I've decided I'm gonna write a seven book series. The MC is Harriet Snotter, who is orphaned by th evil Lord Moldy Wart. She lives, as a child, with her horrible family, Uncle Monticello and Aunt Pansy, and Cousin Pudley. And a giant comes in and she is told that she is a witch and will be going to Oinkwrinkles Academy of Magic and Advertising.
And in then end, she must confront Lord Moldy Wart who wants the Magician's Rock, which will make him immortal, the Magician's Rock being made by the Alchemist Jonathan Purtell.
We love you, JKR!
