less affected by the rogue thumps, how long will that last?

  Wasn’t this whole project, colonizing the bottom of an alien sea with crude technology, always doomed from the start?

  In the middle compartment, Jonah opened his personal chest and took out some treasures—books and charts that he had personally copied under supervision by Scholar Wu, onto bundles of hand-scraped pinyon leaves. In one, he verified his recollection of Boyle’s Law and the dangers of changing air pressure on the human body. From another he got a formula that—he hoped—might predict how the leaky propeller-shaft bearing would behave if they descended the rest of the way.

  Meanwhile, Petri put a couple of the larger teen girls to work on a bilge pump, transferring water from the floor of the third compartment into some almost full ballast tanks. Over the next hour, Jonah kept glancing at the pressure gauge. The truck appeared to be leveling off again. Up and down. Up and down. This can’t be good for my old Bird.

  Leveled. Stable … for now. That meant the onus fell on him, with no excuse. To descend and risk the leak becoming a torrent, blasting those who worked the propeller crank … or else …

  Two hands laid pressure on his shoulders and squeezed inward, surrounding his neck, forcefully. Slim hands, kneading tense muscles and tendons. Jonah closed his eyes, not wanting to divulge what he had decided.

  “Some wedding day, huh?”

  Jonah nodded. No verbal response seemed needed. He felt married for years—and glad of the illusion. Evidently, Petri knew him now, as well.

  “I bet you’ve figured out what to do.”

  He nodded again.

  “And it won’t be fun, or offer good odds of success.”

  A headshake. Left, then right.

  Her hands dug in, wreaking a mixture of pleasure and pain, like life.

  “Then tell me, husband,” she commanded, then came around to bring their faces close. “Tell me what you’ll have us do. Which way do we go?”

  He exhaled a sigh. Then inhaled. And finally spoke one word.

  “Up.”

  7.

  TOWARD THE DEADLY SKY. TOWARD VENUSIAN HELL. IT HAD to be. No other choice was possible.

  “If we rise to the surface, I can try to repair the bearing from inside, without water gushing through. And if it requires outside work, then I can do that by putting on a helmet and coveralls. Perhaps they’ll keep out the poisons long enough.”

  Petri shuddered at the thought. “Let us hope that won’t be necessary.”

  “Yeah. Though while I’m there I could also fix the ballast straps holding some of the weight stones to our keel. I … just don’t see any other way.”

  Petri sat on a crate opposite Jonah, mulling it over.

  “Wasn’t upward motion what destroyed Leininger Colony and the Pride?”

  “Yes … but their ascent was uncontrolled. Rapid and chaotic. We’ll rise slowly, reducing cabin air pressure in pace with the decreased push of water outside. We have to go slow, anyway, or the gas that’s dissolved in our blood will boil and kill us. Slow and gentle. That’s the way.”

  She smiled. “You know all the right things to say to a virgin.”

  Jonah felt his face go red. He was relieved when Petri got serious again.

  “If we rise slowly, won’t there be another problem? Won’t we run out of breathable air?”

  He nodded. “Activity must be kept to a minimum. Recycle and shift stale air into bottles, exchanging with the good air they now contain. Also, I have a spark separator.”

  “You do? How did … aren’t they rare and expensive?”

  “I made this one myself. Well, Panalina showed me how to use pinyon crystals and electric current to split seawater into hydrogen and oxygen. We’ll put some passengers to work, taking turns at the spin generator.” And he warned her. “It’s a small unit. It may not produce enough.”

  “Well, no sense putting things off, then,” Petri said with a grandmother’s tone of decisiveness. “Give your orders, man.”

  The ascent was grueling. Adults and larger teens took turns at the pumps expelling enough ballast water for the sub to start rising at a good pace … then correcting when it seemed too quick. Jonah kept close track of gauges revealing compression both inside and beyond the shells. He also watched for symptoms of decompression sickness—another factor keeping things slow. All passengers not on shift were encouraged to sleep—difficult enough when the youngest children kept crying over the pain in their ears. Jonah taught them all how to yawn or pinch their noses to equalize pressure, though his explanations kept being punctuated by fits of sneezing.

  Above all, even while resting, they all had to breathe deep as their lungs gradually purged and expelled excess gas from their bloodstreams.

  Meanwhile, the forechamber resonated with a constant background whine as older kids took turns at the spark separator, turning its crank so that small amounts of seawater divided into component elements—one of them breathable. The device had to be working—a layer of salt gathered in the brine collector. Still, Jonah worried. Did I attach the poles right? Might I be filling the storage bottle with oxygen and letting hydrogen into the cabin? Filling the sub with an explosive mix that could put us out of our misery at any second?

  He wasn’t sure how to tell—none of his books said—though he recalled vaguely that hydrogen had no odor.

  After following him on his rounds, inspecting everything and repeating his explanations several times, Petri felt confident enough to insist, “You must rest now, Jon
ah. I will continue to monitor our rate of ascent and make minor adjustments. Right now, I want you to close your eyes.”

  When he tried to protest, she insisted, with a little more of the accented tone used by Laussane mothers. “We will need you far more in a while. You’ll require all your powers near the end. So lie down and recharge yourself. I promise to call if anything much changes.”

  Accepting her reasoning, he obeyed by curling up on a couple of grain sacks that Xerish brought forward to the control cabin. Jonah’s eyelids shut, gratefully. The brain, however, was another matter.

  How deep are we now?

  It prompted an even bigger question: how deep is the bottom of Cleopatra Canyon nowadays?

  According to lore, the first colonists used to care a lot about measuring the thickness of Venusian seas, back when some surface light used to penetrate all the way to the ocean floor. They would launch balloons attached to huge coils of string, in order to both judge depth and sample beyond the therm-o-cline barrier and even from the hot, deadly sky. Those practices died out—though Jonah had seen one of the giant capstan reels once, during a visit to Chown Dome, gathering dust and moldering in a swampy corner.

  The way Earth denizens viewed their planet’s hellish interior, that was how Cleo dwellers thought of the realm above. Though there had been exceptions. Rumors held that Melvil, that legendary rascal, upon returning from his discovery of Theodora Canyon, had demanded support to start exploring the great heights. Possibly even the barrier zone, where living things thronged and might be caught for food. Of course, he was quite mad—though boys still whispered about him in hushed tones.

  How many comets? Jonah found himself wondering. Only one book in Tairee spoke of the great Venus Terraforming Project that predated the Coss invasion. Mighty robots, as patient as gods, gathered iceballs at the farthest fringe of the solar system and sent them plummeting from that unimaginably distant realm to strike this planet—several each day, always at the same angle and position—both speeding the world’s rotation and drenching its long-parched basins. If each comet was several kilometers in diameter … how thick an ocean might spread across an entire globe, in twenty generations of grandmothers?

  For every one that struck, five others were aimed to skim close by, tearing through the dense, clotted atmosphere of Venus, dragging some of it away before plunging to the sun. The scale of such an enterprise was stunning, beyond belief. So much so that Jonah truly doubted he could be of the same species that did such things. Petri, maybe. She could be that smart. Not me.

  How were such a people ever conquered?

  The roil of his drifting mind moved onward to might-have-beens. If not for that misguided comet—striking six hours late to wreak havoc near the canyon colonies—Jonah and his bride would by now have settled into a small Laussane cottage, getting to know each other in more traditional ways. Despite, or perhaps because of the emergency, he actually felt far more the husband of a vividly real person than he would have in that other reality, where physical intimacy might have happened … Still, the lumpy grain sacks made part of him yearn for her in ways that—now—might never come to pass. That world would have been better … one where the pinyon vines waved their bright leaves gently overhead. Where he might show her tricks of climbing vines, then swing from branch to branch, carrying her in his arms while the wind of flying passage ruffled their hair—

  A twang sound vibrated the cabin, like some mighty cord coming apart. The sub throbbed and Jonah felt it roll a bit.

  His eyes opened and he realized I was asleep. Moreover, his head now rested on Petri’s lap. Her hand had been the breeze in his hair.

  Jonah sat up.

  “What was that?”

  “I do not know. There was a sharp sound. The ship hummed a bit, and now the floor no longer tilts.”

  “No longer—”

  Jumping up with a shout, he hurried over to the gauges, then cursed low and harsh.

  “What is it, Jonah?”

  “Quick—wake all the adults and get them to work pumping!”

  She wasted no time demanding answers. But as soon as crews were hard at work, Petri approached Jonah again at the control station, one eyebrow raised.

  “The remaining stone ballast,” he explained. “It must have been hanging by a thread, or a single lashing. Now it’s completely gone. The sub’s tilt is corrected, but we’re ascending too fast.”

  Petri glanced at two Sadoulites and two Laussanites who were laboring to refill the ballast tanks. “Is there anything else we can do to slow down?”

  Jonah shrugged. “I suppose we might unpack the leaky bearing and let more water into the aft compartment. But we’d have no control. The stream could explode in our faces. We might flood or lose the chamber. All told, I’d rather risk decompression sickness.”

  She nodded, agreeing silently.

  They took their own turn at the pumps, then supervised another crew until, at last, the tanks were full. Bird could get no heavier. Not without flooding the compartments themselves.

  “We have to lose internal pressure. That means venting air overboard,” he said, “in order to equalize.”

  “But we’ll need it to breathe!”

  “There’s no choice. With our tanks full of water, there’s no place to put extra air and still reduce pressure.”

  So, different pumps and valves, but more strenuous work. Meanwhile, Jonah kept peering at folks in the dim illumination of just two faint glow bulbs, watching for signs of the bends. Dizziness, muscle aches, and labored breathing? These could just be the result of hard labor. The book said to watch out also for joint pain, rashes, delirium, or sudden unconsciousness. He did know that the old dive tables were useless—based on Earth-type humanity. And we’ve changed. First because our scientist ancestors modified themselves and their offspring. But time, too, has altered what we are, even long after we lost those wizard powers. Each generation was an experiment.

  Has it made us less vulnerable to such things? Or more so?

  Someone tugged his arm. It wasn’t Petri, striving at her pump. Jonah looked down at one of the children, still wearing a stained and crumpled bridesmaid’s dress, who pulled shyly, urging Jonah to come follow. At first, he thought: it must be the sickness. She’s summoning me to help someone’s agony. But what can I do?

  Only it wasn’t toward the stern that she led him, but the forward-most part of the ship … to the view patch, where she pointed.

  “What is it?” Pressing close to the curved pane, Jonah tensed as he starkly envisioned some new cloud of debris … till he looked up and saw—

  —light. Vague at first. Only a child’s perfect vision would have noticed it so early. But soon it spread and brightened across the entire vault overhead.

  I thought we would pass through the therm-o-cline. He had expected a rough—perhaps even lethal—transition past that supposed barrier between upper and lower oceans. But it must have happened gently, while he slept.

  Jonah called someone to relieve Petri and brought her forth to see.

  “Go back and tell people to hold on tight,” Petri dispatched the little girl, then she turned to grab Jonah’s waist as he took the control straps. At this rate they appeared to be seconds away from entering Venusian hell.

  Surely it has changed, he thought, nursing a hope that had never been voiced, even in his mind. The ocean has burgeoned as life fills the seas …

  Already he spied signs of movement above. Flitting, flickering shapes—living versions of the crushed and dead specimens that sometimes fell to Tairee’s bottom realm, now undulating and darting about what looked like scattered patches of dense, dangling weed. He steered to avoid those.

  If the sea has changed, then might not the sky, the air, even the highlands?

  Charts of Venus, radar mapped by ancient Earthling space probes, revealed vast continents and basins, a topography labeled with names like Aphrodite Terra and Lakshmi Planum. Every single appellation was that of a female from histo
ry or literature or legend. Well, that seemed fair enough. But had it been a cruel joke to call the baked and bone-dry lowlands “seas”?

  Till humanity decided to make old dreams come true.

  What will we find?

  To his and Petri’s awestruck eyes, the dense crowd of life revealed glimpses—shapes like dragons, like fish, or those ancient blimps that once cruised the skies of ancient Earth. And something within Jonah allowed itself to hope.

  Assuming we survive decompression, might the fiery, sulfurous air now be breathable? Perhaps barely, as promised by the sagas? By now, could life have taken to high ground? Seeded in some clever centuries delay by those same pre-Coss designers?

  His mind pictured scenes from a few dog-eared storybooks, only enormously expanded and brightened. Vast, measureless jungles, drenched by rainstorms, echoing with the bellows of gigantic beasts. A realm so huge, so rich and densely forested that a branch of humanity might thrive, grow, prosper, and learn—regaining might and confidence—beneath that sheltering canopy, safe from invader eyes.

  That, once upon a time, had been the dream, though few imagined it might fully come to pass.

  Jonah tugged the tiller to avoid a looming patch of dangling vegetation. Then, ahead and above, the skyward shallows suddenly brightened, so fiercely that he and Petri had to shade their eyes, inhaling and exhaling heavy gasps. They both cried out as a great, slithering shape swerved barely out of the sub’s way. Then brilliance filled the cabin like a blast of molten fire.

  I was wrong to hope! It truly is hell!

  A roar of foamy separation … and for long instants Jonah felt free of all weight. He let go of the straps and clutched Petri tight, twisting to put his body between hers and the wall as their vessel flew over the sea, turned slightly, then dropped back down, striking the surface with a shuddering blow and towering splash.

  Lying crumpled below the viewing patch, they panted, as did everyone else aboard, groaning and groping themselves to check for injuries. For reassurance of life. And gradually the hellish brightness seemed to abate till Jonah realized, It is my eyes, adapting. They never saw daylight before.
