New Harry Potter book nearly finished

JK Rowling says she is just weeks away from finishing Harry Potter And The Order Of The Phoenix.

Rowling says she's "very happy" with the fifth book.

She's also revealed it is longer than Goblet Of Fire.

"At the moment it's 38 chapters," she said. That's one chapter longer than the last book.

"I'm really pleased with it," Rowling said. 'I'm just going to tweak it a tiny bit more, then the publishers will have it."

The book should be in the shops in about five months.
