He's the Chosen one (Harry Potter)

Nia Lestrange. Cousin to Draco Malfoy.
She's everything Evil and worse. She was raised to hate everyone and everything that isn't pureblooded.
When she's forced to transfer to Hogwarts from Beauxbaton's going into her 5th year, she meets Harry Potter in Defense against the dark arts class.
There's something changing in the young girls heart, when she and Harry are forced to attend detentions together after she defends him once on the first day of school, resulting in torture at the hands of Voldemort himself.
She becomes more reckless than every and even helps the Weasley twins once or twice throughout the year, however when her family and Voldemort discover she's become somewhat attached to Harry Potter. She receives the worst torture of anyone in wizarding history and stays in Malfoy Manor after it. It's not until Harry discovers her true nature that he finally cracks open the mystery of Nia Rosalina Lestrange.
