Natalie Mcdonald was a Canadian fan of Harry Potter who had a terminal illness, Leukemia. A friend of her mothers wrote to J. K. Rowling, asking if she could write to Natalie. Although Rowling did not receive the letter until after a vacation and feared it was "to late", she wrote back, telling Natalie what would happen to each of the main characters in the series. J.k. Rowling later discovered that Natalie had already passed, but continued to talk with her mother. The two became friends and Natalie was added to the book as a tribute. She was sorted into Gryffindor, the house of bravery.
