Crouched in the roadway was a single viral.

Peter had never seen one so motionless, at least not at night. It was facing the building, resting on its chiseled haunches, gazing at the building. While Peter watched, two more appeared out of the darkness, moving along the road and stopping to take up the same, vigilant posture, facing the firehouse. A pod of three.

“What’re they doing?” Peter whispered.

“Just standing there,” Hollis said. “They move around a bit but never come any closer.”

Peter pulled his face from the window. “You think they know we’re in here?”

“It’s tight but not that tight. They can smell the horse for sure.”

“Sara, go wake up Alicia,” Peter said. “Keep quiet-it’s best if everyone else stays asleep.”

Peter returned his face to the window. After a moment he asked, “How many did you say there were?”

“Three,” Hollis answered

“Well, there’s six now.”

Peter stood aside for Hollis to look.

“This is… bad,” Hollis said.

“What are the weak spots?” Alicia was beside them now. She freed the safety on her rifle and, making an effort to keep quiet, pulled the bolt. Then they heard it: a thump from above.

“They’re on the roof.”

Michael stumbled from the back room. He looked them over, frowning, his eyes blurry with sleep. “What’s going on?” he said, too loudly. Alicia touched a finger to her lips, then pointed urgently to the ceiling.

More sounds of impact came from overhead. In his gut Peter felt it, a soft bomb exploding. The virals were searching for a way in.

Something was scratching at the door.

A thump of flesh on metal, of bone on steel. It was as if the virals were testing it, Peter thought. Gauging its strength before they made a final push. He tightened the stock against his shoulder, ready to fire, just as Amy stepped into his line of vision. Later he would wonder if she’d been in the room all along, hiding in a corner, silently observing. She stepped to the barricade.

“Amy, get back-”

She knelt before the door, placing her palms against it. Her head was bowed, her brow touching the metal. Another thump from the far side, though softer this time, searching. Amy’s shoulders were trembling.

“What’s she doing?”

It was Sara who answered. “I think she’s… crying.”

No one moved. There were no more sounds coming from the far side of the door now. Finally Amy shifted off her knees and stood, facing them all. Her eyes were distant, unfocused; she seemed not to be seeing any of them.

Peter held up a hand. “Don’t wake her.”

While they watched in silence, Amy turned and walked, with the same otherworldly air, to the door to the bedroom, just as Mausami, the last sleeper, emerged. Amy pushed past her without appearing to notice her. The next thing they heard was the squeak of rusted springs as she lay down on her cot.

“What’s going on?” Mausami said. “Why is everybody looking at me like that?”

Peter went to check the window. He pressed his face against the slot. It was as he expected. Nothing was moving outside; the moonlit field was empty.

“I think they’re gone.”

Alicia frowned. “Why would they just leave like that?”

He felt strangely calm; the crisis, he knew, had passed. “Look for yourself.”

Alicia slung her rifle and pressed her eyes to the window, her neck straining as she tried to widen her field of vision through the opening.

“He’s right,” she reported. “There’s nothing out there.” She drew her face away and turned toward Peter, her eyes narrowed. “Like… pets?”

He shook his head, searching for the right word. “Like friends, I think.”

“Will somebody please tell me what’s going on?” Mausami said.

“I wish I knew,” said Peter.

They raised the barricade just after daybreak. All around they saw the creatures’ tracks in the dust. None of them had slept much, but even so, Peter felt a new energy coursing through him. He wondered what this was, and then he knew. They had survived their first night out in the Darklands.

The map spread out on a boulder, Hollis went over their route.

“After Twentynine Palms, it’s open desert through here, no real roads. The trick to finding the bunker is this range of mountains to the east. There are two distinct peaks at the south end, and a third behind them. When the third stands right in the middle of the two, turn due east, and you’re going the right way.”

“What if we don’t make it before dark?” he asked.

“We could hole up in Twentynine if we had to. There are a few structures still standing. But as I remember it they’re just hulks, nothing like the fire station.”

Peter glanced toward Amy, who was standing with the others. She was still wearing the brimmed cap from the supply room; Sara had also given her a man’s long-sleeved shirt to wear, frayed at the sleeves and collar, and a pair of desert glasses they’d found in the firehouse. Her black hair was pushed away from her face, a nimbus of dark tangles flapping under the brim of the cap.

“Do you really think she did it?” Hollis said. “Sent them away.”

Peter turned back toward his friend. He thought of the magazine in the bathroom, the two stark words on its cover.

“Truthfully, Hollis? I don’t know.”

“Well, we better hope she did. After Kelso, it’s open country clear to the Nevada line.” He drew his blade and wiped it on the hem of his jersey. When he resumed speaking his voice was quiet, confidential. “Before I left, you know, I heard people talking, saying things about her. The Girl from Nowhere, the last Walker. People were saying she was a sign.”

“Of what?”

Hollis frowned. “The end, Peter. The end of the Colony, the end of the war. The human race, or what’s left of it. I’m not saying they were right. It was probably just more of Sam and Milo’s bullshit.”

Sara stepped toward them. The swelling on her face had eased overnight; the worst of the bruising had faded to a greenish purple.

“We should let Maus ride,” she said.

“Is she okay?” Peter asked.

“A little dehydrated. In her condition, she has to keep her fluids up. I don’t think she should be walking in the heat. I’m worried about Amy, too.”

“What’s wrong with her?”

She shrugged. “The sun. I don’t think she’s used to it. She’s got a bad burn already. The glasses and shirt will help, but she can stay covered only so long in this heat.” She cocked her head and looked at Hollis. “So what’s this Michael tells me about a vehicle?”

They marched.

The mountains fell away behind them; by half-day, they were deep in open desert. The roadway was little more than suggestion, but they could still follow its course, tracing the bulge it made in the hardpan, through a landscape of scattered boulders and strange, stunted trees, beneath a boiling sun and a limitless sky bleached of all color. The breeze hadn’t so much died as collapsed; the air was so motionless it seemed to hum, the heat vibrating around them like an insect’s wings. Everything in the landscape looked both close and far away, the sense of perspective distorted by the immeasurable horizon. How easy it would be, Peter thought, to get turned around in such a place, to wander aimlessly until darkness fell. Past the town of Mojave Junction-no town at all, just a few empty foundations and a name on the map-they crested a small rise to discover a long line of abandoned vehicles, two abreast, facing the direction they had come. Most were passenger cars but there were some trucks as well, their rusted, sand-scoured chassis sunk in the drifting sand. It felt as if they’d stumbled on an open grave, a grave of machines. Many of the roofs had been peeled away, the doors torn off their hinges. The interiors looked melted; if there had once been bodies inside, they were long gone, scattered to the desert winds. Here and there in the undifferentiated debris, Peter detected a recognizable item of human scale: a pair of eyeglasses, an open suitcase, a child’s plastic doll. They passed in silence, not daring to speak. Peter counted over a thousand vehicles before they ended in a final plume of wreckage, the indifferent desert sands resuming.
