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 Found the Babies
"When..." He growled in my ear, "When we will be getting married, I will be your only king, do you get my point? Only one queen, no misters or mistresses. Just me, just you, and yeah, our babies."
I shivered.
Alyssa Reynolds found herself in a situation, while returning home from work, and she had three choices:
Simply walk away and forget that you ever heard the sound of wailing infants.
Call the police and inform them about the innocent wails.
Follow the sounds of the wails and take the matter in your hands, deciding what to do later.
Being a kindhearted soul and a sucker for babies, she found herself choosing the third option, finding the two little lives.
Two little lives that changed her whole life, her love life included. Her life now revolved around the babies as diapers, vomit and shit seemed to surround her.
Just when she thought that now it's just her and the babies, her whole world flipped over and she found herself living under the same roof as the egotistical, obnoxious and hot-as-hell Terence Powers, the business tycoon who was not going to let the woman fend off for herself and the babies alone.

What the Heart Wants (Book 1 of the Alpha Faros Series)
Not loving him will cost more.
Derek has one goal: survive high school without drawing too much attention or pissing off his pack’s alpha.
As the youngest son of the alpha, his life is governed by lycan hierarchy, tradition, and politics. With no signs of awakening a lycan spirit, his only value is what he can do for the pack’s image. He knows he’s only ever one misstep away from exile… or worse.
Then, he finds a boy trapped in a locker on orientation day, and everything changes.
Derek shouldn’t want Nikolias. He’s off-limits. A risk Derek can’t afford.
So why does it feel like he’s the only thing worth fighting for?
Nikolias has just lost everything: his parents, his home, and any sense of peace. Sent back to the town his family left years ago to live with his prejudiced and controlling uncle, who wants nothing to do with anything—or anyone—not human, he’s trying to do everything in his power to get out quickly.
But then he meets Derek again, and all of his plans vanish in the soft, yearning flecks of gold in Derek’s green-hazel eyes. He’s drawn to Derek in a way that’s impossible to deny, and he thinks Derek feels the same way, despite the danger their relationship holds for him.
As Moonshadow's politics turn deadly, Derek and Nikolai are caught in the crossfire of a war that had started long before they were born, and their bond becomes a threat and a lifeline that neither can afford to sever.
Because the heart wants what it wants….
And it never asks permission.

Ruined : You will always be mine.
“Fuckkk”, I couldn’t help but scream.
“You need to learn to be obedient” he said as he kept thrusting into me. When I felt his hands on my clit my body shook.
“Asher please, it’s too much”.
“No. if I really wanted to punish you, I would give you all of me”, he said against my ears and my entire body froze. Suddenly he moved and I was standing again. This man was insane.
I felt him behind me. “Ten Lashes for your disobedience”, he said
“Asher please”,
“No”. His voice was cold and void of any emotion.
Asher was what I wanted , what I truly craved until it was too late. An orphan should never fall in love with someone out of their reach. I thought loving him was the right thing to do until he revealed his true identity and Ruined me. I was ruined for everyone one else .

The Sterling's were the most powerful in Havenwood and Dorian Sterling was off limits.

To protect what’s mine
Vengeance of the Forsaken Luna
"Bella." Ethan's tone shifted, taking on that warning edge I knew too well. "Faye is vulnerable right now. She's terrified you'll resent her, that this will divide the pack. The last thing she wants is for this baby to come between us."
"Then you shouldn't have done it." I met his eyes squarely, letting him see the ice in mine. "Go back to your son."
"For fuck's sake." He dragged a hand through his hair. "How many times—it was artificial insemination. They used my sperm, yes, but Faye and I never—"
Bella let out a cold snort. Such brazen lies. Her mate had an affair with his brother's partner, and his entire family helped force her out with nothing, all to make way for the mistress to take her rightful position. Poor fool—he thought she was just an unwanted adopted daughter, easy to dismiss and control. He never knew the computer genius he'd been searching for was his own Luna.
Since he'd tainted himself, Bella was done. She rejected him and reclaimed what was hers, rising to the top with help from Victor, who'd been secretly in love with her for years.
When Ethan tried winning her back: "You don't want our child growing up fatherless."
Bella smiled mockingly. "The child's father isn't you."

**
I hate girls like her.
Entitled.
Delicate.
And still—
Still.
The image of her standing in the doorway, clutching her cardigan tighter around her narrow shoulders, trying to smile through the awkwardness, won’t leave me.
Neither does the memory of Tyler. Leaving her here without a second thought.
I shouldn’t care.
I don’t care.
It’s not my problem if Tyler’s an idiot.
It’s not my business if some spoiled little princess has to walk home in the dark.
I’m not here to rescue anyone.
Especially not her.
Especially not someone like her.
She’s not my problem.
And I’ll make damn sure she never becomes one.
But when my eyes fell on her lips, I wanted her to be mine.
Underwater: The Silent Luna
It sounded like fate. Like rescue. Like the moment the universe finally chose her.

The Alpha never asked for her. Never wanted her. Luna Amber arranged everything without his consent, driven by selfish motives Meadow couldn’t see until it was too late. What should have been tender and sacred becomes a cage, and Meadow is trapped in a nightmare she can’t wake from.

Even worse was overhearing Darrell laugh to his friends: "She's useful—obedient, doesn't cause trouble, handles housework, and I can fuck her whenever I need relief. She's basically a live-in maid with benefits." He made crude thrusting gestures, sending his friends into laughter.
In despair, Sable left, reclaimed her true identity, and married her childhood neighbor—Lycan King Caelan, nine years her senior and her fated mate. Now Darrell desperately tries to win her back. How will her revenge unfold?
From substitute to queen—her revenge has just begun!

Females are claimed. Controlled. Bred.

The moment they claim her, war ignites.
Alex refuses to submit to their bond, their authority, or the dangerous pull between them. She fights every command, every touch, every instinct threatening to drag her under. But the more she resists, the more obsessed the brothers become.

The Contract Wife: Marriage Of Malice
He didn't finish. He didn't need to.
I didn't tell him to stop.
Instead, my fingers curled into his shirt, clutching the fabric as though it was my only anchor. Something in him snapped—something he had been holding back for too long. His mouth found mine in a kiss that wasn't tender, but hungry, desperate.
I gasped into him, his hand sliding up to cup my jaw, holding me as if afraid I might vanish.
"You drive me insane," he breathed against my mouth, his lips trailing to my throat. "I can't lose you, Ella. Not you."
My head fell back, a soft sound escaping me as his fingers memorized my waist. My anger melted beneath his desperation.
"James..." I whispered, more plea than protest.
His hand caught mine, fingers threading together tightly. "I'll bring him back. I swear it. Just... don't turn away from me. Please."
The word please—low, ragged, almost broken—undid me more than anything else could have.
Ella never imagined she would marry the man she had secretly loved for years in such a way.
When her brother Theo faced twenty-five years in prison for massive embezzlement, the ruthless business tycoon James Lancaster offered her a deal: marry him in exchange for her brother's freedom.
This wasn't a fairy tale proposal, but a carefully orchestrated revenge. Because in James's heart, Ella was the culprit who had killed his sister Cecilia. He wanted her to pay the price—to atone with a lifetime of suffering.
COLD (Ruthless Player)
“Please… Nick, wait.” He pulled out, thrusted back in. “How much? Twenty thousand? Fifty? Hundred?” With every question, he thrust harder and harder. My neurons are frying with the confusing feeling in my brain. Torn between pleasure, fear, and panic. I couldn't utter a single sentence to save my life.
His cold eyes pinned me in place while he plundered my body with deep thrusts, which only added to my confusion. My dumb body mistook the mixed signals, my pussy becoming even wetter than before.
“I hope she'd paid you well, because I'm going to fuck you all night long, hard,” he growled. “Sleep, then do it all over again. I want to feel you come for me, Andrea, want to feel you squeeze my cock, milking me.
Begging for me to give you the high only I can, I'm going to fucked you until I fuck all my wife's money's worth, I want you to remember how hard I took you while you're meeting her.” I sobbed, moaned, and tried to scramble out under him.
“No, please…Nick, let….let me explain.” Nick abruptly pulled out. His eyes were cold but hooded.
Andrea was sent to take down billionaire magnate Nicklaus Montgomery.
Her mission was simple: get close, seduce him, find the proof, and disappear. Instead Andrea finds herself exposed—cornered into signing a contract that binds her to Nicklaus's side as his lover. Now she’s living in his world of wealth, danger, and secrets… and the deeper she falls into his bed, the harder it becomes to remember what side she's on.
