“Oh yeah,” the former soldier replied through a grunt as he stood up. “That would’ve been a lot of fun imagining them all burning to death when the flares struck.”

That killed the mood instantly. Mark felt his own face fall as the words made him think of his parents and Madison. Though he’d never know for sure what had happened to them, his mind was super talented at imagining the absolute worst.

Alec must have noticed. “Oh hell, I’m sorry.” He reached out and squeezed Mark’s shoulder. “Boy, I’m telling you right here and now, with all the sincerity an old buzzard like me can muster, that I’m sorry for what I just said. I don’t envy the losses you felt that day. Not one iota. Work was my family, and it wasn’t the same, I know it.”

Mark had never heard the man say anything like what’d just come out of his mouth. “It’s okay. Really. Thanks.” He paused, then added, “Grandpa.”

Alec nodded, then moved back to the wheel, spun it until there was a loud click. He swung the door open, and it clanged as it struck the wall.

The other side revealed nothing but darkness, though a rumbling hum like the sound of distant machinery grew louder.

“What is that?” Mark whispered. “It almost sounds like there’s a factory or something down here.” He aimed the workpad’s glow through the open doorway, revealing a long hallway that disappeared into darkness.

“Generator, I’m sure,” Alec responded.

“I guess they couldn’t live down here without at least a little electricity. How else would this thing work?” He held the device out in front of him.

“Exactly. We’ve been living in the wild or in the settlements so long. It brings back memories.”

“Bergs, generators… you think they have a ton of fuel stored here or are they bringing it in from somewhere else?”

Alec thought a second. “Well, it’s been a year, and it takes a heap to keep those Bergs afloat. My guess is they’re bringing it in.”

“We keep going?” Mark asked, though the answer was obvious.

“Yep.”

Mark stepped into the hallway first and waited for Alec to join him. “What do we do when someone sees us?” He was whispering, but his voice sounded loud in the confined quarters. “We could use a weapon or two about now.”

“Tell me about it. Look, we don’t have much choice here. And we don’t have a whole lot to lose. Let’s just keep moving and take it as it comes.”

They started off down the hallway when something clanged behind them, followed by squeals and grinding gears. Mark didn’t have to look to know that the landing pad-presumably with a Berg perched on top-had begun to sink into the ground.

Alec acted much calmer than Mark felt. He had to lean in to be heard over the racket. “Let’s wait to see which chamber it goes into and then we’ll hide in the other. We better not get caught in this hallway.”

“Okay,” Mark said, his heart thumping, his nerves on edge. He turned off the workpad; they didn’t need it with the light spilling in from outside.

They went back through the door and pulled it shut, then crouched in the shadows of the walkway as the huge Berg descended. Luckily the cockpit was on the other side, so there was little chance of them being seen. Once it had sunk all the way down, there were more clangs and squeals and the ship started moving on tracks into the chamber to the right. Alec and Mark ran to the opposite chamber and hid in the very back, disappearing into the gloom.

The wait was agonizing, but eventually the Berg found its home. When it stopped moving, the giant landing pad began to move upward again, slowly but surely. Whoever had flown the ship had already disembarked, because Mark could faintly hear voices over the noises, then the sound of the round door being opened.

“Come on,” Alec whispered into his ear. “Let’s follow them.”

They slipped out of the chamber and slinked along the walkway. The Berg passengers had left the door of the exit ajar, and Alec crouched next to it, leaning in to listen. He took a peek. Seemingly satisfied that they were in the clear, he gave Mark a stiff nod and slipped into the hallway once again. Mark followed just as the landing pad above him started to rotate, the bushes and earth and small trees heading back toward the sky.

Voices echoed down the passage ahead of them, but they were too distorted to understand. Alec took the workpad from Mark and slipped it inside his backpack. Then he grabbed Mark’s arm and started pulling him forward, walking close to the wall, his eyes narrowed. Soon everything would be plunged back into darkness.

They crept down the hallway, step by careful step. Whoever had shown up had decided to stop and talk, because their voices became clearer as Mark and Alec continued their pursuit. It sounded like there were only two of them. Alec finally stopped as well, and suddenly Mark could hear every word.

“-just north of here,” a woman was saying. “Burned out like a brick oven. I bet it’s got something to do with those people they caught last night. We’ll know soon enough.”

A man responded. “We better. Like things weren’t bad enough without losing our other Berg. Those jacks in Alaska couldn’t care less about us. Now that everything’s gone weird, I bet we don’t even hear from them again.”

“No doubt,” the woman said. “Can you say expendable?”

“Yeah, but that wasn’t supposed to be us. It’s not our fault the virus is mutating.”

The landing pad clanged behind them, presumably done with its rotation. All was dark. The new arrivals started walking away, their footsteps heavy, as if they wore boots. One of them clicked on a flashlight, the glow from its beam bobbing up ahead. Alec grabbed Mark again and they followed, keeping a safe distance.

The two strangers didn’t speak again until they reached a door. Mark heard the squeak of the hinges as it opened. Then the man said something as they stepped into a room Mark couldn’t see.

“They’ve already got a name for it, by the way. They’re calling it the Flare.”

The door slammed shut.

CHAPTER 32

They hadn’t heard much from the pair, but Mark didn’t like the sound of it. “The Flare. He said they’ve started calling it the Flare. The virus.”

“Yeah.” Alec lit up the workpad again. The glow revealed his face-the face of a man who looked as if he’d never smiled in his life. All sags and creases. “That can’t be good. If something has a nickname, that means it’s big and being talked about. Not good at all.”

“We need to find out what happened. Those people dancing around the fire got attacked way before us. At least their settlement did. Maybe they were some kind of test subjects?”

“Then we’ve got two objectives, kid: One, find Lana, Trina and that cute little whippersnapper. Two, figure out what’s going on around here.”

Mark couldn’t have agreed more. “So let’s get moving.”

Alec turned off the workpad, casting the hallway into darkness. “Just run your hand along the wall,” he whispered. “Try not to step on me.”

They started making their way down the passage. Mark kept his footsteps light and his breathing shallow, trying to stay silent. The humming of distant machinery had grown louder, and the wall vibrated as his fingers traced an invisible line along its cool surface. They reached a spot where the slightest outline of rectangular light marked the door through which the two strangers from the Berg had gone. Alec hesitated right before it, then hurried past on his tiptoes-the least soldierly thing Mark had ever seen him do.

Mark decided to be a little braver. He stopped in front of it and leaned in, pressing his ear against the door.

“Not smart,” Alec called out in a harsh whisper.

Mark didn’t respond, concentrating on what he could hear. Muffled words, impossible to make out. But the discussion sounded a little heated.
