Sophie's Sister (Mamma Mia x Harry Potter Marauders Era fanfic)

A/N

Just so you know, I won't have who's POV it is in, in different fonts I will be putting a picture of who it is at the top like in this A/N I have a drawing of a girl! Peter is NOT a traitor, and Isabella knows about magic and so does lots of people on the island. On the next page I will post who I imagine as the characters. I DON'T OWN CHARACTERS EXCEPT FOR MY OC/ISABELLA! And the people from the Marauders Era share the same belief's as people on the island (about Greek Gods and Goddesses).
