Today’s Strong Female  is Tiffany Aching of the Discworld series by Terry Pratchett, starting with The Wee Free Men.
Why is she strong?
She is not intimidated by title, as she can relatively easily speak with Nanny Ogg. She takes no guff from the local Wee Free Men. She will defend her family and land when it is necessary. 
Keep it civil people.
 10 of these already! Can you believe it?
 I’m being deliberately vague here because the series of books featuring Aching is quite good and I’ve only read the first two. Most of the books should be available in your local library so go check it out.
