Ain't No Rest for the Wicked.

Ottilie Drewitt was a standard girl. She didn't have much money, or many friends, and no family, but she just about got by at school and in life. Well, she did.
One evening, Ottilie falls into a small trap and hits her head. When she wakes up, she's no longer in the 21st century, but rather the 19th. 1899 to be specific.
Now she must survive the classic "wild west" with no knowledge of life there. Maybe she'll find someone to help her get home? Or maybe she'll be trapped there forever? Who knows? Certainly not Ottilie.
