In Marc McKnight Time Travel Adventures by Kim Megahee, one man’s mission to safeguard the timeline becomes a decades-spanning struggle for his soul.

Captain Marc McKnight is trained to follow orders, not instincts — but when time travel makes both possible, he’s forced to choose between logic and love. In Time Limits, what should have been a simple one-week mission in 1985 unravels when human emotion enters the equation, creating an alternate timeline that haunts him. The Time Twisters sends McKnight against a cabal of renegade travelers who manipulate time to seize the presidency, transforming history into a chessboard of deceit. Time Revolution carries him to the year 2086, where a second American Revolution rages, and the line between patriot and terrorist has vanished. Then in Time Plague, McKnight’s final test arrives: a deadly virus from the future threatens humanity’s extinction — and only his most dangerous adversary holds the key to saving it. It’s a sweeping saga of love, loss, redemption, and the human need to make sense of time’s cruel design.

An Excerpt from Chapter 2 of TIME LIMITS by Kim Megahee

A few minutes later, they were on a path in a pine forest. A light breeze eased the heat of the Georgia sun and the pines whispered to them as they walked further into the woods.

McKnight glanced back in the direction they had come, then at the trail ahead. There was no one in sight. He pulled a form and a pen from his pocket and handed them to Tyler.

“First, the paperwork, Lieutenant. What I’m about to tell you is top secret and cannot be shared with unauthorized personnel, regardless of whether you accept the assignment. Is that understood?”

“Yes, sir.”

“Good. Sign the paper.”

Tyler signed and handed it back.

“Very good. Lieutenant, they've asked me to assemble a team to plan and execute missions using a new technology. The size of the team is fewer than ten, including two civilian scientists. I’d like you to be my exec for operations. I need a mission planner with leadership ability, and you’re it. The rest of the team’s still under construction, except for one scientist. We’ll be reporting to General Drake with oversight from Senator Lodge.”

“Working for the Dragon would be good. Oversight from Lodge? That’s not so good. He’s my Senator, but I didn’t vote for him. He’s a damned crocodile. I don’t trust him.”

“Lodge is the General’s problem. We’re the grunts. Our job is to execute.”

“So, what’ll we be doing?”

“The team is being called the HERO Project.”

Tyler rolled his eyes.

“Yeah, I know. Stay with me, Lieutenant. HERO stands for Historical Event Research Organization. In a nutshell, we’re going to be researching and validating historical events. Here, let’s take a load off.”

They sat on a wood bench alongside the running trail. McKnight looked across the path at a dogwood in full bloom and a bank of azaleas in unrestrained spring glory. Bumblebees hummed in and around the flowers.

“If you’re trying to sell me on how exciting the project will be, you’re failing miserably. Sounds like we’d be spending the next few years in the library and on the net, writing papers. Doesn’t sound like fun to me. Is there something I’m missing here?”

A thin smile formed on McKnight’s face. “Well, Lieutenant, I daresay we’ll be doing paperwork. I didn’t mention libraries or the net.”

Tyler scrunched up his face. “Then how? No library, no net. Where’s that leave us? Interviewing elderly witnesses?”

McKnight shook his head, waiting for Tyler to make the leap. Tyler sat on the bench, his elbows on his knees, his hands clasped together and his head down. After a moment, he looked at McKnight.

“You can’t be suggesting what I’m thinking.”

He’s getting there. “And what is that, Lieutenant?”

“Nope. I’m not going to say it. I must be missing something.” He paused. “All right. How do we witness an event in the past? We don’t have the technology to…. Wait, you mentioned a new technology, didn’t you?”

“I did.” McKnight allowed himself a little smile. One last hint. “You took physics at the Point, right?”

“What? Of course.”

“Um-hmm.”

Tyler stared at him. His eyes narrowed and darted around. He resumed the position with his elbows on his knees and his eyes on the ground.

“Who’s the scientist?” he said without looking up.

“Robert Astalos. He does research at MIT–”

“I'm familiar with him. I read a white paper he and his family wrote last year about interstellar propulsion. Son and grandson, I believe, all with the same name. Let’s see… Einstein related speeds close to the speed of light with time slowing down. Nobody has proved that wrong. And gravity is not a force, but a distortion of time-space. Everitt validated that.” Tyler sat up straight and looked McKnight in the eye. “Astalos invented time travel?”

Bingo. “Well, I’ll let him share the specifics with you, but that’s the bottom line. Interested, Lieutenant?”

“Are you kidding? Who wouldn’t be? Anything else you want to tell me? Do we have aliens in Area 51?”

McKnight laughed. “Not that I know of. Want the rest of the details, Lieutenant?”

“Yes, sir. You bet I do.”

“I thought you might. Here’s the short form. We’ll operate out of the DC area. Only a few people know about this. The charter for the HERO Team is strictly research. We’re forbidden to do anything that might affect history. There’s a mandatory risk/benefit analysis and research period required before traveling to make sure we cover the bases. No options, no exceptions, unless the President issues an Executive Order to bypass the process.

“The other civilian on the team will be another planner, your civilian counterpart. He or she hasn’t been picked yet. The General’s reserved the right to pick that person. You and I get no say,” McKnight said, holding up his hand to cut off any objection. “We need a shitload of testing before we can do any work. We don’t know enough about the technology yet. Questions?”

“Ha! Only a few hundred. This is supposed to be secret? Nobody outside the organization knows about it?”

“Well, for as long as that lasts. Congress is involved, right?”

“Yeah. I’m surprised the word isn't out already.”

McKnight shrugged. “The day is young. But yes, until we hear otherwise from the General, the project doesn’t exist and we’re working on special projects for Colonel Stewart.”

“Okay. Why do we need the civilian planner?” Tyler asked.

“The official word is to balance the team. I suspect it’s because Congress doesn’t trust the military. I assume it’ll be an egghead guy with serious credentials and no government ties. Drake wants someone with no agenda.”

“Got it. Do you have anyone else in mind for the team?”

“I do,” McKnight said. He pulled a folded piece of paper from his breast pocket and handed it to Tyler. “What do you think?”

“Lieutenant Mitch Wheeler. From North Georgia College, right? Good pick. Has a degree in physics if I remember correctly.”

“Yep. That one was easy. And his buddy Hatcher, too.”

“Yes, sir. Should be a good team.” Tyler handed the list back.

“Glad you approve.” McKnight checked the time on his phone. “I need to go catch a plane, Lieutenant. Transition your work ASAP and report to me in DC Monday week. Questions?”

“Yes, sir, but they can wait until next week.”

“Very good. I have two more instructions for you.” He stood and Tyler followed.

“What’s that, sir?”

McKnight smiled at his new executive officer. “Number one, don’t bring any preconceptions about time travel with you. Doctor Astalos says most of what the science fiction writers came up with was wrong.”

“And number two?”

“The other two Robert Astalos’s? The men that coauthored that paper?”

“Yes?”

“They aren’t his son and grandson. They’re all him. They call themselves Robert, Rob and Robby, but they’re all the same guy.”
