The Streets of London

Set in the early 1800s. A girl has been left in front of a decaying orphanage with nothing more than a note that says "It's your turn now".
Now she's fourteen still without a name, excluded from the place that she grew up in, looked down by society. Gossiped about on the streets of London. Nobody to love. No friends. She's grown used to it now. The walls of the Orphanage were her friends the things she talked to. The animals that scurried across the torn down walls were the things she grew to love.
But what happens when she punches a girl in self-defence and is thrown out of the orphanage?
