On the day I return to the pack once again, my future mate, Kellan Cohen, throws a fancy banquet for me. My younger sister, Lia Smith, asks me loudly while holding a champagne flute, "Ella, I heard that you were exiled to the wilderness where the lowly inbreds roamed instead of patrolling the borders. Is that true?" Everyone gasps in surprise upon hearing Lia's question. Kellan shoots Lia a glare immediately. If this were to happen a year ago, I would've taught Lia a lesson right there and then.

Not only that, but I also bring up the fact that I want Lia to replace me as a candidate to host the next day's offering ceremony with Kellan. Mom is happy to see me behaving like this. As she pats me on the head, she says, "It seems that Ella finally has learned how to play nice." But Kellan just stares at me with mixed emotions swirling in his eyes. "Didn't you claim that you'd rather die than hand over the position to Lia?" I just sigh quietly on the inside. He's right, but the truth is, I'm about to die.
