Harry Potter creator J.K. Rowling is leaving the world of wizards and Muggles and publishing her first novel for grown-ups.

Rowling has reached an agreement with Little, Brown and Company in the U.S. and the U.K. for her first post-Harry novel, the Associated Press reported Thursday.

"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," Rowling said in a statement released by Little, Brown. "The freedom to explore new territory is a gift that Harry's success has brought me, and with that new territory it seemed a logical progression to have a new publisher. I am delighted to have a second publishing home in Little, Brown, and a publishing team that will be a great partner in this new phase of my writing life."

The title, release date and details about the novel have not been announced.

The Potter series has sold more than 400 million copies and the cinematic adaptations of Rowling's books have racked up more than $7 billion in box-office ticket sales.
