About this book

Summary

Five days. Twelve cities. A pathogen engineered for total extinction. Deep in the Oregon wilderness, a secret laboratory holds the key to humanity's annihilation—and CDC epidemiologist Dr. James Reynolds has just learned that the mastermind behind it is someone he once trusted with his life. His former mentor has assembled a team of brilliant, broken scientists united by grief and a terrifying conviction. Now James must dismantle their plan from the inside, never knowing which allies might already belong to her.

Chapter 1: The Warning

The email arrived at 3:47 AM, slipping into James Reynolds' inbox like a whisper from the dead.

He wouldn't have seen it until morning if not for insomnia—the same persistent wakefulness that had plagued him since his divorce three years ago. He'd been staring at the ceiling of his Atlanta apartment, listening to the distant hum of traffic on Peachtree Street, when his phone buzzed on the nightstand.

James reached for it reflexively, expecting spam or perhaps a late-night query from one of his graduate students. Instead, he found a message from an address he didn't recognize: truthseeker_omega@protonmail.com.

The subject line read simply: "She's going to kill everyone."

He almost deleted it. His position as lead epidemiologist at the CDC made him a target for conspiracy theorists and doomsday prophets. Every week brought new warnings about government-engineered plagues or vaccine plots. He'd learned to ignore them.

But something made him open this one.

The message contained no greeting, no signature. Just two paragraphs of text and an attachment.

"Dr. Reynolds, you don't know me, but I know your work. More importantly, I know Dr. Sarah Chang's work. What she's building in Oregon will make every pandemic in human history look like a common cold. Genesis-7 is real. It's airborne. It's 100% lethal. And she plans to release it in twelve cities simultaneously within the next five days. I'm attaching coordinates and schematics. Please believe me. You're the only one who might be able to stop her."

James read the message twice, his heart rate climbing despite his skepticism. Sarah Chang. He hadn't heard that name spoken aloud in years, though he thought of her often. His mentor during his doctoral work at Johns Hopkins. The woman who'd taught him everything he knew about viral pathogenesis. The brilliant, passionate scientist who'd vanished from academic life after her husband was killed in the Tokyo subway attack.

That had been seven years ago. A lone actor with a weaponized strain of influenza had released it during rush hour, killing 847 people over the following weeks. Among them was David Chang, a visiting professor of economics who'd been in the wrong place at the wrong time.

Sarah had attended the memorial service in a black dress, her face carved from stone. She'd accepted condolences with mechanical grace, thanked everyone for coming, and then simply... disappeared. Resigned her position. Sold her house. Stopped answering emails and phone calls.

James had tried to reach her for months. He'd left voicemails that went unreturned, sent letters that came back undelivered. Eventually, he'd accepted that she wanted to grieve in private, and he'd respected that wish.

But this email suggested something far darker than grief.

He opened the attachment, a PDF file containing hand-drawn schematics of what appeared to be a laboratory facility. The coordinates placed it in rural Oregon, somewhere in the Cascade Range. There were notes scrawled in the margins, technical specifications that James recognized as biosafety protocols—but inverted, designed to contain something rather than protect against it.

The final page showed a molecular diagram labeled "Genesis-7." James studied it for a long moment, his trained eye picking apart the structure. It appeared to be a chimeric virus, combining elements of several respiratory pathogens with modifications he'd never seen before.

If this diagram was accurate—and that was a significant if—whoever had designed this pathogen was either a genius or a madman. Possibly both.

He should report this to his superiors. That was the protocol. Any credible threat of bioterrorism went straight up the chain of command, where people with security clearances and tactical training could assess and respond.

But James knew what would happen if he did that. The email would be logged, analyzed, and ultimately dismissed as another crank warning. The coordinates would be noted but not investigated—not without more concrete evidence. By the time anyone took it seriously, it might be too late.

And there was another reason he hesitated. If Sarah Chang was really behind this—if his mentor had somehow transformed from a healer into a destroyer—he needed to see it for himself. He needed to understand.

James sat up in bed and turned on the lamp. Sleep was no longer an option. He had a flight to book.

---

The CDC campus was quiet at 6 AM, the parking lot nearly empty as James pulled into his usual spot. He'd showered, dressed, and packed a bag on autopilot, his mind churning through possibilities and contingencies.

His office on the third floor of Building 18 was cluttered with the detritus of a decade's work: stacked journals, framed certificates, a whiteboard covered in equations he'd meant to erase weeks ago. He ignored all of it, heading straight for his computer.

For the next two hours, he researched. He pulled up everything he could find on Sarah Chang's post-disappearance activities, which amounted to almost nothing. A few conference papers with her name attached, all from the first year after David's death. A single interview in a scientific journal, where she'd discussed the future of pandemic preparedness with what now seemed like bitter irony.

Then silence. Complete and total silence.

He cross-referenced the coordinates from the email with satellite imagery. The location was remote, accessible only by a single unpaved road that wound through dense forest. There was a structure there—he could see it in the most recent images, a low building that might have been a hunting lodge or storage facility.

Or a laboratory.

James leaned back in his chair and rubbed his eyes. He was building a case on circumstantial evidence and anonymous accusations. Any rational person would dismiss this as paranoid fantasy.

But James had spent his career studying how diseases spread, how outbreaks began, how small oversights became catastrophic failures. He understood, perhaps better than most, how thin the line was between civilization and collapse.

And he knew Sarah Chang. He knew her brilliance, her intensity, her capacity for both great compassion and terrible focus. If anyone could engineer humanity's extinction, it was her.

He picked up his phone and dialed a number from memory.

"Marcus Webb," answered a gruff voice on the third ring.

"It's James Reynolds. I need a favor."

A pause. "It's six in the morning, James. On a Saturday."

"I know. I'm sorry. But this is important."

Marcus Webb was a former Army Ranger who now worked as a security consultant, mostly for pharmaceutical companies worried about industrial espionage. He and James had met five years ago during an outbreak investigation that had required armed escorts, and they'd stayed in touch.

"What kind of favor?" Marcus asked, his voice shifting from annoyed to curious.

"The kind where I need someone who knows how to handle themselves in a dangerous situation. And who won't ask too many questions."

"Those are usually the most interesting favors. Where and when?"

"Oregon. Today, if possible. I'll explain on the way."

Another pause, longer this time. "You know I trust you, James. But you're going to have to give me something. I can't walk into a situation blind."

James considered how much to reveal. "I have reason to believe a former colleague is developing a biological weapon. I need to confirm it before I can involve the authorities."

"Jesus." Marcus exhaled slowly. "And you can't just call the FBI?"

"Not without proof. And not without risking that she disappears before anyone can stop her."

"She?"

"Dr. Sarah Chang. You may have heard of her."

"The name sounds familiar. Wasn't she involved in some of the early COVID research?"

"Among other things. She's one of the most brilliant virologists in the world. Or she was, before she dropped off the grid."

Marcus was quiet for a moment. "Alright. I'm in. But if this goes sideways, you're buying drinks for a year."

"Deal. I'll send you the flight details."

James ended the call and began booking tickets. Portland was the closest major airport to the coordinates. From there, they'd need to rent a car and drive several hours into the mountains.

As he finalized the arrangements, his phone buzzed with a new message. Same anonymous address.

"You're making the right choice. But be careful. She's not alone. And they're all true believers."

James stared at the screen, feeling the weight of what he was about to do settle onto his shoulders. He was walking into the unknown, chasing shadows and whispers, betting everything on the word of someone he'd never met.

But if the alternative was doing nothing while Sarah Chang ended the world, it wasn't really a choice at all.
