There is an awesomely epic comedy video on YouTube that can be found easily by searching for Catherine Tate David Tennant Comic Relief. It was made for Red Nose Day and stars the actors who play the Tenth Doctor and Donna Noble. This fic is the result of my sister, Mysteryfan17, suggesting that it actually happened in the canonicity of Doctor Who. I hope you enjoy it as much as me!

Lily, a girl left alone with only a letter to guide her, is taken to a world different from her own. Somehow she feels that she belongs there. She is given a chance at a new life with a great adventure right around the corner. Kili/OC.
