What Is The Experiment?

The Potter Experiment is something I concocted to improve my own writing. Breaking down a successful book is one of the best ways to become a better writer (other than actually writing, which is pretty important too). J.K. Rowling landed herself squarely in children's literature history when she published Harry Potter and the Sorcerer's Stone. I want to know how she did it. That's what The Potter Experiment is about. 

SPOILER ALERT Of course to discuss a book, it's assumed that the reader has already read the book.
