I remain rooted to the spot in the corridor. Suddenly, the weight of the gifts in my arms feels extremely heavy. Natalia is the only child in her family.

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.

On my wedding day, my arranged fiancé abandoned me and chose my sister instead. As I became the laughingstock of every elite guest in attendance, my business partner James Crawford shocked everyone by publicly proposing to me with a passionate declaration of love. After we married, he was incredibly attentive, especially during my pregnancy when he catered to my every need. I thought my suffering had finally ended. Until I overheard his confession to my sister: "I've only ever loved you." James's voice carried a passion I'd never heard him use with me. "Marry her? I was only after her resources, connections, and her talent for making money. She's nothing but a useful cash cow." "Now that she's pregnant, even better." His tone was coldly calculating. "With the baby, she'll be even more dependent on me, more devoted. She'll never leave." Everything I had treasured—our love, our marriage—was all a lie. Learning the truth, I turned and walked away without a word. I was done with this charade. Everything that belonged to me, I would reclaim with my own hands.
