The Harry Potter author is set to write her first novel aimed at grown-ups.
Although Harry Potter had a universal appeal, attracting millions of readers around the world, they were originally intended for a younger audience.
The 46-year-old Scot has been handed a £5 million deal for the novel.
'Although I’ve enjoyed writing it every bit as much, my next book will be very different to the Harry Potter series,' Rowling explained in a statement.
‘The freedom to explore new territory is a gift that Harry’s success has brought me.'
