One lucky teenage Potter fan is celebrating winning the right to do the only UK TV interview with JK Rowling when the sixth Potter book is released.
Owen Jones beat thousands of other Potter fans to the prize, which he won by coming first in a TV quiz.
The 14-year-old got to the quiz round by giving judges a list of questions he would most like to put to JK.
Owen, from Cardiff, then took part in the TV quiz along with his mum, Allison, also a massive Potter fan.
Owen explained how he got through the first stage of the competition by impressing judges with his searching questions.
"I told the judges I would like to ask her if Harry Potter's life was a kind of childhood fantasy for her, and of course, what's going to happen in the next book," said Owen.
"Then I had to face the quiz. The moment I came through the door from school mum was firing Harry Potter questions at me," he added.
Harry Potter and the Half-Blood Prince will be released at midnight on Friday and Owen's interview with JK will be shown next Sunday on ITV1 at 5.30pm.
Signed book donation
JK Rowling has also announced she will donate her first signed copy of the Half-Blood Prince to the National Library of Scotland in Edinburgh on Saturday 16 July.
Martyn Wade, its National Librarian, said he was especially delighted with the donation as library is very close to where JK wrote Harry Potter and the Philosopher's Stone.
