They gave him 24 hours to hand over the girl.
He gave them 30 seconds to regret .

Jack Cole was supposed to be nobody—just another quiet college student.
No records. No past. No trace he ever existed.

But when a powerful family tries to take his cousin as part of a dirty deal…
and a billionaire heiress becomes the target of a professional kill team…

Something buried comes back.

The campus?
Just his cover.

The truth?
He’s a weapon trained for war—
the kind governments deny, and enemies never see coming.

Now the richest family in the city wants him dead.
A private army is moving in.
And a global biotech empire is pulling strings from the shadows.

They think they’re hunting him.

They’re wrong.

Jack isn’t running.
He’s choosing who dies first.

In their eyes, my wife Emma—an Ivy League tenured professor in biological sciences—is ruthless, rational, and obsessively clean.
For seven years, even when she washed her hands, she would only ever touch the right-side sink—hers.
Until that night at 3 a.m., when I pulled a strand of sandy-golden short curl—hair that belonged to neither of us—out of my men’s shower loofah.
And around the neck of a pre-med student named Lucas, I saw the antique silver cross my dying father left in my hands.
When I confronted her, my always-icy wife protected the little homewrecker, slapped me across the face, and called me a jealous, controlling chauvinist.
She thought I’d swallow it like a coward.
But she forgot: as a top cardiothoracic chief, the thing I do best is cutting out tumors.

The Percy Family Heir's Scandal Leaks Again!

Cecilia Davis sat curled up in the master bedroom, scrolling through photos of Edward Percy and Jessica Brown.

The photos were taken secretly, but from a sharp angle.

Through a car window — the two of them, going at it hard.

Cecilia let out a cold laugh, tossed the photos into the trash, and felt a wave of deep exhaustion wash over her eyes.

"Do I really have to cut it?"

"Ma'am, this is Mr. Percy's request. Only if you cut your hair as short as Ms. Brown's can we clear up last night's rumors. Of course, you don't have to go — that is, if you never want to see your brother again."

Edward's assistant Leo spoke with a dismissive air, not a trace of respect in his eyes.

As if she, the so-called Mrs. Percy, was nothing more than a joke that nobody needed.

And honestly, that's exactly what she was.

On a stormy night, a horrific crash unfolded on the overpass. The victim was brought to the city forensic center.
My husband, Ethan, slipped on his gloves and expertly examined my shattered body, his voice detached. "Record this: Female, approximately twenty-five years old, suffered severe trauma before death."
His assistant sighed. "That's rough. Not a single family member showed up."
Just then, the assistant slid a misshapen silver band off my mud-streaked finger.
"Sir, this ring... isn't it identical to the one you keep in your desk drawer?"
With a sharp clatter, the scalpel slipped from Ethan's hand and hit the floor.

Because of the strong desire to give her mother the best treatment after her stroke, Samantha was forced to accept the offer to dance for a client, Mr. MC. She is the private sexy dancer of a wealthy man.

She hasn't seen his face, not even once, because he always wears a masquerade mask when she dances in front of him. She needs to give him a good show to warm his night just by dancing.

Just watch, no touch, that's it!

Does she have the right to fight how he feels about him if their agreement ends when the woman he was supposed to marry returns?

What? She married a wrong guy? It wasn’t the person who was going to marry her but someone else?
After the death of her boyfriend, her family sold her off, in the name of marriage, to the wealthiest family of the city in order to pay back their debts. The condition was: She has to give birth to the Reynolds’ family’s heir within a year!
Sienna Millar always thought that, she replaced her sister to marry the foster son of the Reynolds’ family. But what she didn’t know was she actually married the real heir of the Reynolds’ family!
Ezekiel Reynolds, the real heir of the Reynolds family, the business emperor and the prince charming of the city, married the daughter of Millar family because his brother didn’t want to do it. After marriage he didn’t even see the woman he married. But what he didn’t know was he actually married the woman he always liked!
Sienna who always thought Ezekiel as his brother-in-law and Ezekiel who always thought Sienna pretended to be married were unknown that they were actually husband and wife!
When Sienna found out the person she married was actually Ezekiel, she was stunned, “I married a wrong guy? Aren’t you my brother-in-law?”
However, Ezekiel pressed her against the wall, saying evilly, “Why? Are you unsatisfied with your mistaken husband?”

I was nothing but a wolfless omega—a slave in the Mistveil pack, invisible to everyone except as a target for their cruelty. For years, I secretly dreamed of Drary Vesper, the alpha’s son, believing he could be my escape. But when the Moon Goddess revealed he was my fated mate, he didn’t embrace me. He rejected me. Publicly. Brutally. In front of the entire pack and his vicious lover, Gwendolyn.

That night, drowning in pain and my first heat, I stumbled into the one man I should have avoided: Axel Vesper. The ruthless, silver-eyed Alpha who rules with an iron fist and is rumored to have killed his own wife. He’s cold, commanding, and twice my age. He’s also Drary’s father.

One night of vulnerability changed everything. Now, my body is changing in ways I don’t understand, and someone is poisoning me from the shadows. When Gwendolyn tries to burn me alive, my wolf finally awakens—not to save me for Drary, but to deliver me into the hands of a rival pack... and a mysterious man with warm golden eyes who looks at me like I’m something precious.

But Axel hasn’t forgotten me. And in a world where alphas rule and omegas are discarded, the most dangerous monster of all might just be the one who wants to claim me as his.

A gang boss ground my treasured staff into dust with one boot. “A gutter-bred bastard from the slums, and you’re hiding something this delicate? Cripple him. Let him learn who runs this turf.”
I stared at the silver-white powder on the floor. It was the last relic my brothers left me.
I once swore these hands would be used only to save people, never to kill again.
But today, even the heavens refused to allow it.
I lifted my head slowly. The elven ears I’d kept lowered in submission rose one by one in the dark, sharp as a wolf’s.
“You’re asking me who runs this turf?”
My fist snapped out and caved in the boss’s nose.
I twisted backhanded. Three elite enforcers had their bones shattered in an instant, collapsing like sacks of rotten meat.
I grabbed the boss by the throat with one hand and hoisted his two-hundred-pound body into the air, eyes cold as if I were staring at a corpse.
“Three years ago, when I laid down the rules in this district, you didn’t even know where you were playing in the mud.”
“My things are not for you to touch.”

The global freeze descended, and the apocalypse arrived right on cue. I seized all the critical supplies and evacuated first, leaving "the perfect base" behind for the two traitors who backstabbed me. They thought it was heaven, but little did they know that the entire fortress was a precision trap constructed of deception, scarcity, and despair. As the outdoor temperature plummeted to minus eighty degrees, I sat by the window, roasting venison and watching them through high-definition infrared, coldly observing as they lost their humanity in the desperate fight for a single bowl of sawdust.
