Rejected by her mate on their twentieth birthday and also being killed by him. That same night, Cleo experienced her wolf, but what she became, even she didn't understand. The next day, she woke up and realized that her mate had completed the bond ritual while she was unconscious, and in that moment she realized that revenge tasted better than him, a revenge that her wolf was more than willing to aid her in.

"Cole is now Neuri's new mate, and that is final!" I suddenly roar from the pit of my gut, growling out my fury in a primal voice unlike any I had ever used before only seeing red. "No wolf is worthy of Neuri, nor anyone else who claims her as their mate is... There is only one man whom she wants, only one man who matters, and that man is him!" 

"What kind of sick joke is this?" Alexander spat, stepping forward.

I turned to face him as my nostril flared, my breathing ragged, and my ears pricked for the slightest movement of his steps towards me.

"You... oh, you..." I whispered, moving my head slightly from left to right as I sized him with my eyes.

"You are my mate, and you will stop this nonsense once and for all." He screamed in my mind.

His voice was carried with force, but beneath it, I tasted fear, and my lips curled upward as I laughed, raising my chin, "Make me."

Not his Luna

Cole POV

As I left Cleo alone in my quarters, her tear-streaked face haunted my thoughts. But I pushed those feelings aside, burying them deep, as I always did. Emotions were a luxury I couldn't afford—not in my position.
