J.K. Rowling is hugely successful right now. She is one of the wealthiest authors in the world, with an estimated net worth of £600 million ($805.9 million), and is still making money from the "Harry Potter" franchise with her new play "Harry Potter and the Cursed Child."
But she's not the highest-paid writer this year.
In August, Forbes released data on the highest-paid authors of 2016, looking at their total earnings — from book sales as well as TV and film adaptations, before taxes — between June 1, 2015 and June 1, 2016.
During this time, the authors who made the ranking collectively made £201.8 million ($269 million).
The highest-paid author on the list made almost five times more than the second wealthiest, showing just how lucrative the book industry has become.
From "The Da Vinci Code" author Dan Brown to "Harry Potter" creator J.K. Rowling, here are the world's highest-paid writers and how much they have made in the last year:
=14. Dan Brown — £7.1 million ($9.5 million)

Dan Brown is best-known as the author of the mystery thriller "The Da Vinci Code," which was turned into a film in 2006, three years after its publication. He is set to publish an abridged version of the novel for young adults on September 8 with Penguin Random House.
=14. Rick Riordan — £7.1 million ($9.5 million)

Rick Riordan made his millions from writing the "Percy Jackson and the Olympians" series. The five-book series, which is about a 12-year-old who discovers he is a son of Poseidon, has since been turned into graphic novels and films.
=14. George R.R. Martin — £7.1 million ($9.5 million)

George R.R. Martin has spent five years writing "The Winds of Winter," the sixth part to his fantasy epic, "A Song of Ice and Fire." It was turned into the HBO television series "Game of Thrones" in 2011, making Martin one of the world's most famous authors.
