The unwanted daughter

Her family has never liked her. Her Father is the head of the American Mafia and her Mother's Father was the head of the Spanish Mafia. Her Mother's parents are now dead and her Uncle is in charge of the Spanish Mafia. She has eight older brothers. Her oldest brother Xander will one day take over the Mafia. The youngest of her 8 brothers is 5 years older than her. Then she has a twin who is older by about 15 minutes. She and her twin have little in common. Her twin is a girly girl, hates to get in trouble and strives to be the perfect Mafia Princess. She, on the other hand, is a tomboy, gets in endless trouble and hates the idea of being a Mafia Princess. Her Mother and Father have an arranged marriage and she has no intention of doing the same. Her twin never seems to even question the idea. Still her family assumes she will one day marry to benefit the American Mafia. She has been told her whole life that this is her duty. They have no idea that her plan is to leave as soon as she turns 18.

Her Mother wanted a girl each pregnancy and was ecstatic when it finally happened. She was fine with it being 2 girls until she found out her youngest daughter had no interest in clothes and dressing up so she could impress her friends. Her husband relegated all the responsibilities of both girls to her. Preferring to see his little girls well mannered at dinner. Whenever he was home, dinner was a family affair, and he expected all 10 of his children to attend unless being disciplined. Which was common with having 8 rowdy boys. Still when present his son's behaved themselves outwardly and had inside jokes with each other inwardly. Not their little sisters tho. They believed they were Mafia Princesses and should act accordingly. When they did not they left it up to their Mother to teach them.
