What if Harry had a twin sister named Kathy? Basically follows the plot of the movie, but Hermione and Ron play much bigger parts.
As the movies come out, I'll write stories to them. Will eventually be Harry/Hermione and Ron/Kathy.
Some things about Kathy:
Exact oppsite of Harry. Stubborn, outspoken, rebellious, not afraid of her relatives. Straight, brown hair to her shoulders and brown eyes. Best friends with Hermione, likes Ron. Calls her brother 'Harold' and 'Harry Pothead' to annoy him.
Ch. 3: Kathy and Harry get more letters, and Hagrid comes into the picture.
