In the Flames (Harry Potter Fanfiction) Marauder's Era

Avia was abandoned in a park with only a blanket and a name. Walburga Black found her and took her in, planning to have Avia and her son, Sirius, married. But when they go to Hogwarts, Avia finds that she no longer knows how she feels. What if there is someone out there who's better for her? When she finds out that she is more than she'd ever thought, how would she react? When she finds that she has powers, greater powers than any other wizard or witch had, will she lose herself or become stronger? Avia finds that sometimes, you have to be your own savior to truly survive.
