Her Deadliest Mistake

“Ms. Tatiana. You must come in immediately—there’s been an emergency!”

The line went dead before she could even formulate a question.

Tatiana tucked the device back into her designer purse, ’Driver, reroute,” she commanded, her voice cutting through the quiet luxury sedan.

“Take me here.”

She slid a handwritten slip of paper through the partition, an address that didn’t exist on any public map.

A stern but soft-spoken gravel replied from the front,” Yes, ma’am.”

Tatiana leaned back, her mind already dissecting the tremor she had heard in the representative’s voice.

Panic of that magnitude wasn’t just a breach of protocol; it was a symptom of a total collapse.

They arrived at the industrial outskirts in under ten minutes. “Drop me off in the back, and ensure we weren’t followed,” Tatiana ordered, her tone surgical and sharp.

“Stay by your phone.”

The driver gave a single, disciplined nod, understanding that in this world, silence was the only way to stay alive.

Moments later, she stepped out into the warm air, her heels clicking against the pavement like a predatory countdown. “This better not be a waste of my time,” she whispered to the shadows.

She bypassed the main entrance for the private elevator, her fingers flying over the twenty-digit biometric keypad.

The elevators took her to the sub-levels where the organization’s secrets were kept under lock and key.

When the doors slid open, a tall, slender man in a black suit practically lunged toward her.

“Ma’am, let me get you up to speed,” he stammered, his tie loosened and his forehead gleaming with sweat.

“Since you were away, there’s been a little chaos—”

Tatiana stopped mid-stride, the temperature in the hallway seemingly dropping ten degrees.

“Little?”

The man swallowed hard, his Adam’s apple bobbing as he struggled to maintain his composure.

“Yes, ma’am… one of our high-profile cases has been targeted, and people are coming for them.”

Tatiana’s cheeks flushed a dangerous shade of crimson. “I was only gone for five days,” she hissed, her voice a low, lethal register.

“How could this happen?”

The man couldn’t meet her gaze, staring instead at the polished floor while his words stumbled over one another.

“I understand, Ms. Tatiana, but no one saw this coming.”

She glared at him, silently calculating exactly how many seconds it would take to rid her world of his incompetence. “Before I go in there,” she said, her voice dropping to a whisper that felt like a blade against his throat.

“Which high-profile case are we talking about?”

Beads of sweat broke out on the man’s face. “The Montagues, ma’am.”

The name hit her like a physical blow, widening her eyes and momentarily stealing the air from her lungs.

The name didn’t just worry her; it crippled her sense of order.

She adjusted her jacket, smoothing her mask of indifference back into place before entering the room,

Inside, the silence was heavy enough to be cut with a knife. She took her seat at the head of the table, and the atmosphere shifted from tense to suffocating.

Across from her sat Kyle, the youngest brother, his eyes darting toward the shadows. Next to him was Kaitlyn, the oldest sister, radiating a scent of ancient power and frozen fury. Beside Kyle sat Kameron, the middle brother and the family’s strategist.

These were the Montagues—the most powerful dynasty in the city, beings who had shaped the shadows for centuries. The fact that they had to come to this organization for help told Tatiana that the situation was officially catastrophic.

“We have a problem,” Kaitlyn snapped, slamming a manila folder onto the desk with the force of a gunshot.

Tatiana reached out to slide the folder toward her. Kameron’s hand shot out, his fingers cold against the paper. “That’s not how to greet someone we need help from, big sister,” Kameron gritted out.

Kaitlyn whirled on him, her eyes flashing a terrifying shade of amber and yellow. “You do not get to correct me!” she screamed. “We’re in this mess because of our young, dumb sibling!”

CRACK.

Tatiana slammed her palms down on the desk, the building’s foundation groaning as if an earthquake had hit. “You will not treat this meeting like a circus!” Tatiana growled, her voice vibrating through the floorboards.

“Why are you here?”

“We had an agreement; I don’t need to be seen with this family.”

“Sorry for our rude behavior, Ms. Tatiana, but we truly need you; Kyle said, his voice trembling like a leaf.

“What is it?”

I—” Kyle started, but Kaitlyn cut through him like a whip.

He fed on a local,” she blurted out.

Kyle immediately tucked his head between his arms in a posture of pure shame. “I know the agreement, Ms. Tatiana, but—”

He didn’t get to finish the sentence. In a blur of motion that defied the laws of physics, Tatiana was across the table. She grabbed Kyle by the hair, slamming his head back as she pressed her sword against the base of his skull.

She moved so quickly that his siblings’ predatory instincts couldn’t even register the threat until it was too late. Her eyes ignited into a lethal, radiant lavender, and dark veins pulsed at her temples.

Both Kameron and Kaitlyn scrambled to their feet, their faces etched with pure terror. “Tatiana, please!” they shouted in unison.

“We agreed that you do not feed on the locals!” she shouted back, her words like sharp glass.

“You know what comes after if you do!”

“You’ve signed your own death warrants!”

“The human is not dead!” Kyle screamed, his voice cracking as he felt the cold bite of the steel. “She’s at the hospital, but she told the doctors everything…and now they’re coming after us.”

Tatiana’s grip tightened. “Who’s coming after you?” she whispered. Who is more powerful than the Montagues?”

Kameron stood as tall as his shaking knees would allow, “The VCI.”

Tatiana went still, the air leaving her lungs as if she had been punched. She let go of Kyle’s head and turned to Kameron with a hollow, haunted expression. “How do you know this for sure?”

Kaitlyn opened the folder and handed her an envelope with a heavy, crimson wax seal. Tatiana didn’t have to open it; the crest alone confirmed the nightmare. She sat back down, the room falling into a silence that was like a funeral knell.

“Please, you have to help,” Kameron whispered. “You know if they come into the city, it’s over for everyone—including your kind.”

“I’ve heard enough,” Tatiana said softly, the lavender glow in her eyes fading into a dark, cold grey. “Which hospital is the human in?”

Tatiana knew she was the only living soul capable of standing in their way. She was the only one who had ever survived a direct encounter with a member of the Vector Control Initiative.

For 120 years, she had been an elite hybrid-killer, a force of nature that cleared the city of anything that disrupted the peace. But the VCI was different; they were the ones who had burned her village and murdered her entire race.

She was fifteen when the sky turned orange with fire, leaving her as the survivor of a dead lineage. She was a special breed of hybrid—an assassin whose lavender sight could predict an opponent’s every move.

Her blood was a lethal poison to vampires and wolves alike, and she could mimic the abilities of her prey to use against them. She had been a child soldier, forced to master the art of death because her kind was hunted for the power they carried.

“The Fires That Never Dies,” they called her, a reference to her unmatched speed and her dual-wielded blades.

Fifty years ago, her mandate had been to exterminate the Montagues, until she realized they weren’t the monsters she had been told they were. They had forged a pact: they could remain in the city as long as they fed only on animals and the wicked.

But the food chain was collapsing, and the animals were disappearing from the urban sprawl.

Humans had become too afraid to commit crimes because of Tatiana’s reputation, leaving the vampires starving. She knew these vampires couldn’t survive on scraps forever.

The Montagues hadn’t tasted human blood in twenty-five years, and that hunger was a beast that eventually broke its cage.

“There has to be a balance,” Kaitlyn said, her voice visibly shaking. “We are slowly decaying; we haven’t had real blood in years because of this stupid agreement.”

“Watch your tongue,” Tatiana said, her voice echoing the authority of a queen. She stood up, “I will help you during this crisis and retrieve the human.”

“But hear me well: control your urges, or I’ll be the last thing you ever see.”

She turned to leave, but her eyes instinctively found Kameron’s.

For a split second, the strategist’s mask crumbled. In the silent bunker, there was an unspoken language between them—fifty years of shared secrets, near-misses, and connection that blurred the line between hunter and prey.

He didn’t look at her with fear this time. He looked at her with a desperate, silent plea that made her chest tighten.

“Titi.”

The word was a whisper, barely audible over the hum of the ventilation.

Tatiana froze.

No one had called her that in decades. It was the name from the part of her life she never talked about anymore—the part she buried and refused to revisit. A name only Kameron knew.
