Song Of Middle Earth

Hanna in some magical way as she would describe it managed to sing her self into Middle earth. Where now it seems that she can use her song to change things. How will those she meet react on it?
Will she find her reason behind her gifts?

I don't own Lord of the rings or The Hobbit or any of Tolkien works. I only own OC. And those things that not happen in the book. I do this for fun
