Two princesses, Elizabeth and Margaret, sharing their lives as equals. Blissfully unaware of the decision their uncle would make that would set a new course for them both, and change the entire shape of British history. Despite the enormously close bond they had in their formative years, the heir to the throne and her younger sister would face very difficult challenges which would come to define their relationship. The eldest sister would grow up to become the most powerful woman in the world, and the titled leader of the British Empire. Her sister, Princess Margaret would struggle to find meaning and purpose to her role, sometimes driving a wedge between the two sisters. Margaret had a magical charisma, lighting up the room and captivating those in her path. Yet, Elizabeth’s exceptional dedication and attitude to the duties she inherited, as she followed in her father’s footsteps, would have the nation’s unwavering respect and love. A love which Margaret would come to envy. They were both Princesses, but only one could be Queen.
