JK Rowling, the British author who created the extraordinary saga of boy wizard Harry Potter intends to take a break and reorganize her life.

Rowling, the 41-year-old British woman, began writing first Harry Potter book ten years ago. She  launched the last and seventh volume of Harry Potter adventures, “Harry Potter and the Deathly Hallows” in a private reading session at London's Natural History Museum one minute past midnight on Saturday.

"I've loved writing about Harry," Rowling said shortly before her last volume of the Potter saga was due to be released. "But now I need some time out."

"I can't promise anything to anyone," she said to speculation about a possible continuation of the Potter series. First of all, she needed a break now, Rowling said.

But even if she was going to miss Harry, the story was not yet over for her.

"My two youngest children don't really know yet who Harry Potter is. I'm so looking forward to share the book with them, when they're old enough - it helps me not to feel too sad that it's all over now."

During his week end, "Pottermania" has reached a peak as the fans could get their hands on “Harry Potter and the Deathly Hallows”. In UK, according to book-sellers, the book has set a new record as 15 copies were sold per second.

UK publisher Bloomsburg didn’t reveal any official data, but according to some estimation 2.5 million will be sold in the first weekend. Also, sales of 350,000 are expected in Australia and with a record-breaking, first run of 12 million copies, US publisher Scholastic hopes the magic will hold.

So far, Rowling's books have sold 325 million copies in 64 languages.

Meanwhile, Bloomsbury continues to investigate who is responsible for the leaked copies of the book, which appeared online on Thursday. "We are working very diligently with Scholastic in the U.S. to try to determine the people behind the leaks," Bloomsbury's Lucy Holden said yesterday.

"You can't control what people place on the Internet, of course, and it's very easy nowadays to mock up pages with modern technology to make it look like it's the real thing. But we want to find out who's doing it."
