I stared down at the contract, a wave of defiance bubbling up in me. I turned back to him, meeting his gaze head-on. "I never asked for your help," I said, "I would've found a way to save my mother on my own. You may think you own me, but I'd rather die than marry you." A slow smile crept across his face, a smug, knowing look that sent a chill down my spine. He knew exactly what I was thinking, as if my resistance only entertained him. "Look at me," he commanded. I reluctantly turned back, locking eyes with him. His face had shifted, his expression darkened, and for the first time, true fury was etched in his eyes. "I’ll count to ten," he said, "If that contract isn’t signed by the time I reach ten, I’ll make the same call I made to pay those bills. Only this time, the instructions will be different. Your mother... your sister…they’ll both be gone." He took a breath, settling back as if the threat were a mere matter of routine. "So… ONE!!" I swallowed hard, my heartbeat pounding in my ears. Could he be bluffing? No, I'd seen him kill before, seen how casually he turned life and death into sports. "FOUR," he counted. My hands started to shake. What could I do? If I signed, I'd be bound to him forever, trapped as his wife. But if I didn’t... my mother and sister’s lives hung in the balance. "SEVEN." I closed my eyes, fighting the panic rising in my chest. He wouldn’t do it, I told myself. He couldn’t be that monstrous. But even as I thought it, the doubt crept in. I wasn’t sure. Then, he hit "TEN" himself

His steely gaze bore into mine, an abyss of emotionless darkness. "Marc-" "SHUT UP!" I flinched, a shudder coursing through me. He came on closer, his fingers tightening around my neck, a cruel parody of a caress. I met his frightening stare, I stared at him breathing heavily. "Just be still." I lowered my face, eyelids fluttering shut, as if seeking solace in the darkness. "I own you." His declaration resounding heavy in the air, an unbreakable chain binding me to this desire’s. In that moment, I knew - there was no escaping the clutches of this man who held me captive, body and soul. **************** In the heart of a city shrouded in shadows and secrets, Elena Santiago's life takes a dangerous plunge.

In the Kingdom of Avelune, no one dies without warning. Every soul is born beneath a glowing number, counting down the exact day death will come. Elara Veyne has no number at all. She's spent her life feared for it, until she locks eyes with a stranger in the rain who shouldn't be standing at all. His number reads zero. He's breathing anyway. And when he looks at her, it isn't with fear. It's with recognition. His name is Kael Draven.

Stopping it might mean losing the one person who has never let her go.
