A Brief Description and Beginning

With a good life and everything she needed, Aeolus lived a simple party life.
Everyday life was the same and she loathed it. She wished for adventure and romance, like the fantasy stories she read when no one was looking. It was a part of her she loved, creativity and imagination, with sharp wit and cunning thoughts. But that didn't get you anything in this world, but perhaps it did in another.
One day Aeolus falls (literally) into another world, far different than her own. Where her life is actually in danger and where dwarves, elves, and wizards are real.
Finally she finds herself in a world she always wished to be. But when she's taken prisoner by one Elvenking, who knows what will fair for her?
Starts at the beginning of Desolation of Smaug. I go by the movie, not the book.
