The forgotten sister

Madison Blakely was born December 13th 2007. Exactly 7 minutes after her birth her mother died. A week later her father died, everyone says it was out of grief of losing his wife.Her six brothers hate her for this and are extremely rude to her on a daily basis. Her eldest brother is a part-owner of one of the biggest companies in the world. Madison is best friends with all the owners sons, who happen to be in the grade as her. They have all been friends since they were three. They've helped Madison overcome her guilt of her parents death and have given her a true family.
