The Undecided Title of Sara Miller (Hobbit Fanfiction) (Thorin/OC)

"You need to know something," said Fili, taking her face in his large warm hands. "You will always have me. Even if the Valar take you away tomorrow, I will always be your brother. I want you. I'm going to fight Thorin for you, but even if I lose, you are always my sister. I would sooner stop being a dwarf than stop being your brother." Can exploring caves land you in a hobbit's pantry? It happened to Sara Miller. Taken from the 21st century, she must navigate through middle-earth to find a way back home. But to do so she will have to understand why the Valar have sent her in the first place, something even Gandalf does not know. All Sara wants to do is return home so she can resume the search for her family but now she is stuck going on this insane quest. Why are wizard's so capricious? Thorin has first-hand experience with one, namely Gandalf. Thorin is determined to reclaim his home in Erebor for his people and was even prepared to accept a hobbit on the quest. But now Gandalf insists that if he wants his help he must allow a woman from another world into his company as well. But just because the wizard brings her along doesn't mean Thorin has to play nice. Who is this woman anyhow and why is Mahal's mark on her hand?
