A Father's Daughter

Leia Skywalker -mostly known as Princess Leia Organa -has a big challenge ahead. The Force chooses her as the one who has to save Anakin Skywalker, her father, from the Dark Side and becoming the villain Darth Vader.
She wonders why the Force didn't choose Luke, her brother for this important mission, because of his better relation with their father.
But maybe this is a new opportunity to improve their father/daughter relationship.
