Published across ten years between 1997 and 2007, the seven books in the Harry Potter series saw J.K. Rowling emerge to meteoric fame, becoming one of the most well-known authors across the world, with book sales topping more than 450m., earning her a place among the richest of the rich.

Not wanting to rest on her laurels, Publisher’s Lunch report, via Collider, that Rowling has officially announced that she’ll be writing her first novel aimed at adults, with UK publishing house Little, Brown getting the global English rights to the novel when it’s finished.

Expectedly, Rowling hasn’t released any details of exactly what we can expect from the new work, but she has said that it will be very different to the series that has made her famous:

“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. 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.”

And just as plot details haven’t been announced, we’re of course still in the dark as to when we might expect it and how far Rowling currently is with the project, but,

“All other details–title, pub date “and further details about the novel will be announced later in the year.”

So sit tight. Needless to say, the world waits with baited breath to see what the author will bring us next. She’s spoken in the past about departing from the fantasy genre with a new novel like this; let us know in the comments below if there’s a genre you’d love to see her take on next!
