Harry and his Sister

Harry Potter was a young man who, in his father's and his opinion, had a lot going for him. He was the youngest Seeker for a Hogwarts Quidditch Team in a century. He was wealthy, an heir to a Lordship, and got great marks in school.

A Seeker was usually a girl's position since a petite figure was preferable. At four eight, Harry was smaller than some First Years. The divorce settlement had dropped the Potter wealth to several million less than the Malfoys. The Potter Lordship was at best a ceremonial holdover after their support of Dumbledore saw the Potters stripped of many old honours and rights. And yes he got good marks. Not all his delusions are inaccurate, just most.

He was looking for a specific person. His sister. He'd been hit with the nutpunch jinx many times for calling her that, but she was the daughter of his father's Wife. Ex-Wife. They were raised as siblings. For a few years. And he had been told about what was happening his year. The TriWizard Tournament. He was going to be a Champion and reunite his family. He didn't care that his sister wanted nothing to do with him, she would finally respect him and his father when she saw him holding the Trophy above his head.

Where was she?
