The Muggleborn.

Lorena Hevglow. a Muggleborn. She grew up without knowing any of the wizarding world, that is until she got her Hogwarts letter and met a certain greasy haired professor.

Once at Hogwarts she found out not only was she a witch but her best friend was a wizard.

They had a few journeys together and it just brought them closer. Lorena was a smart girl and so she got an inheritance test done.

(I don't own Harry Potter just Lorena. This book will start from prisoner of azkaban.)
