My mates an alpha!

"Go emma run!" he yelled as I stood there frozen, I looked towards the rouges running towards me, I just stood there frozen "emma!!" My dad shouted out to me as one of the roughed lunged towards me, I fell to my knees waiting for death to come my way but it never came, I heard a loud growl and something snapping, opened my eyes to come face to face with a black wolf 'mate! It's our mate' my wolf howled in my head, I could smell some type of authority off of him, maybe a beta or the head warrior "alpha Luke! Thank you for saving my daughter" my dad ran up to me and hugged me tightly… wait a minute… MY MATES AN ALPHA!
