Alpha Chose Sister-in-Law, I Disappeared

My Alpha mate Derek secretly inherited his sister-in-law Sarah after his brother's death. On the surface, I was his Luna, but in reality, Sarah was the one who truly held his heart. He praised me as the most exceptional Luna, tasking me with caring for all pack members, yet when Sarah tended to an injured male wolf, his jealousy flared so violently that he bit off the poor wolf's paw. In public, he proclaimed me as his beloved Luna to the entire pack, while keeping Sarah hidden safely in the shadows. When enemy wolves kidnapped me after discovering my identity, I desperately reached out through our mind link, begging for help. His response cut deeper than any physical wound: "Olivia, Sarah is carrying my pup. We'll tell everyone it's my brother's son. I must protect her and the baby without leaving her side for even a moment." "Just endure for a few days. Once Sarah's morning sickness improves, I'll lead all our warriors to rescue you." In the days that followed, I sent countless pleas for help through our link, but received nothing in return. Eventually, our connection shattered completely. For an entire year, those wolves imprisoned and tortured me. They broke my hind legs and ripped out my fangs, stripping me of my wolf's dignity. Derek never came for me. When I finally escaped and stumbled back to our territory, blood-soaked and broken, I discovered my daughter locked in the silver prison where rogue wolves were kept. She was being torn apart as food, her small body covered in wounds. Meanwhile, my mate—my pup's father—was joyfully celebrating the first birthday of his and Sarah's pup, announcing that Sarah's child would become the pack's heir. Tears streaming down my face, I gathered my skeletal little pup in my arms. "It’s OK, sweetie. I'll find you a better dad."
