In this AU story, Callie is a 13 year old in foster care and a drug runner for a gang. She's tough, less cautious, and often in trouble with the law. Her life intersects with Lena as a teacher at school, and Stef through her encounters with the police. Stef and Lena are a younger couple and have no other children. Disclaimer: Yep, I don't own the Fosters.
