JK Rowling's had loads to do in the run up to the release of the final book in the Harry Potter series. She admitted on her website that she was feeling nervous about the launch, but just moments before she gave a moonlight reading in London, she took time out for a quick chat with Newsround's Lizo.
It's been an incredible 10-year journey. What's it like reaching the end of all of this?
JK: I can't tell you. I've never been so excited about a launch. I'm really emotional as well. I could cry. I'm very happy tonight; this is my favourite book of the series, so that is the best way to end this. Whether people like it or not, I really like it. As a writer, when you strip it all back, that's what it's about.
How does tonight compare to some of the other highlights of the last 10 years of Harry Potter?
JK: Tonight has got to be up there. It's going to be one of my eternal memories of the whole thing. Today's really been a day to look back and remember how it used to be. I've had many conversations with people like my American editor in New York. We've just been reminiscing about what it's been like over the past 10 years.
We've had a week full of people leaking things that they say are spoilers and the incredible secrecy that's built up around it.JK: I think the two things feed off each other. We tried to protect the stories so that children particularly could reach them and enjoy the pleasure of reading the book. Therefore, inevitably, there are people who want to try and break the embargo.
You become locked into this horrible situation. I'm so grateful that nearly everyone kept to the embargo coz I've just sat in the middle of all these children and they're all saying "what happens, what happens?" and they don't know. That's miraculous really!
When will we be hearing from you again?JK: Well, I'm sure you will hear from me again but at the moment I'm saying, and I mean it, I really would like to take a break for a while and I think I probably need to because this has been so massive. I probably need not to do it for a while and get some perspective back into life.
