Already Number One

The sixth book in the Harry Potter series is already number one in sales - even though it won't be released until July 16. Just a day after the announcement that Harry Potter And The Half- Blood Prince will hit bookstores in both America and Britain in the summer, the latest installment in the teen wizard series is already at the top spot on the Amazon.com list in both the USA and the UK.

To date, the Harry Potter titles have sold 250 million copies worldwide.
