He Killed My Brother, But I Took My Revenge

“Did she get everything? The clothes, the bags, the flowers... all of it?”

Cain’s voice was tight, nearly clipped. I stopped dead in front of the door, its crack barely enough to peek through.

“Yes, Alpha Cain. Everything was handled discreetly, just like you ordered,” David, his most trusted warrior, responded swiftly.

My stomach twisted. My birthday gift was only a bouquet of white roses and pearl earrings. It felt cheap, like an afterthought. Cain hadn’t even remembered my favorite flower.

“And the doctors? Were they careful? How’s she holding up?” Cain continued.

“No answers. Still brushing off Athena’s chest pain as a side effect from the transplant.”

Athena? Athena Dawser? The female Alpha who had rejected Cain a year ago, the woman who’d called him weak for a Beta from a failing pack. Why was Cain so obsessed with her now?

“Alpha Cain never truly loved Luna Esme. She was just a rebound after Athena.”

I’d dismissed it then. Now, that gossip echoed, loud and sharp.

“Useless doctors. They must’ve messed up when they transplanted Noah’s heart,” Cain growled in frustration.

My blood ran cold. Noah. My twin brother. My head spun. What was he saying? Noah’s heart?

“Rumors are spreading, Alpha Cain,” David murmured.

“People think Noah’s death wasn’t an accident. And they’re saying you went ahead with the heart transplant... without Luna Esme’s consent.”

Cain’s voice dropped lower, colder, angrier but controlled.

“Athena’s life was worth more than Noah’s. She was dying, David. She needed the heart. I couldn’t let her die. Noah was good as dead, anyway. Using his heart was the only thing left. Don’t worry about Esme. She’s... she’s too naïve. She loves me. Blindly. But silenced those rumors.”

My legs went weak. My twin—dead. Gone. For her.

I staggered back, my pulse thundering. I turned and ran to our room. My hands trembled as I slammed the door shut behind me, ripping through Cain’s things—papers, clothes, anything I could find. I needed to prove this was a lie.

Then, I found a box.

Inside were hundreds of photos of Cain and Athena—laughing, holding hands, kissing.

No.

But one photo froze me. They were naked, locked in a passionate kiss on a yacht in Lake Como. My yacht.

Then, an envelope with pictures of Noah’s disgruntled body and a note.

“I’ve done the job. Enzo will take care of the body. Rule it as a car accident. Make sure his twin signs the heart transplant agreement. Full payment in two months.”

Cain had been there when Noah died. He held me, pretended to be my rock, as my world shattered. But he... he killed him.

My heart cracked. My wolf howled, clawing to break free. Kill him. Tear him apart. But I hushed her.

Later that evening, the pack gathered for the banquet. Cain’s arm was possessively around my waist. His smile was nothing but a mask; it never reached his eyes. My own smile felt like a lie, too.

“Luna Esme, you look... well,” Elder Thorne’s gaze lingered on me, pity, always pity, since Noah’s death. “Still grieving?”

Cain chuckled, pulling me closer.

“My Luna is strong. She simply misses her brother.”

His words were smooth, rehearsed. His touch on my hand was a show, a performance for the pack.

Then, Athena entered.

The room silenced. She was a walking goddess. Emerald green eyes sparkling with a confident smirk. Cain’s grip on me tightened, but his gaze locked on her, hungry for her. My stomach churned.

He released me and walked towards her.

“Athena,” he murmured, soft and intimate, a tone he hadn’t used to me in months. He kissed her knuckles right in front of me, in front of the entire pack.

Whispers erupted.

“He never got over her.”

“Poor Luna Esme.”

“Just a placeholder.”

Each word sliced through me like a blade. I stood there, humiliated and discarded. I was his mate, Luna of the pack, a pack I inherited from my Alpha father. Yet here I was, invisible, while he adored another.

One of Athena’s assistants sneered at me, her eyes cold.

“Heard you’re not allowed to leave the grounds, Luna. Alpha Cain’s orders for your ‘safety’. Or is it to keep his little secret?” she whispered with a smirk.

I paled. A prisoner. That’s what I was. My pack. My mate. My brother. My life. All stolen.

I was about to faint when I felt a hand on my arm. It’s Lyra, Noah’s best friend, eyes wide with concern.

“Luna? Are you alright?”

I pulled away.

“Fine.”

The word tasted like ash in my mouth. I didn’t want their pity. Cain had made me a fool. A public spectacle.

Across the room, Cain and Athena laughed. Their heads bent together; their whispers laced with intimacy. He touched her possessively like he used to do with me. No. Like he never did to me.

Then, the music, laughter, and clinking glasses all faded into nothing. The ringing in my ears drowned out the world. All that remained was Cain. And her.

He had orchestrated everything. All to get her heart. All to get her. And I was just a convenient pawn.

A cold fury spread through my veins. My wolf roared silently, demanding blood. But no. I wouldn’t be hasty. Death was too quick and easy. My blow must be precise, methodical, and painful.

I was Noah’s twin sister. We, the twins, were ruthless and genius strategists of the Shadowhunter Pack.

“You took everything from me, Cain. Everything. And I will make sure you pay—in double,” I whispered and turned to walk away.

With the agreement, I stormed into Elder Thorne’s office without a knock.

"I want to sever my mate bond with Alpha Cain," I declared.

Elder Thorne froze, eyes wide with shock.

"Luna Esme, what happened?"

“I want the link severed. Now,” I snapped.

"But Luna, this bond is sacred, unbreakable."

“It’s already broken,” I shot back, my gaze like steel.

“And I renounce my title. However, as my father ensured before his death, I still get 90% of my inheritance. I'll be back tomorrow to ensure all my money is in my account and my properties are no longer free for him to use.”

I slapped the agreement on his desk and headed to my room to start packing.

“Esme, what is this I hear about you causing a scene with Elder Thorne?” Cain asked in a low growl as he barged into the room the next day.

My heart hammered against my ribs, but I managed to say, “Simply tying up loose ends, Alpha. Some affairs you’ve clearly overlooked.”

Cain’s jaw clenched.

“Loose ends? What nonsense are you spouting now, Esme?”

“The kind that demands attention,” I countered. I held up a folded document, carefully obscuring the crucial details.

“And this. A minor legal formality. My family’s lawyers are particularly… insistent about some old trusts being finalized tonight. They say if it’s not signed, it could cause complications for your leadership. Just a quick signature, Alpha, and I promise, my family’s ‘drama’ won’t be in your way.”

He scoffed, waving a dismissive hand.

“Too much drama. I have more important things to deal with than your tedious paperwork.”

“Of course,” I said, my voice sweet as poison. I stepped closer, ensuring the faint scent of my perfume, the one he once claimed to adore, reached him.

“Just a simple signature, Alpha, unless you’re afraid to sign something with your Luna by your side?”

His eyes narrowed.

“Don’t be ridiculous, Esme. I don’t need you to sign my papers.”

He snatched the document and the pen from my hand, his gaze flicking to the blank line with his name. He scribbled his signature in a rush.

“There. Done. If you’ll excuse me, I have important pack matters to attend to,” Cain said, gazing at the door.

A sharp, searing pain suddenly exploded in my lower abdomen. My breath hitched, and a strangled gasp caught in my throat as I gripped the dresser, feeling the room spin.

“Esme? What’s wrong with you now?” Cain’s voice was distant, annoyed.

But then, a frantic knock echoed, sharp and insistent.

“Alpha Cain! Athena needs you! It’s urgent! She is having another chest pain!” David’s panicked yell pierced through the haze of my agony.

Cain’s head snapped towards the door, all annoyance vanishing, replaced by an immediate, desperate concern. He didn’t spare me another glance.

“Coming!” he roared, already halfway out the door, then gone.

The pain intensified into a twisting, wrenching agony that stole my breath. I slid to the floor, gasping, vision blurring with unshed tears from how Cain had just walked away.

He never chose me.

A painful memory of the annual Moon Festival flashed before my eyes. It was after Cain became Alpha of the Shadowhunter, a position he’d secured after Noah’s death, and by being my mate. The bonfire blazed, music swelled, and wolves from different packs danced and sang with uninhibited joy. Cain stood beside me, his arm loosely around my waist.

Then, Athena appeared on the edge of the clearing. Her silver dress shimmered in the firelight; her smile was directed specifically at Cain. A collective gasp rippled through the gathering as a rogue wolf, disoriented and aggressive, lunged directly for her.

The pain erupted again, hotter this time, a gush of warmth spreading between my legs. My hand instinctively went down. Wet. Sticky. Blood. A lot of blood.

A strangled cry escaped my lips. I tried to push myself up, but my arms gave out. Darkness began to creep into the edges of my vision.

The last thing I heard before the world dissolved was the faint, mocking echo of Cain’s voice: “Athena’s life was worth more.”

The rhythmic beep of a machine awakened me. My head throbbed, and I felt disoriented.

“Luna Esme? You’re awake.”

A nurse, face etched with pity and concern, hovered over me. She reached for my wrist, checking my pulse.

“What happened?” I whispered.

She hesitated, her gaze dropping to my abdomen.

“You… you had a severe hemorrhage, Luna. We did everything we could, but… you lost the baby.”

The words struck me like a blow, stealing what little air remained in my lungs. My baby. Cain’s baby.

“No…” I whispered, tears tracing hot paths down my temples.

“I’m so sorry, Luna,” she murmured. “You were… about two months along. But the bleeding... it was too much.”

The exhaustion, the nausea I’d dismissed as mere fatigue – a life had been growing inside me, and now, it was gone, smashed like everything else.

“Did you… did you call Cain?” I choked out, a desperate, foolish hope flickering.

The nurse’s expression hardened, a flash of anger in her eyes.

"We tried, Luna. Multiple times. We were told by Alpha Cain’s personal assistant that you were ‘faking it for attention.’ That you were just ‘overdramatic.’ He said he would ‘come by tomorrow, if he had time’".

Faking it. Overdramatic. His words, raw and contemptuous, sliced through me. He hadn't just neglected me; he had condemned me and our child. The last glimmer of love, hope, and any attachment to him was extinguished.

"Get me the discharge papers," I said, my voice steady despite the tremor in my hands. "Now".

The nurse looked surprised.

"But Luna, you’re not stable yet. You need rest".

"I need to leave," I corrected, pushing myself up despite the protesting agony in my core.

"I’m not staying here another second. Arrange a car. I’m going home".

She nodded slowly, recognizing the unyielding resolve in my eyes, and left the room.

The mansion was alight with laughter and music when the cab pulled up. I walked through the main doors, my dress still stained with blood, every eye turning to me. Whispers started immediately, but I ignored them, my gaze fixed on Cain by the grand fireplace. He was laughing, a hand possessively on Athena’s back, her head thrown back in amusement.

"Luna Esme, you look… unwell," Athena murmured, detaching herself from Cain and gliding towards me. Her eyes, narrowed with a practiced concern, swept over my disheveled appearance. "Heard you had a little… incident. I was worried".

"Unlike some, I don’t stage my misfortunes for attention," I retorted shakily.

Her smile faltered but quickly reformed into a mask of fake sympathy. "Still so pale, Esme? You should really take better care of yourself".

Just then, Cain approached, his eyes cold and devoid of concern. "What are you doing here, Esme? And in that… state?"

"I came home, Cain. Something you seem to have forgotten how to do," I replied.

Athena, ever the instigator, feigned a gasp.

"Oh, dear, did you just hear that, Alpha Cain? Luna Esme sounds quite upset. I do hope she isn’t going to cause a scene".

Cain’s gaze sharpened on me.

"What is she talking about, Esme?"

"Ask your precious Athena," I challenged, gesturing towards her. "She seems to be the expert on stirring up trouble."

Athena’s eyes narrowed, and malice replaced her facade.

"How dare you, Esme! I was simply trying to calm you when you, in a fit of rage, tried to push me into the swimming pool last banquet!"

A collective murmur rippled through the crowd. All eyes were on us, sensing the escalating tension.

"That’s a lie!" I seethed. "I was never around you that night."

Cain’s face darkened.

"Esme, that’s enough! Apologize to Athena. Now!"

My jaw tightened at his order. Apologize? To her? After everything?

"I will not," I stated firmly. "I have nothing to apologize for".

A dangerous glint appeared in Cain’s eyes. He took a step closer, towering over me.

"Since you insist on making a spectacle, perhaps you need to cool down."

The next second, I was airborne. A hard shove sent me stumbling backward, off the polished marble, past the gasping guests, and into the frigid depths of the swimming pool. The shock of the cold water stole my breath, and the impact sent a fresh wave of agony through my stillrecovering body. I surfaced, gasping, the pool lights illuminating my humiliation. Laughter, hushed at first, then erupted. Athena’s delighted cackle rose above the rest.

Cain stood at the pool's edge, looking down at me with cold satisfaction.

"Perhaps that will teach you some manners, Luna Esme".

I pulled myself out, dripping onto the pristine pool deck, ignoring the stares and whispers. My wolf inside me howled in rage, a primal scream I was gasping to control. I rushed towards the room before I lost myself and let my wolf control me.

Since throwing me into the pool, Cain hadn’t returned home for three days. Not a call, not a text, not even a sneering insult. It was as if I’d ceased to exist. But I wasn’t rotting in my room. Today was the annual Wolf Pack Auction, and among the artifacts was my grandmother’s locket, a delicate silver piece with intricate carvings stolen years ago and now resurfacing.

I arrived at the auction house; my head held high. Cain was already there, of course; Athena draped on his arm, her laughter echoing loudly, grating on my nerves. He spotted me, and for a split second, his smirk faltered. Good.

My heart hammered when the auctioneer announced lot 27, “A silver locket, believed to be from the revered Shadowhunter lineage.”

“One million,” I stated, cutting through the murmurs.

Cain’s head snapped towards me. He hadn’t expected me to bid, let alone so aggressively. Athena whispered something in his ear, a triumphant smile on her face.

“Two million,” Cain countered.

“Five million,” I shot back, my gaze locked on his.

His jaw clenched. “Ten million.”

The room went silent. Confusion rippled through the crowd, wondering why we were locked in a bidding war over a mere locket.

“Twenty million,” I said, unwavering.

Cain’s eyes glared with desperation. He raised his paddle, then hesitated. He pulled out his phone, a sinister glint in his eyes.

My phone vibrated. I opened the message. A photo. My grandmother, frail and vulnerable, hooked to life support, a nurse adjusting the tubes. And a message: “Go higher, Esme. Your grandmother’s life support has an off switch. I could have it switched off anytime.”

My breath hitched. I closed my eyes, fighting back the rising bile. He couldn’t. But he had killed Noah. He had discarded our baby. He was capable of anything.

I lowered my paddle, my hand trembling.

“No bid,” I rasped, the words tearing through my throat.

Cain smirked, a cruel, victorious smile spreading across his face.

“Fifty million,” he announced, winning the locket.

Then, he came to me, holding the locket.

“Such a shame, Esme,” he whispered, his voice filled with malicious glee. “Your grandmother looked like a witch wearing this. It deserves to be worn by someone like Athena.”

I didn’t answer. I turned and sought refuge in the ladies’ room. I splashed cold water on my face, trying to compose myself.

The door creaked open, and Athena sashayed in, her dress shimmering.

“Oh, Luna Esme,” Athena purred, her eyes glittering triumphantly.

“Still reeling from losing that locket? Such a pity. I’m sorry I told Cain to give it to you, but he insisted that it looked better on me."

“You think you’ve won?” I sneered.

“You’re just a pawn, Athena. A convenience. Cain will discard you just as easily when he’s done."

Her eyes narrowed, then she cackled.

“Cain loves me! He hadn’t been home for days, right? Because he’s with me every night. Making love to me. He can’t look at you anymore. You’re a bitter, barren hag, Esme. A hen who can’t lay an egg."

Before I could respond, the door to the restroom burst open. Two burly men stormed in. They grabbed my arms, twisting them painfully behind my back.

“What...who are you?!” I struggled, but their grip was like iron.

Athena watched with a smirk.

“Just some friends, Esme. Here to teach you a lesson about respecting your superiors."

The men shoved me against the wall, one of them covering my mouth. I thrashed, my heart pounding, a desperate plea.

Cain! I sent a frantic mind link, pouring all my fear and desperation into it. Help me! Please!

Seconds felt like an eternity. Then, the door was kicked open, and Cain stood there, his eyes blazing. For a fleeting moment, I thought he had come to save me.

“Cain! Thank goodness!” Athena cried, rushing to him, feigning terror.

“She attacked me! She called these men to ruin my reputation! She’s trying to frame me, to make me look bad in front of everyone."

I stared at her, speechless. The audacity. The sheer, venomous manipulation. Cain looked from Athena to me, then back to Athena’s trembling form. His eyes, once filled with concern for me, hardened into disgust. He strode towards me.

“You pathetic, desperate excuse for a Luna!” he snarled, and his open palm connected with my cheek with a sickening crack. My head snapped back, a sharp ringing in my ears. Something broke inside me; my last shred of selfpreservation. I lifted my hand, the pain in my ribs and face fueling a cold fury.

Slap.

The sound echoed through the silent room. Cain’s eyes widened, and his right cheek flared crimson. Before he could react, I hit him again, harder this time, across the other cheek. Then, I walked away, leaving them stunned in shock.

“Esme! You insolent wretch! I’ll make you pay for this!" Cain roared. But I didn’t look back.

I walked out of the auction house, past the murmuring crowd, and hailed a cab.

My fingers trembled as I dialed a number, I hadn’t thought I’d ever use: Elder Marcus of the Whitehorn Pack, the leader of their councils of Elders and uncle to Alpha Kearan, the strongest Alpha in the state.

“Elder Marcus,” I said clearly, despite the tremor in my soul.

“It’s Esme. I’m calling about the offer before."

There was a brief pause before his deep voice rumbled, surprised but satisfied. “Luna Esme,” he said. “I was wondering when you’d come to your senses. Is everything okay?”

“Everything is perfect,” I replied, and a bitter laugh escaped my lips.

“I’ve severed the mate bond. I’ve left him. I need your help with Cain. With my grandmother."

His tone turned serious.

“My private medical team is always prepared. I would have your grandmother transferred beyond Cain’s reach right away”.

A wave of profound relief washed over me.

“Thank you,” I whispered genuinely. “But...there is a condition for this, isn’t it?”

“You remember my nephew, Alpha Kearan?” he asked subtly.

“The one who offered marriage before?” I countered, a hint of apprehension tightening my voice. Kearan was strong, dangerous, a true Alpha, but his intensity had always intimidated me.

“Exactly,” Marcus confirmed.

“He’s still willing to take you as his Luna. Tomorrow. A public declaration, a mating ritual, and signing of the agreement. And in return, we will help strip Cain of everything. He will be nothing. Less than nothing."

My mind raced, the pieces of the puzzle falling into place. Marry Kearan? It was a strategic alliance, but it was also freedom and revenge.

"Done," I said without hesitation.

"Tell Kearan I accept. Prepare everything. Tomorrow, I become the Luna of the Whitehorn Pack. And Cain… Cain will finally pay".

As I spoke, my mind drifted back to when I first met Kearan nine months ago. The annual Alpha’s Summit is a gilded cage of forced smiles and clinking glasses. I stood beside Cain, his arm around my waist, his gaze already straying to the packs across the hall.

Then, silence fell. Alpha Kearan entered, his presence filled with raw power, an untamed grace. His eyes, molten silver, swept the room, pausing, locking onto me. Cain’s grip tightened, a subtle warning, a possessive squeeze. But Kearan strode through the gathered Alphas, cutting a path straight to me. He stopped directly before us, his gaze burning into mine, ignoring Cain completely.

“Mate!” he growled softly.

Cain stiffened beside me.

“She is already mated, Alpha Kearan. To me."

Kearan’s lip curled, his eyes never leaving mine.

"What is your name, my lady?"

“E...Esme,” I whispered.

“Break free, Esme. Stand with me. Be the Luna you were born to be. Not a pawn in another’s game."

My heart pounded. Cain’s hand clamped down on my arm. I looked from Kearan’s burning gaze to Cain’s rigid, furious face.

“I... I cannot,” I whispered.

“My loyalty is to my pack. To Cain."

Kearan leaned closer, disappointment shadowing his eyes, but also a glimmering of understanding.

“Remember this moment, Esme. When he breaks you, truly breaks you, my offer still stands. The Whitehorn Pack will always be your refuge. And when you come to me, Cain, I will make you pay for every tear she sheds."

He turned, a silent command to Marcus, and they walked away, leaving a gaping silence. Cain had pulled me close, whispering reassurances, but the image of Kearan’s resolute eyes haunted me.

“Take me home,” I told the driver, snapping back to the present as I ended the call with Marcus.

I went to our room and grabbed the luggage I’d packed days ago. On the nightstand, the signed severance document lay. I picked it up, a grim satisfaction spreading through me.

I took every gift Cain had given me, every picture we had together, and burned them. The flames consumed the memories, just as he had turned my life to ash. I took a picture of the pyre and posted it on Instagram with the caption, Free at last!

I smiled, admiring the post that garnered comments within seconds. Then, I blocked everyone in the pack, especially Cain and Athena, from my social media accounts. I broke my old SIM card and inserted a new one into my new phone, severing the last digital ties to my past.

Before I left, I made a detour to the kitchen. I found a small, untouched chocolate cake in the cooler. Perfect! I grabbed it and a marker. On the counter, I scribbled a note on the cake box: “Happy freedom, Cain. Don’t worry, you’re invited to my mating ritual." I set it next to a bottle of his favorite whiskey and a copy of the severance document.

With my bag slung over my shoulder, I left the mansion for good, heading to meet Alpha Kearan, ready to prepare for a mating ritual.

By the time Cain found out everything, I had already become someone else's Luna.

And what I have to do next is to make Cain pay a heavy price!
