"You need to know something," said Fili, taking Sara's 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 here with me. I'm going to fight Thorin for the right to make you my Heart Sister. 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.

Of all the wizards in Middle-Earth, Thorin has to deal with a capricious one, namely Gandalf. Determined to reclaim his home in Erebor for his people, Thorin was prepared to accept a hobbit in his company at Gandalf request. But now Gandalf insists that if Thorin wants his help he must allow a woman from another world to join the quest as well. But just because the wizard brings her along doesn't mean Thorin has to welcome or trust her. Who is this woman, why is Mahal's mark on her hand, and why is she here?
