Bloodline Betrayal: The Alpha Sister's Revenge

The 0% DNA match report and a thick stack of lawsuits slammed onto the expensive mahogany conference table. Sixteen years ago, in the penthouse VIP maternity ward, someone deliberately swapped my biological sister, stealing the billion-dollar trust fund meant for her.

Now, this parasite of a thief stood there in her haute couture gown, squeezing out perfect, pitiful tears. I didn't even waste a glance on her.

In the corner, Clara trembled. She wore a threadbare, faded T-shirt. A fresh, bloody gash stood out on her foreheada gift from Earl, her alcoholic adoptive father, who smashed a cheap beer bottle over her head yesterday in their rundown trailer park.

I reached out. She flinched hard, her shoulders jerking up to her ears.

Blood roared in my ears, snapping my last shred of restraint.

I marched right back to the center of the room and backhanded Harper across the face.

A sharp, echoing crack.

"Take your knockoffs and get down to the windowless storage room in the basement. Hand over all your supplementary black cards."

I completely tuned out my parents' hysterical screaming, gently pulling my bruised and battered sister to my side. "Don't be scared," I said, carefully wiping the dried blood from her cheek. "I run this house now."

Chapter 1

The call from my father came out of nowhere. I was just wrapping up a cross-border M&A meeting, the opposing counsel's relentless haggling still ringing in my earpiece. The word "Dad" flashed on my screen. A heavy, sluggish feelingcompletely unrelated to business negotiationssettled in my chest.

"Astrid." His voice crackled through the line, unusually dry. "You you need to come home right now. It's about your sister"

I held up a hand, signaling my assistant to pause handing over the next stack of files, and walked over to the floor-to-ceiling window. Beneath my feet, the city's grid of lights flowed like a rivercold and perfectly ordered.

"What kind of mess did she make at school this time? Do I need to contact the board to kill the story?" I didn't even try to hide the impatience in my voice. That spoiled, lawless brataside from maxing out my credit cards at Beverly Hills boutiques, her ability to stir up trouble was directly proportional to her arrogance.

"No, it's not that" My father rushed to deny it. He took a ragged breath, like the words burned his tongue. "It's we just got her medical reports back. Her blood type doesn't match. We rushed a DNA test Astrid, your sister, sheshe isn't biologically ours! There might have been a mix-up at the hospital back then!"

The conference room lights were blindingly bright. I caught my own blurred reflection in the glass, a sharp crease forming between my brows. A mix-up?

"Dad." My voice dropped an octave. "Did you forget? When Mom gave birth to her, she was staying in the top-floor VIP maternity suite at our family's private hospital. They only admitted one expectant mother that entire month. Where exactly would another baby come from to get mixed up with?"

My father stammered. "But the DNA report"

"Reports don't lie. People do." I tapped my fingernail against the freezing glass. "I'm heading back now. Don't do a single thing before I walk through that door. Keep Mom in check."

I cut the call. I didn't move toward the door immediately.

Instead, I hit the direct line to my head of security. "Pull the security footage from sixteen years ago. I want the records from the top-floor VIP maternity suite and the nursery at our private hospital, covering the exact day of my mother's delivery, plus the days before and after." I paused. "Authorization requires my biometric clearance. Route all files directly to my private server. Top secret."

"Ma'am, footage from over a decade ago the archival systems have been updated multiple times since then. It might take a while"

"Then start digging." I didn't raise my voice, but the line went dead silent on his end. "You have exactly one hour."

Chapter 2

An hour later, the stretch Lincoln tore down the highway toward the family estate. On my lap, the tablet screen fractured into grids, flickering with grainy security footage from over a decade ago.

My mother was wheeled into the delivery suite. In the hall, my father paced, surrounded by a few arriving family elders. A nurse stepped out with a swaddled infant. My father broke down in tears.

I scrubbed forward on the timeline. Everything looked flawless.

Until the second night.

A figure in scrubs and a surgical mask appeared at the nursery entrance. Her fingers hovered with slight hesitation before punching in the passcode. She carried a swaddled infant.

Three minutes later, she exited, still clutching a bundle to her chest. She practically sprinted down the corridor, vanishing around the corner.

On the top-tier VIP ward, the night shift required two fixed nurses with clear handover logs. At that exact time, of the two nurses supposed to be on duty, one had signed out for seventeen minutes. The other

I pulled up the staff logs to cross-reference. My eyes narrowed. The height and build of the figure on screen completely contradicted the personnel file for the registered nurse on duty, Maxine.

A private hospital. The top-tier suite. Maximum security. A phantom nurse had materialized out of thin air to swap my mothers two-day-old newborn.

I pressed my freezing fingertips against the screen, hitting pause. I zoomed in on the grainy figure. This wasn't a clerical error. This was a calculated theft.

The stretch Lincoln glided through the estate's wrought-iron gates. The sweeping headlights washed over the pale, anxious figures clustered by the marble fountain.

My father, my mother, and the parasite clinging to her chestHarper.

The car rolled to a halt. The butler pulled the door open. I stepped out into the night air.

I bypassed my fathers panicked expression and my mothers swollen, bloodshot eyes, locking my gaze straight onto Harper.

She tilted her chin up, draped in the latest season's Chanel haute couture. Perfect, crystalline tears tracked down her sweet, delicate face, but behind the wet lashes hid a sharp glint of smug greeda silent vow that she would never let her claws slip from this massive fortune.

"Astrid" she whimpered, reaching out to grab my hand.

I sidestepped, letting her manicured fingers grasp empty air. I didn't waste a single second looking at her, fixing my eyes entirely on my father. "Where is she?"

My father blinked, stunned. "Who?"

"My sister." The words dropped like ice into the crisp night air. "The one who was stolen. The real blood of this family."

My mothers head snapped up. "Astrid!" she shrieked. "Harper is standing right here! How could you"

"Mom." I cut her off. My voice barely rose above a whisper, but it snapped her jaws shut instantly. "Save the touching mother-daughter routine. Especially for a total stranger with zero pedigree."

I swept my gaze over Harper, watching the color completely drain from her powdered cheeks. "Where is she?"

My father swallowed thickly. "Waiting in the side parlor."

I turned my back on my mothers stifled sobs and Harpers crumbling facade. I marched straight through the grandiose, freezing marble foyer, heading for the parlor.

The heavy oak door was slightly ajar. I pushed it open.

The lights were dimmed. A small figure was curled into a tight ball on the leather sofa. At the click of the latch, the silhouette flinched violently, her head snapping up in pure panic.

It was a face carved from the exact same mold as my late grandmother in her youth. But the cheeks were hollow, completely drained of color. A faint, reddish scar still lingered on her temple.

Her eyes were massiveeyes that should have been bright and commandingbut right now, they were drowning in raw, instinctual terror. Like a cornered stray bracing for the next kick.

Chapter 3

She wore a threadbare, oversized shirt that swallowed her frame. Her fingers twisted together in a tight knot, the cuticles chewed raw and bleeding. As her eyes met mine, her shoulders jerked, pulling backward in an instinctual flinch.

Deep in my chest, a sheet of ice cracked wide open.

I closed the distance. I forced my strides to slow, stopping a few paces away. I crouched down, bringing my eyeline dead-level with hers.

"Don't be scared." The softness of my own voice surprised me. "My name is Astrid. I'm your older sister."

She blinked. Fine tears clung to her long lashes. She stayed completely silent.

I reached out, letting my fingertips brush the edge of the scar on her temple.

A violent shudder ripped through her.

The wound was raw.

"Who did this?"

Her bottom lip trembled. When she spoke, her voice was a thick, muffled whisper. "Earl. He was drunk."

The floorboards creaked by the parlor entrance. My parents had followed me in. Harper wedged herself beside them, biting her lip as she stared at us.

I lowered my hand. I didn't stand. I merely turned my head, sweeping a glacial gaze over the two oblivious parents in the doorway and the parasite who had stolen sixteen years of a life that wasn't hers.

I shifted my focus back to the bruised, trembling girl on the leather sofa. I pitched my voice so every single person in this estate could hear it.

"From this day forward, no one will ever lay a finger on you again. I run this house."

I took Clara by the hand and led her up to the second floor. Her fingers vibrated against my palm like a terrified bird. Small, faded scars mapped across her knuckles.

"This is your room now."

I pushed open the double doors to the sunlit suite right next to mine. After I gave the order this afternoon, the household staff had overhauled the space with terrifying efficiency.

Soft champagne gold and pearl-white undertones warmed the room. Top-tier Egyptian cotton dressed the king bed. The walk-in closet hung heavy with the latest season of Herms and Dior, the price tags still dangling intact. A custom Bvlgari jewelry box sat on the vanity alongside a complete lineup of La Mer skincare.

A faint, comforting warmth filled the air.

Clara's feet locked onto the threshold. Her eyes widened, tracking the suffocating luxury like a stray bird trapped in a gilded cage. Absolute panic, zero joy.

"Not to your taste?" I asked.

She shook her head violently. Her fingers twisted the hem of her shirt. "It's it's too much," she whispered. "I I don't deserve this."

"Nonsense." I cut her off, my tone leaving zero room for debate. "You are the blood of this family. You are my biological sister. This is just the baseline. You deserve every single perfect thing in this world."

I guided her inside and slid the closet doors open. "Check if the sizing works. If not, I'll have the brands send fresh inventory."

She reached out, her fingertips barely grazing the cuff of a silk dress, terrified she might ruin it.

That ingrained, flinching subservience spiked my adrenaline. I wasn't angry at her. I wanted to burn the people who had broken her to the ground.

"Astrid" Her voice wavered, loaded with doubt. "Can I can I really stay here? You won't kick me out?"

Chapter 4

I turned, gripping her bony shoulders and forcing her to meet my eyes. "Listen to me, Clara. This is your house. Someone stole your life, but you're back now. No one is kicking you outespecially not that thief. Stand up straight."

She barely understood, but under my stare, she gave a slow, tentative nod.

I settled her in and headed downstairs. My father sat on the leather sofa, massaging his temples. My mother was still sobbing. Harper remained glued to her side, rubbing her back in a sickening display of mother-daughter bonding.

The moment I walked in, Harper blinked out fresh tears. "Astrid, I know you're angry, but Mom's health is fragile. Please don't stress her out anymore. It's all my fault. I shouldn't even be in this house"

Perfect, pitiful tears.

I didn't even entertain her little performance. I looked straight at the butler. "Niles, clear out the guest room on the west wing for Harper. From now on, you personally oversee Clara's meals and daily routines. If anything goes wrong, I'm holding you responsible."

Niles bowed. "Yes, ma'am."

My mother's head snapped up. "Astrid! How could you do this? Harper is still"

"Still what?" I shot back, my gaze freezing her in place. "A complete stranger with zero pedigree who played parasite for sixteen years? We haven't pressed charges against her or the masterminds behind this fraud. That's mercy. Did you really expect us to keep funding her trust fund?"

"How can you be so cold-blooded! I raised Harper with my own two hands!" My mother shot up from the sofa.

"Yeah, you raised the thief who stole your biological daughter's life." I kept my tone deadpan, every word a serrated blade. "You spent the last sixteen years at country club tea parties, enjoying the perfect mother-daughter roleplay, using someone else's kid. Meanwhile, your actual flesh and blood was getting abused by a drunk in a trailer park, eating expired food stamps, and wearing torn rags from the thrift store."

I paused, letting it sink in. "Your little roleplay came with a heavy price tag, Mom."

The blood completely drained from my mother's face. She stumbled back, caught by Harper's waiting arms.

"Astrid, how can you speak to Mom like that!" Harper cried. "I know you hate me, but Mom is innocent!"

"Innocent?" I scoffed. "Turning a blind eye to a crime and being too stupid to see the truth is the biggest guilt of all."

I dismissed them entirely and turned to my father. "Dad, security already has initial leads on the fake nurse from back then. I am ripping this whole thing open."

My father opened his mouth, but just gave a weary wave of his hand. "Do do whatever you see fit."

I walked out of the living room, leaving the muffled sobs and fake consolations behind.

Over the next few days, I stayed buried at the corporation, tearing through the backlog of work caused by my sudden return. But I checked in with Niles every single day. The reports were always the same: Clara was quiet, ate her meals in her room, rarely ventured out, and showed zero interest in the wardrobe or the jewelry.

Until the fourth night. I wrapped up a video conference early and headed back to the estate, bypassing the security gate without having the staff announce me.

I walked up to the second floor. As I passed Clara's suite, sharp, muffled sneers bled through the heavy mahogany door.

"trailer trash is still trailer trash. You could wear a crown and you'd still look like a rat."

"Did you seriously think walking back into this estate makes you an heiress? Look at you shaking. It's pathetic."

Chapter 5

"Heard your adoptive dad's a drunk. And your mom ran off with some guy? No wonder you reek of trailer trash."

Harper.

I shoved the door open.

Harper stood by the vanity, flanked by two maids who usually kissed her ass, circling Clara. Clara wore a light blue designer dress, but a massive, dark stain of juice soaked the entire front. She kept her head down, her shoulders hunched inwards like a cornered stray. Her teeth dug into her bottom lip, her face a terrifying shade of pale.

"What the hell is going on here?" The temperature in the room plummeted.

The two maids flinched, dropping their gazes and pressing themselves flat against the wall.

Harper flinched, but quickly pulled her mask back up, pasting on a pitiful pout. "Astrid, you're back? It's nothing. I just accidentally spilled some juice on Clara's dress. I was just about to help her wipe it off."

"Is that so?" I walked over, my eyes sweeping over the half-empty glass on the vanity and the tiny flecks of fruit pulp clinging to Harper's fresh manicure. "You walked all the way from your room, holding a glass of juice, and 'accidentally' splashed it dead-center on her chest? Your accidents have sniper-level precision, Harper."

Harper's expression slipped. "Astrid, you're misunderstanding"

I ignored her completely. I looked at Clara. "Is she telling the truth?"

Before Harper could even blink, I reached past her, snatched the half-empty glass off the vanity, and dumped the rest of the juice directly over Harper's head.

The sticky, dark liquid dripped down her perfect blowout and smeared her flawless makeup. She let out a piercing, pig-like squeal
