The end of the world was upon us, but there weren't enough spots for evacuation. The roars of the zombies echoed in my ears as my fiancé, Oliver, gritted his teeth and pulled me onto the rescue vehicle—securing the last available seat. I arrived safely at the survivor base. Lina, his first love, did not. The zombies tore her apart. Oliver still went through with our marriage, but I never expected that he had only done so to make me suffer. In his eyes, I was the one who had killed Lina. If she had to endure such agony, then I should, too. For five years, he hated me. My life was worse than that of a stray dog scavenging for food on the street. On the day my divorce was finalized, he kidnapped me, dragged me into the wilderness, and wrapped his fingers around my throat. Then, he threw us both into the swarm of the undead. When I opened my eyes again, I was somehow reborn on the day the apocalypse began. The rescue team was shouting impatiently, "One more! We have room for one more—hurry!" I turned to Oliver, watching his hesitation. Then, with a quiet smile, I took a step back and let someone else have the last seat.

From the moment my twin sister set her eyes on Matteo, she decided he was the one. We were just kids, but that didn’t matter to her. In her heart, she believed they were destined to be together. So when their arranged engagement was announced, no one was surprised. At least, that’s what I thought. But lately, something had felt off. Wherever I went, Matteo was there. Lurking in the dark, concealed in the shadows, always watching. I didn’t know what I’d done to capture his attention. I didn’t want it. Yet, I couldn’t stop my heart from trembling like a bare soul caught in the icy grip of winter whenever he came near. Nor could I ignore my body’s traitorous response to his voice, low and laced with wicked intent. I fought to resist him. I truly did. But it was useless. He knew it. And so did I. So I ran. But that was the thing about the Vitales: they always gave chase.

Delilah thought she married the perfect man. Charming. Respectable. Devoted. But then she discovered the man she trusted was a fraud — cheating behind her back, controlling her every move, and secretly stealing from the people who once believed in him. Her marriage wasn’t love. It was a trap. And when she lost the child she was carrying, alone, abandoned, and broken in a cold hospital bed, everything shattered. That’s when he returned. Thorne Weston. The estranged, adopted brother her husband never spoke of. The boy who once made her college life hell — cruel words, wicked smirks and relentless taunts. He's her tormentor. Her shadow. The one who looked at her like he wanted to ruin her… and maybe always did. He disappeared after graduation. Vanished. Forgotten. But now he’s back — colder, richer, and far more dangerous. And he’s watching her. And when she breaks down in the hospital, barely breathing through grief, he corners her in the shadows and makes her an offer that freezes her blood — and sets her body ablaze. “You want revenge? I want you. Be mine… and I’ll destroy him for you.” She should scream. She should hate him. But hate doesn’t explain the fire curling in her belly every time he whispers her name. Hate doesn’t make her knees tremble when he steps too close, smelling of smoke, leather, and sin. And hate isn’t what makes her crave the rough, twisted salvation only he can give. Because Thorne Weston is no longer a cruel boy with a chip on his shoulder. He’s a man forged in violence. Obsessed. Possessive. Unhinged. And he doesn’t just want her — he owns her. Body. Soul. And every shattered piece her husband left behind.
