Bad to worse to better

Astra Potter is harry potters twin, she was taken when she was young and doesn't know anything about her family. She was left at an adoption centre.

Sirius black is innocent, Peter went to Azkaban Lily and James are alive and healthy Harry is at Hogwarts and has friends and is happy but what about Astra?

Growing up in foster home after foster home isn't the best experience. Especially when they're abusive, running from home to home not knowing if she will ever be loved, that all changes when she started to show signs of powers?
