Adventures of a Tenth Roadie

We're all familiar with the tenth walker story, in which a teenager from our world (usually with suitably angsty back story) falls into Middle Earth. But what of the reverse? What happens when a teenager from Middle Earth falls into our world? What sort of quest awaits her? Who will be the other half of her OTP? Another Tommy Ginger/Annafan collaboration. 100% pure crack fic.
