Road to Erebor

Bilbo and Fíriel are hobbits. They both live in a hobbit hole in Bag End. They are siblings. Bilbo is like any other hobbit; likes to party, hates adventures, loves to eat.
Fíriel on the other hand is nothing like that; loves to adventure and doesn't feel like home amongst other hobbits.
One day, a wizard and 14 dwarves cross their path and an adventure begins. Fíriel finds a special someone amongst the dwarves. How will his brother react? What obstacles they'll have to exeed?

I do not own any of the characters, except for Fíriel and Thoriel.
