As she completes the final instalment of the hit Harry Potter book series, author J.K. Rowling has come full circle, doing most of her writing in a café.

The Scottish author has been hard at work writing "huge parts" of Book 7 in a local café, she wrote in an entry posted Tuesday on her website.

"I'm writing scenes that have been planned, in some cases, for a dozen years or even more," Rowling wrote.

"I don't think anyone who has not been in a similar situation can possibly know how this feels: I am alternately elated and overwrought. I both want, and don't want, to finish this book (don't worry, I will)."

The final Harry Potter book, in which the young wizard is expected to engage in an all-out battle with his evil nemesis, Lord Voldemort, is expected for release in summer 2007.

Rowling's newest post also mentioned visiting Leavesden Studios, northwest of London, to check the progress on the fifth instalment of the movie franchise, Harry Potter and the Order of The Phoenix, due out in July 2007.

Rowling, now one of the most famous authors in the world, wrote her first Potter book in Edinburgh cafés 13 years ago.

Whenever her eldest daughter Jessica fell asleep, Rowling would put her into a carriage and wheel her to the nearest café, she has previously recounted on the site.

Once there, she would rush to write as much as she could about the now famous boy wizard, his friends and enemies as well as Hogwarts School of Witchcraft and Wizardry, the magical boarding school they attend.

Fans of the internationally beloved Harry Potter franchise, which has sold more than 300 million books worldwide and been translated into 47 languages, are eagerly awaiting the final book.
