JK Rowling: New Book for Adults Will Be ‘Very Different’

J.K. Rowling is ditching the world of teenage wizardry to pen a new book for adults that will be "very different" from her "Harry Potter" series.

Rowling signed a deal with Little, Brown's British and U.S. divisions to release her first adult book. Although the title, release date and details about the book have been talked about, nothing official has been provided.

Rowling's agent, Neil Blair, said she would remain with Bloomsbury in Britain for the Potter books. Rowling's seventh and final Potter story came out in 2007.

The 46-year-old author said in a statement, "Although I've enjoyed writing it every bit as much, my next book will be very different to the Harry Potter series, which has been published so brilliantly by Bloomsbury and my other publishers around the world."

She says her new found freedom is a gift Harry's success has brought her.

Rowling's Potter series about a boy wizard was published between 1997 and 2007 and broke sales records worldwide.

The series has sold more than 450 million copies and been translated into 74 languages.

 The beloved stories were turned into eight blockbuster films starring Daniel Radcliffe and culminated with last year's "Harry Potter and the Deathly Hallows: Part 2."

The Potter brand is estimated to be worth $15 billion by trade publication Advertising Age, while Forbes estimates Rowling is worth well over $1 billion.

Little, Brown publisher David Shelly said in a statement, "For me, quite simply, it is a personal and professional dream come true to be working with J.K. Rowling. She is one of the best storytellers in the world, and I am looking forward enormously to helping bring her new novel for adults to her fans and admirers, and to introducing her writing to new readers the world over."
