Mates with an Alpha, Married to a Mafia

Held bound by a promise, Evie kept herself with hopes of being the Alpha's Luna one day, but her fate took a U-turn when her Evil step sister jeopardized her future.
I stared at him with mixed feelings, hesitating for a while, my mind a jumble of different thoughts. But what did I know in this young mind of mine, I wondered.
“Okay, Kieran, I promise.” I blurted out.
“Good, and I promise to also wait for you, not to have any mate and to take you as my mate and the future Luna of the pack when I get back,” he said, raising the leaf to the moon and sealing his words.
My breath hitched a bit as my grip tightened on the leaf. My face curled up in a smile despite the pain that surged through my veins. Just hearing those words gave me hope; I was going to be the Luna of the pack, and finally, everything was going to be okay again, just like it was when my parents were still alive.
