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."

How Not To Fall For A Dragon
Which is why it was more than a little confusing when a letter arrived with my name already printed on a schedule, a dorm waiting, and classes picked out as if someone knew me better than I knew myself. Everyone knows the Academy, it’s where witches sharpen their spells, shifters master their forms, and every kind of magical creature learns to control their gifts.
Everyone except me.
I don’t even know what I am. No shifting, no magic tricks, nothing. Just a girl surrounded by people who can fly, conjure fire, or heal with a touch. So I sit through classes pretending I belong, and I listen hard for any clue that might tell me what’s hidden in my blood.
The only person more curious than me is Blake Nyvas, tall, golden-eyed, and very much a Dragon. People whisper that he’s dangerous, warn me to keep my distance. But Blake seems determined to solve the mystery of me, and somehow I trust him more than anyone else.
Maybe it’s reckless. Maybe it’s dangerous.
But when everyone else looks at me like I don’t belong, Blake looks at me like I’m a riddle worth solving.
The Alpha Who Hated Me
"Why isn't it working?" he demands.
"Because it's real," I whisper. "Whether you want it or not."
"Then I'll make it clear another way," he says.
He turns to address the entire cafeteria. His voice carries to every corner of the room.
"Let me be perfectly clear," he announces. "She's not my mate. She's not my anything. She's just a sad little girl who needs to learn her place."
The silence that follows is deafening. Hundreds of students stare at me with pity. With disgust. With relief that they're not in my position.
I sit there shaking. My wolf curls up in a corner of my mind and whimpers.
