Enchanted

Faith Carr is a completely normal girl. Until she has to do a family tree project and realizes she doesn't have any similar physical traits to her family.
She learns she is adopted.
She learns she is not a human.
She learns her neighbor is a witch.
She learns that her creepy neighbor is her mom.
Faith sets out on an adventure to reverse herself, so she can go back to being an unsuspecting human.
And on that journey, she learns being a witch is much more than just casting spells.
