Overton brought his rifle back down to waist level, and joined Luke in surveying the skyline. He wasn’t a history buff, but he knew enough to know the man was right. He shook his head and began the journey back to the bunker.

“Where are you going, Sergeant?” Luke asked.

“I’m going to gather my men and supplies. We’re heading back to the Biosphere within the hour. You’re welcome to come with,” he said, disappearing down the stairs.

Luke looked like he had just been hit in the gut. He watched Sophie, who still stood at the edge of the roof, transfixed by the sporadic rays of blue shooting out of Colorado Springs. He studied her for a moment before making his way to the staircase. He had to stop Overton; he couldn’t let them leave. No one was going anywhere.

CHAPTER 20

FINLEY, Bouma, gear up. We’re heading out ASAP,” Overton shouted, the words echoing through the cave.

A pair of footsteps rang out from the metal stairs behind him, and moments later he felt the grip of a hand on his injured shoulder. He grimaced. “Hands off,” he growled.

“Sergeant Overton, you’re making a big mistake,” Luke said. “Your facility is more than likely already compromised. Besides, you’re all welcome to stay here. I have supplies, and my magnetic device will prevent them from ever finding us. We should wait out the invasion and reemerge when they leave,” he insisted. “We need each other. With your NTC training, and my resources, this could be the safest place on Earth.”

Overton pulled his bicep free from the man’s grip. “Reemerge to what? To a world without water? No, I’m not risking that. I’m leading my men back to the Biosphere, where the rest of our team is. I made a promise, and I’m not the type of man to go back on my word. You’re welcome to come with and bring your little magnet toy. ”

Luke laughed. “I don’t suppose I could change your mind?” He looked at Sophie and held her eye for a second. She walked over to Overton and stood shoulder to shoulder with the Marine.

“We have people back at the Biosphere. We’ve got to go back,” she said sternly.

“Very well,” Luke replied.

“Thanks for your hospitality,” Overton said. He finished packing his bag and turned to see Luke had vanished.

Fuck. Just what I needed.

“Men, keep an eye on him,” Overton said. “I don’t trust him. Something tells me he isn’t quite right in the head.”
