An-Harry Potter is J.K. Rowling's.

She was beginning to see exactly what the sorting hat had meant, Aura thought; She really did attract trouble, and that would drive any house but Gryffindors insane.
She, Ron, Mia and the twins were on the train, going home for the summer. Well, going with their families, anyway.
The Weasleys were going to visit the oldest Weasley son/brother (Bill) in Egypt. Mia was going to France with her parents, and Aura...well Aura had no idea where her godfather was taking her. She did know that she was going to meet Remus Lupin, a good friend of Sirius and her parents. Sirius warned her that he had a condition that was dangerously contagious once a month.
She laughed as Sirius picked her up and swung her around. The sound had everybody that knew her stopping in their tracks, not that she noticed.
Sirius and her friends recovered quickly (comparatively, anyway) and finished saying/writing their good-byes. After the Weasleys and Grangers had left, Sirius led Aura through the crowds of the station, and out to his car.
"Alright, we're going to meet Remus at the place he choose for the first week of our vacation," Sirius said.
'Which is?'
"You'll see."
