The twin of Lily Evans

Sage had always grown up in the shadow of her twin, Lily. Both of them had been accepted to Hogwarts and Beauxbatons,but they're parents decided it was best that Lily went to Hogwarts whilst Sage went to the French academy of magic, but that all changed in her last year...
At sixteen she moves back home, much to Lily's distaste and Petunia's excitement.
Is she ready to take on her Hogwarts?

sry, i SUCK at intros, BIG TIME.
