In the Valenti Family, you're born with a chip. It's fused into the bio-watch on your wrist, its digital face counting down every second you have left to live. Everyone could see the numbers ticking down on my twin sister's watch. And on mine. They all knew she would die on our 18th birthday. So Vivian became the untouchable princess of our brutal world. Every diamond-stitched gown was hers. The rarest jewels were hers. Even our father's last shred of humanity was hers. That single sliver of warmth he showed only after his gun was holstered. I used to pity her. Her time was running out. But God, I envied her. She had everything I never did: our parents' love. Then, the night of her 18th birthday party. My parents worried I'd make a scene. That I'd piss off the Don of an allied Family. So they locked me in the cellar. Damp. Cold. While a deadly fever burned through me. I pounded on the heavy oak door, my voice cracking. "Mamma, please! Let me out! I'm burning up. My head is splitting open…" Outside, my mother's voice was a steel trap. "Enough, Sienna! Today is your sister’s 18th birthday. Her last day alive! Stop the theatrics! Can't you suffer in silence for the Family's honor?" "But I'm really sick..." Her footsteps clicked away, fading into nothing. Then the darkness swallowed me whole. And on my wrist, the bio-watch was flashing a critical alert. CRITICAL ALERT: Vital signs mismatch. Paired chip data incompatible. Please verify user.

I was reborn on the night the Alpha lost control to dark magic, his heat spiraling out of his grasp. This time, I didn't become his remedy. Instead, I called his true love—my own sister. In my past life, I fell in love with Nicholas, the Alpha of our pack. When I learned he'd been cursed by ancient dark magic and couldn't control his heat, I made a choice I shouldn't have. I didn't push him away. A month later, I found out I was pregnant. As an Alpha, Nicholas needed an heir. The Council of Elders forced him to hold a marking ceremony with me. On the day of the ceremony, Leah couldn't accept it. She ran from pack territory. Rogue wolves attacked her. Before she died, Leah sent Nicholas ninety-nine distress signals through the mind-link. But Nicholas was in the middle of the marking ceremony—at my request—and never answered. Not once. Afterward, when the pack brought back what was left of Leah's body, his face remained eerily calm. But on the night of our pup's first full moon, he poisoned me with wolfsbane. Before I died, I heard his voice, cold as ice. "If you hadn't gotten pregnant, I wouldn't have been forced to mark you. I wouldn't have missed Leah's call for help. Her death is on you. And you're going to pay for it." When I opened my eyes again, I was back on the night Nicholas fell victim to the curse.
