Winchester at the Pony Express

Isabelle Winchester, better known as Belle, has had some crazy things happen in her life.
After all, her and her older brothers Dean and Sam are the best hunters the world has ever seen.
But when things go awry during a case, Belle finds herself in a predicament.

She has been sent back in time to the Wild West.
With no way home to her brothers.
While she tries to learn to blend in with life style, she discovers that this world and hers are extremely different.
Will she be able to find a way home?
And if she does, will she want to return to a world where monsters exist while leaving her new family behind?
