The White Knight

18 year old Jessica White is not your average teen. Her dad left her when she was just a baby. Since her dad left, Jessica's mom became an alcoholic. She would spend all of the family's earnings on alcohol. Whenever her mom was home, she would either be yelling at Jess or abusing her.
During all of this, it was her mission to keep her 8 year old sister, Lizzie, safe from all harm. Lizzie was diagnosed with a heart disease right when their mom died from alcoholism. Jessica was determined to play for her sisters treatments. On the way, she meets one boy that changes her entire life.
