Waterstone's Books announced today that more than 250,000 adults are expected to purchase the adult edition of Harry Potter and the Half-Blood Prince on July 16th alone (exactly two months away from tomorrow), and total sales of the adult edition will likely top all of 2004's adult fiction hits combined.
Debbie Williams of Waterstone's is quoted as saying, "We are amazed by the pre-reservation demand for the adult edition of 'Harry Potter and the Half Blood Prince' at launch. We are likely to see the adult edition of 'Harry Potter and the Half Blood Prince' account for more than 15 percent of launch sales for this book, which means that more adults will be reading a children's book this summer."
