Mated to Ex’s Brother After His Betrayal

"On the day of my mating ceremony with my Alpha mate, Derek, his childhood sweetheart Victoria returned.Victoria, using her supposed silver poisoning as an excuse for needing care, crashed our ceremony. She snatched my mate away, turning me into a laughingstock for the entire pack.Derek, seemingly unconcerned, said, "She's silver-poisoned. Her body's weak. Don't overthink it."He carried her to the pack healer, leaving me alone and humiliated.I yanked off the silver pendant he'd given me when he chose me as his mate. As I tossed it aside, it sliced my palm. To my horror, the small cut didn't heal. Instead, blood flowed freely.Because I was the one truly poisoned by silver.Derek didn't know. Months ago, during a rogue wolf attack, I'd taken a silver bullet meant for him. I survived, but my wolf lost her healing ability forever.Later, I overheard the usually strong and calm Alpha yelling at the pack healer, "How did you miss this? If anything happens to my Luna, none of you will survive!""
