Harry Potter and the Half-Blood Prince

The sixth Harry Potter book

JK Rowling revealed the secret title of the eagerly-awaited sixth book in June 2004.

The book will be called Harry Potter and the Half-Blood Prince. The title was discovered on the JK Rawling’s website by thousands of fans who followed the clues.

JK Rowling said: “Well, the door opened at last and I showed you the title of Book Six — the title I have been using in my head for ages.”

A half-blood is the offspring of a wizard or witch and a Muggle - like both Harry and Lord Voldemort.

But neither of them are the half-born prince of the title.

The book will be published on 16th July 2005. It will be available on that date in the UK, the US, Canada, Australia, New Zealand and South Africa.
