Introduction
I woke up reborn on the night they buried him.
Standing in that funeral chamber, watching the lawyer crack open the sealed will, I discovered I could suddenly hear thoughts. My sister Vivienne's voice ripped through my head: Not marrying that butcher. No way in hell.
She lunged forward and grabbed Adrian—the refined bastard son who looked like a lawyer instead of a mobster. The same "perfect gentleman" I married in my past life.
Which left me with Dominic Callahan. The scarred heir. The Executioner.
Last time around, Vivienne married Dominic and got beaten down for years. I married Adrian and lived like a queen.
I almost laughed out loud.
Because she has no idea—this time, she's the one who grabbed the monster.
Chapter 1
Cass's POV
I wake up reborn on the night they bury my father.
In the underground chamber, two candles flicker beside his portrait. The lawyer cracks open the sealed will and starts reading out the debt: my father owed the Callahan family a life. His two daughters have to repay it through marriage.
Two men stand at the far end of the room.
One is Dominic Callahan, the eldest son—the family's "Cleaner." He's got a scar running from his brow down to his jaw. People call him the Executioner.
The other is Adrian Callahan, the bastard son. He's in a nice suit with this gentle smile plastered on his face. Looks more like a lawyer than a mobster.
Not marrying that butcher this time. No way in hell.
A voice rips through my head.
I spin toward Vivienne. Her mouth is shut, but that voice is definitely hers. My heart slams against my ribs as I stare at her—can I actually hear what people are thinking?
Adrian's the smart choice. Refined, cultured. I just need to grab him before she does.
There it is again. Everything clicks into place. I'm not just back from the dead—I can read minds now. And from what she's thinking, she's been reborn too.
The second the lawyer finishes, Vivienne jumps in. "I choose Adrian."
She walks straight to him and pulls out the ceremonial dagger from her waist. The blade cuts across her palm, blood pooling in her hand, and she doesn't even flinch as she grabs Adrian's hand. Their blood mixes. The pact seals.
The lawyer turns to me. "Then you'll marry Dominic Callahan. Miss Cassandra Hayes."
Vivienne's eyes light up with victory. Your turn to suffer now, little sister.
In my past life, Vivienne married Dominic.
That man was cold as stone. Never brought her to family business, never let her in. Every time she tried getting close, she got punished for "breaking family rules"—whippings, lockdowns, stripped of everything. Five years in, she still hadn't given him an heir, so Dominic's mother kicked her out herself and took away the Callahan name.
I married Adrian. He was perfect—thoughtful, sweet, took me to fancy parties, bought me cars and jewelry, kept me away from all the violence. Everyone said I'd gotten lucky.
Then Dominic died in a gang shootout. Adrian took over the family, and overnight I became the queen of the underworld.
Vivienne lost her mind with jealousy. Staged a car accident while I was out. Killed us both.
I take the dagger and walk over to Dominic. The blade stings when it cuts into my skin, but my hand stays steady.
When I grip his hand, I try reading his thoughts—nothing. His mind's completely silent, like there's nobody home.
But when Adrian looks at Vivienne, I catch what he's thinking.
Sweet little doe. Bet she cries pretty.
My breath stops for a second. I'm staring at that gentle face of his.
Whatever's hiding under that smile reminds me of things from my last life I'd rather forget.
The lawyer clears his throat. "Please complete the blood oath."
I snap out of it and glance at Dominic next to me. He's just waiting, expression blank, that scar looking even nastier in the candlelight.
But somehow, standing beside him feels safer. At least with him, the danger's right there on the surface.
This time, I'm changing how this ends. I'm making it out alive on my own terms.
Three days after the blood oath, we have to show up to dinner. Family rules.
It's at the Callahan family's private club.
Adrian pulls up in a silver sports car to get Vivienne, and right at the club entrance he drapes this expensive-looking fur coat over her shoulders.
He walks into the hall with her on his arm, showing her off to everyone. "This is my fiancée. I'd die for her."
Everyone eats it up.
"The second son's such a gentleman."
"He treats her so well."
Meanwhile, I'm sitting alone in whatever basic car the family sent, staring out at the neon lights.
When I walk into the hall, maybe three low-level guys bother saying hi. Dominic's nowhere to be seen.
I can hear every thought around me crystal clear.
Poor girl, marrying the Executioner. She's done.
He didn't even show up tonight. Dominic obviously doesn't give a damn about this marriage.
She'll end up in the punishment room soon enough.
Vivienne strolls over in that fur coat, sweet smile on her face.
"Look how good he is to me." She makes sure I see the jeweled buttons up close.
Then she lowers her voice, all fake concern. "So where's Mr. Dominic? Don't see him anywhere."

I Loved You in Silence, You Betrayed Me in French
At my birthday party, my husband whispered to his mistress in French that he missed her. His voice was low, but I heard it all—the black lingerie, the bit about how pregnancy makes you more sensitive. His French clients around us were laughing. He turned and put his arm around me, claiming he was just helping his clients come up with sweet nothings.
He doesn't know I understand every single word. Just like he doesn't know that inside my body, I'm carrying his other surprise. And his mistress—she's pregnant too. Two wombs, one secret.
Confrontation would be too cheap. Tears are worthless. I quietly started cataloging the hidden networks my father left behind, activating the Swiss accounts.
In seven days, Zoey Smith will cease to exist. And what will my husband's reaction be?
He Never Loved Me, Until I Left
I put away the divorce agreement with a wry smile.

My six-year-old son looked coldly at his biological father and said, "Get lost, you bad uncle! You don't deserve to be my dad!"
When I Disappeared, He Regretted It
The moment the screen lit up, my entire world came crashing down.
The woman on the bed was Calista - that girl who grew up with us since we were kids. And that hand caressing her skin was wearing the wedding ring I had personally put on Matteo's finger.
"I've missed you so much..."
"You drive me crazy, baby..."
Those sweet words I knew so well completely destroyed me.
Everyone said we were the perfect couple, but who knew this marriage was built on nothing but lies?
Since he's so good at acting, I guess it's time I gave him a show of my own. I'm going to make sure everyone sees what this "perfect husband" really is...
He Thought I'd Never Leave
When he said he was being bullied, I believed him. When he kissed me on that rooftop, I thought he felt the same. When he asked me to transfer schools with him, I said yes without hesitation.
Then I heard him bragging to his friends: "She'd save her first time for me. Hell, she'd still be thinking of me on her wedding night."
The bullying was staged. The kiss meant nothing. He just wanted me gone—so his new girl could feel more comfortable.
He thought I'd beg. He thought I'd cry. He thought I'd never actually leave.
I left the country.
And ran straight into his stepbrother.
I Died While They Threw Her a Party
Their real daughter came home. She'd only been back two years. That's all it took to erase twenty-four.
When kidnappers grabbed us, I used my body as a shield. They beat me until something inside me ruptured. I was dying from internal bleeding, but no one could tell.
My parents wouldn't even look at me. "This is your fault! None of this would've happened if it weren't for you!"
"Get downstairs and apologize to your sister. If you can't, pack your things and get out."
They threw her a party at a downtown hotel while I died alone in my room.
I thought they'd be relieved. Maybe even glad. I thought they'd just move on like I never existed.
But when they finally learned the truth, they fell apart.
Bury Me in His Regret
The kidnapper pressed the gun to my temple and asked, "Choose your wife or your sister-in-law?"
Zachary didn't hesitate. "Let Valerie go," he said.
He actually chose to save his sister-in-law! In that moment, even the baby in my belly seemed to stop kicking.
Later, they locked me in the basement. Drugs to delay labor were pumped into my veins over and over. Zachary wanted to save the "firstborn son" status for his sister-in-law's child.
When warm blood finally soaked through my skirt, I dialed the number I knew by heart with shaking hands.
"Zachary," I whispered into the phone, "our child... can't wait any longer."
The Kidney That Killed Me
A few months ago, my sister was hospitalized with kidney failure. The doctor said she needed a transplant. My family's first thought was me—the backup daughter they'd kept around all these years.
When my husband Allen took my hand with tears in his eyes and said, "Only you can save her," I agreed without hesitation.
When the doctor explained the surgical risks and potential complications, I smiled and nodded my understanding.
My parents said I'd finally learned what sisterly love meant.
Even Allen, who'd always been cold to me, held my hand gently and said, "The surgery's safe. You're so healthy, nothing will go wrong. When you recover, I'll take you to Hawaii."
But they don't know that no matter how the surgery goes, I won't be around to celebrate.
Because I just got my own test results—I have terminal brain cancer. I'm going to die anyway.

George remained unconcerned, convinced I would never leave him.
His deceptions continued until the day the divorce was finalized. I threw the papers in his face: "George Capulet, from this moment on, get out of my life!"
Only then did panic flood his eyes as he begged me to stay.
When his calls bombarded my phone later that night, it wasn't me who answered, but my new boyfriend Julian.
"Don't you know," Julian chuckled into the receiver, "that a proper ex-boyfriend should be as quiet as the dead?"
George seethed through gritted teeth: "Put her on the phone!"
"I'm afraid that's impossible."
Julian dropped a gentle kiss on my sleeping form nestled against him. "She's exhausted. She just fell asleep."
