Harry Potter author J K Rowling has revealed for the first time that there's a major death in the next Potter adventure.
She also said that the almost finished fifth book is much darker in tone than the previous stories.
38 chapters long!
Speaking to Lizo at the world premiere of The Chamber of Secrets she described what was in store in The Order of the Phoenix.
"It is dark," she said. "There's a bad death in it that I haven't enjoyed writing."
She said: "At the moment it's 38 chapters."
That's a chapter longer than the last book!
She's now putting the finishing touches to the manuscript which she says is just "weeks away" from being delivered to her publishers.
"I'm really pleased with it," she said. '[I'm] just going to tweak it a tiny bit more, then the publishers will have it."
The book should hopefully be ready in the shops sometime next year.
