Interesting and different. I like it.

Loving this. Can't wait for more.

Okay, I admit, I thought it was Fili and Kili at first because that's normally how a bunch of these stories start. You get points for originality, so yay for that! Also points for correct grammar and spelling, not revealing what the tattoo was, and not having her name revealed. I'll have to take away minor points though for the Mary Sue-ish "leave behind a sad pathetic life for one of excitement and adventure". So I'll give you... a 7/10, with room for improvement!

Though question. How is she unable to use ink to converse? Is it because she'd write in English and no one would be able to read it? Or would the ink like shift and move like an enchanted object until it looks like a bunch of squiggles?

I like the OC already! She needs a hug right now. But did we get her name? Since its first person, I don't recall. Wait, how will anyone know her name? Do they have to nickname her? That's kind of cute lol

Like you totally had me going when she was approaching the fire, like "Oh, they'll be friendly faces and singing. It'll be lovely." Nope! Oh man, I'm glad she got away!

I wonder does her "curse" include screaming as well? Like, could she yell for help on the rock if she doesn't use words? I like how it's specified that it'll break once the goal is reached- how cute will that be when she can finally speak.

Wow, I really liked how you handled her "divine intervention". It'd be interesting if any of the Valar appear to her later on. Was that Yavanna, she met? Maybe it'll be revealed later on.

Really great start to the story. Your writing style just flows so well. Awesome first chapter! I need to know what happens next!
