The Lady of the Stars

Julia Spade is a normal girl she's got a near eidetic memory, and a teaching job at the local high school. But on her way to her first day she meets the Doctor a man who takes her through all of time and space. A man she met mere moments after him losing his two best friends. These two people who have lost so much find something they can both hold onto. But how long will it last?

Aliens across the depths of the universe and the corners of time are after Julia. They need her for something, something that scares the Doctor as much as Julia for one reason.

He doesn't know why.
