On her feet, she dusted off the dirt. “You must do this a lot.”

Drenched in sweat, he shrugged. “You get used to it. Too bad we couldn’t have done paintball today. I prefer that to the archery.”

“Me too.” Um . . . not really.

He turned and continued jogging down the trail. More participants passed her.

Mackenzie would hike the rest of the way. She was done running the course like everyone else. What about people who couldn’t participate for health reasons, or refused?

“On your left.”

Mackenzie slowed and turned to watch her sister—on the opposing red team—jogging toward her.

“I’m surprised to see you pulling up the rear of your team,” Mackenzie said.

“You’re last too. So whichever one of us is faster is going to win for our team.”

Nora passed her.

Mackenzie would walk the rest of the way, so she wouldn’t be catching up to Nora. She wasn’t accustomed to this kind of daily activity, though she had been at one time. She gasped for breath but emerged from the trees in time to see the red team cheering Nora on when she hit the target with her last Nerf arrow, then ran past the stone markers.

At least this was over.

And oddly, the blue team, who had lost because of her, cheered her on, then clapped her damp back when she practically dragged her feet—one foot in front of the other, that’s all she had to do—over the invisible line. Everyone was pumped, except for her. She could see the smiles and the camaraderie. No one was in pain.

Except Mackenzie.

Everyone else seemed exhilarated by the challenge. Dad had been right. Team building helped coworkers get to know each other even better over time. But she hadn’t learned anything that could help her discover who inside the company had helped the cybercriminal get into the system.

“Let’s end this day right!” someone shouted. “The zip line is ready to go.”

Another round of cheers.

Still catching her breath, Mackenzie frowned and watched as all the crazy fitness and outdoor enthusiasts cheered and walked in the same direction. She had only imagined she was an outdoor enthusiast.

The outdoor activities and fresh air brought new perspectives. She needed to look deeper into what she thought she could be missing. But first, she had to zip-line across a canyon with the Grayback River flowing along the bottom.

She hobbled forward to stand at the end of the line and glanced behind her. Maybe she could follow the trail back to the facility. Then again, she didn’t want to draw attention. Did they do a head count on the other side to make sure they weren’t missing anyone? She stared at the setup again.

Two men who wore T-shirts with a zip-line company emblem—Cross-Country Zip—assisted individuals into the harness. Oh, Lord . . .
