This idea popped into my head and I just had to write it.
Disclaimer: I don't own Harry Potter or any of the canon characters.
Hazel Pond had always been, in the simplest of terms, a good girl. She excelled in school, helped out with chores at home, prayed every night, and went to church every Sunday at the Holy Trinity. She volunteered at a long-term care residence, reading the bible to mostly blind old men and women.
Her parents simply adored her; she was their little angel. She was well-known in their small town of Barnes as a very sweet and thoughtful girl. She was known well in the Holy Trinity for her beautiful singing voice, which she often lent to the church choir.
She was, all around, a very good girl who had only rarely upset her parents or those around her. She loved deeply and was loved in return, despite the fact that strange things had a way of happening when Hazel was around. Very strange things, such as the cat hanging from the chandelier or the piano playing of its own accord while Hazel merely stroked the keys in longing. She did not know how to play– which her parents did not realise, thinking her to be the source of the beautiful music that often filled the house. Hazel had never questioned these strange occurrences; she was used to them. Her parents dismissed them and did not connect them to their perfect Christian daughter.
Needless to say, this all would change; if it did not, there would be no story.
This change occurred on her eleventh birthday.
