She grabbed the other radio, which was tuned to her silo. “Hank, do you read me?”

“Yes—?” She could hear him panting. “Hello?”

“Get everyone down to Mechanical. Everyone you can and as fast as you can. Now.”

“I feel like I should be going up,” Hank said. “Everyone is storming up.”

“No!” Juliette screamed into her radio. Walker startled and dropped the other radio’s microphone. “Listen to me, Hank. Everyone you can. Down here. Now!”

She cradled the radio in both hands, glanced around the room to see what else she should grab.

“Are we sealing off Mechanical?” Courtnee asked. “Like before?”

Courtnee must’ve been thinking about the steel plating welded across security during the holdout. The scars of those joints were still visible, the plating long gone.

“No time for that,” Juliette said. She didn’t add that it might all be pointless. The air could already be spoiled. No telling how long it took. A part of her mind wanted to focus on all that lay above her, all that she couldn’t save, the people and the things as well. Everything good and needed in the world that was now out of reach.

“Grab anything crucial and let’s go.” She looked to the two of them. “We need to go right now. Courtnee, get to the kids and get them back to their silo—”

“But you said … that mob—”

“I don’t care about them. Go. And take Walk with you. See that he gets to the dig. I’ll meet you there.”

“Where are you going?” Courtnee asked.

“To get as many others as I can.”

The hallways of Mechanical were strangely devoid of panic. Juliette ran through scenes of normalcy, of people walking to and from their shifts, trolleys of spare parts and heavy pumps, a shower of sparks from someone welding, a flickering flashlight and a passer-by tapping it with their fist. The radio had brought word to her ahead of time. No one else knew.

“Get to the dig,” she shouted to everyone she passed. “That’s an order. Now. Now. Go.”

There was a delayed response. Questions. Excuses. People explained where they were heading, that they were busy, that they didn’t have time right then.

Juliette saw Dawson’s wife, Raina, who would’ve been just coming off shift. Juliette grabbed her by the shoulders. Raina’s eyes widened, her body stiffened, to be handled like that.

“Get to the classroom,” Juliette told her. “Get your kids, get all the kids, and get them through the tunnel. Now.”

“What the hell’s going on?” someone asked. A few people jostled by in the narrow passageway. One of Juliette’s old hands from first shift was there. A crowd was forming.

“Get to the fucking dig,” Juliette shouted. “We’ve got to clear out. Grab everyone you can, your kids, anything you think you need. This is not a drill. Go. Go!”

She clapped her hands. Raina was the first to turn and run, pushing herself through the packed corridor. Those who knew her best leapt into action soon after, rounding up others. Juliette raced toward the stairwell, shouting as she did for everyone to get to the other silo. She vaulted over the security gates, the guard on duty looking up with a startled “Hey!” Behind her, she could hear someone else yelling for everyone to follow, to get moving. Ahead of her, the stairway itself trembled. She could hear welds singing and loose struts rattling. Over this, she could hear the sound of boots stomping her way.

Juliette stood at the bottom of the stairwell and peered up through that wide gap between the stairs and the stairwell’s concrete wall. Various landings jutted out overhead, wide bands of steel that became narrow ribbons higher up. The shaft receded into darkness. And then she saw the white clouds like smoke higher up. Maybe from the Mids.

She squeezed the radio.

“Hank?”

No response.

“Hank, come back.”

The stairway hummed with the harmonics of heavy but distant traffic. Juliette stepped closer and rested a hand on the rail. It vibrated, numbing her hand. The clanging of boots grew louder. Looking up, she could see hands sliding down the rail above her, could hear voices shouting encouragement and confusion.

A handful of people from the one-thirties spilled down the last turn and seemed confused about where to go next. They had the bewildered look of people who had never known that the stairway ended, that there was this floor of concrete below their homes. Juliette yelled at them to head inside. She turned and shouted into Mechanical for someone to show them the way, to let them through security. They stumbled past, most of them empty-handed, one or two with children clutched to their chests or towed behind, or with bundles cradled in their arms. They spoke of fire and smoke. A man shuffled down, holding a bloody nose. He insisted that they should be heading up, that they should all be heading up.

“You,” Juliette said, grabbing the man by the arm. She studied his face, the crimson dripping from his knuckles. “Where are you coming from? What happened?” She indicated his nose.

“I fell,” he said, uncovering his face to talk. “I was at work—”

“Okay. That’s fine. Follow the others.” She pointed. Her radio barked with a disembodied voice. Shouting. An unholy din. Juliette moved away from the stairs and covered one ear, pressed the radio to the other. It sounded vaguely like Peter. She waited until he was done.

“Can barely hear you!” she yelled. “What’s going on?”

She covered her ear again and strained for his words. “—getting through. To the outside. They’re getting out—”

Her back found the concrete of the stairwell. She slid down into a crouch. A few dozen people scampered down the stairs. Some stragglers in the yellow of Supply joined them, clutching a few things. Hank arrived, finally, directing traffic, shouting at those who seemed eager to turn back, to head in the other direction. A handful of people from Mechanical came out to help. Juliette concentrated on Peter’s voice.

“—can’t breathe,” he said. “Cloud coming in. I’m in the galley. People pouring up. Everyone. Acting crazy. Falling over. Everyone dead. The outside—”

He gasped and wheezed between every other word. The radio clicked off. Juliette screamed into the handset a few times, but she couldn’t raise him. Gazing up the stairwell, she saw the fog overhead. The smoke pouring out into the stairway seemed to thicken. It grew more and more dense as Juliette watched, horrified.

And then something dark punched through – a shadow amid the white. It grew. There was a scream, a terrible peal as it flew down and down, past the landings, on the other side of the stairwell, and then a thudding boom as a person slammed into the deck. The violence of the impact was felt in Juliette’s boots.

More screams. This time from those nearby, those dozens spilling down the stairwell, the few who had made it. They crawled over one another in a dash for Mechanical. And the white smoke, it descended down the stairwell like a hammer.

Juliette followed the others into Mechanical – she was the last one through. The arms on one of the security gates had been busted backward. A crowd surged over the gates while some hopped sideways through the gap. The guard who was meant to prevent this helped people down on the other side and directed them where to go.

Juliette threw herself over and hurried through the crowd toward the bunkroom where the kids had been put up. Someone was clattering around in the break room as she passed, hopefully looting needed things. Hopefully looting. The world had gone suddenly mad.

The bunkroom was empty. She assumed Courtnee had already gotten there. No one was getting out of Mechanical, anyway. And it was probably already too late. Juliette doubled back down the hall and headed for the winding stairs that penetrated the levels of Mechanical. She surged with a packed crowd down to the generator room and the site of the dig.

There were piles of tailings and chunks of concrete studded with rebar around the oil rig, which continued to bob its head up and down as if it knew the sad ways of the world, as if depressedly resigned to what was happening, as if saying: “Of course. Of course.”

More tailings and rubble from the dig formed piles inside the generator room, everything that hadn’t yet been shoveled down the shaft to mine six. There was a scattering of people, but not the crowds Juliette had hoped. The great crowds were likely dead. And then a fleeting thought, an urge to laugh and feel ridiculous, the idea that the smoke was nothing, that the airlock up top had held, that everything was okay and that her friends would soon rib her about this panic she had caused.

But this hope vanished as quickly as it came. Nothing could cut through the metallic fear on her tongue, the sound of Peter’s voice telling her that the airlock was wide open, that people were collapsing, Lukas telling her that Sims was dead.

She pushed through the crowd pouring into the tunnel and called out for the children. Then she spotted Courtnee and Walker. Walker was wide-eyed, his jaw sagging. Juliette saw the crowds through his eyes and realized the burden she had left Courtnee with, the challenge of dragging this recluse once again from his lair.

“Have you seen the kids?” she yelled over the crowd.

“They’re already through!” Courtnee yelled back. “With your father.”

Juliette squeezed her arm and hurried into the darkness. There were lights flashing ahead – the few who had battery-powered torches, those with miner’s hats on – but between these beams were wide swaths of pitch black. She jostled with the invisible others who materialized solidly out of shadow. Rocks clattered down from the piles of tailings to either side; dust and debris fell from the ceiling, eliciting shrieks and curses. The passage was narrow between the rows of rubble. The tunnel had been made for a handful of people to pass through, no more. Most of the massive hole bored through the earth had been left full of the scraps the digging had generated.

Where logjams formed, some people attempted to scamper up and along the tops of these piles. This just pushed heaps of dirt and rock down on those between, filling the tunnel with screams and curses. Juliette helped dig someone out and urged everyone to stay in the center, not to shove, even as someone practically climbed over her back.

There were others who tried to turn back, afraid and confused and distrusting of this dark run in a straight line. Juliette and others yelled for them to continue on. A nightmare formed of bumping into the support beams hastily erected in the center of the tunnel, of crawling on hands and knees over tall piles from partial cave-ins, of a baby crying at the top of its lungs somewhere. The adults did a better job of dampening their sobs, but Juliette passed by dozens crying. The journey felt interminable, as if they would crawl and stumble through that tunnel for the rest of time, until the poisonous air caught them from behind.

A jam of foot traffic formed ahead, people shoving at each others’ backs, and flashlight beams played over the steel wall of the digger. The end of the tunnel. The access door at the back of the machine was open. Juliette found Raph standing by the door with one of the flashlights, his pale face aglow in the darkness, eyes wide and white.

“Jules!”

She could barely hear him over the voices echoing back and forth in the dark shaft. She made her way to him, asked him who had already passed through.

“It’s too dark,” he said. “They can only get through one at a time. What the hell is going on? Why all the people? We thought you said—”

“Later,” she told him, hoping there would be a later. She doubted it. More likely, there would be piles of bodies at both ends of this silo. That would be the great difference between 17 and 18. Bodies at both ends. “The kids?” she asked, and as soon as she did, she wondered why with all the dead and dying she would concentrate on so few. The mother she never was, she suspected. The primal urge to look after her brood when far more than that was in peril.

“Yeah, quite a few kids came through.” He paused and shouted directions to a couple who didn’t want to enter the metal door at the back of this digger. Juliette could hardly blame them. They weren’t even from Mechanical. What did these people think was going on? Just following the panicked shoutings of others. Probably thought they were lost in the mines. It was a wild experience even for Juliette, who had scaled hills and seen the outside.

“What about Shirly?” Juliette asked.

He aimed his torch inside. “Saw her for sure. I think she’s in the digger. Directing traffic.”

She squeezed Raph’s arm, looked back at the writhing darkness of shadowy forms behind her. “Make sure you get through,” she told him, and his pale face nodded his consent.

Juliette squeezed into the queue and entered the back of the digger. Cries and shouts rattled within like children screaming into empty soup cans. Shirly was at the back of the power plant, directing the shuffling and shoving mass of people through a crack in the darkness so narrow that everyone had to turn sideways. The lights that’d been rigged up inside the digger to work the tailings were off, the backup generator idle, but Juliette could feel the residual heat from it having been run. She could hear the clicking of metal as it cooled. She wondered if Shirly had been operating the unit in order to move the machine and its power plant back toward Silo 18. She and Courtnee had been arguing over where the digger belonged.

“What the hell?” Shirly asked Juliette when she spotted her.

Juliette felt like bursting into tears. How to explain what she feared, that this was the end of everything they’d ever known? She shook her head and bit her lip. “We’re losing the silo,” she finally managed. “The outside’s getting in.”
