Sea-Green Eyes

What if Sirius Black and James Potter each had a sister? Of course, the two girls are best friends. When Harry turns six, Em (Sirius' sister) realises that Harry has been abused by the Dursleys. She won't stand for this and claims her guardianship.

I do not own the HP characters, J.K. Rowling does.
