Caleb's Sister?

Looking for a fic that was told basically from the point of view of Caleb's sister?  She had a southern accent...
He always told her about the Winchester boys and how Sam would be a better fit for her than Dean (or something to that effect).
She goes looking for the brothers and I think she maybe finds Sam?

Totally vague, I know, but you've helped me find stories with less.

I will love you forever.
