Rejected And Abused Luna

My life wasn't always this miserable, I had a happy life going, and both biological parents were happily married and in love until my mother got very sick and she ended up passing away with lung cancer. And then my father remarried to my evil stepmother, who became the new Luna of my father's pack. She already had two children, her son Rex, and her daughter Jessica Himson both like to abuse me mentally and verbally sometimes even physically. And with me being the only child of the Alpha, I'm supposed to be the next Alpha of my father's pack, but my Stepmom wants it to be traditional and allowing her son to be the Alpha of my father's pack because in her head a lady should not do a man's job and leading a pack herself. But that's not it all , traditionally, an oldest child of the Alpha has to take responsibility to be the next heir to rule the pack. And just when things got worse, a new enemy steps foot into our territory.
