The seventh (and last) edition to the Harry Potter series, Harry Potter and the Deathly Hallows, hasn’t even hit the shelves yet, and it’s already sold more than one million copies. According to Amazon.com, J.K. Rowling’s last Harry novel is the most pre-ordered product in Amazon’s history, with 1.6 million copies already on the pre-order list for shipment around the world. The book will be in bookstores worldwide on July 21, though sales are expected to rise by several hundred thousand copies by that time. Rowling has publicly stated that “at least two” characters will die in this last book, though she refuses to give any hints about who those characters might be. Rowling, with more than 325 million copies of Harry books sold, is the first author to ever make a billion dollars from her literary efforts. The Harry Potter franchise includes a highly successful string of movies, with Harry Potter and the Order of the Phoenix scheduled for theaters July 13. The final movie won’t make it to the theatres until 2010.
