The Independent is reporting that 2.5 million copies of '
Half-Blood Prince' remain unsold in the US. The chairman for Scholastic, Richard Robinson, expects that the release of '
Goblet of Fire' will create a renewed interest in the novel series however the release of '
Prisoner of Azkaban' last year resulted in the sale of only 60,000 copies of the book.
