"Angels & Demons," the second installment in the "Code" film franchise, hits U.S. theaters May 15.
Like "Code," it is based on a Brown mystery, was directed by Ron Howard and stars Tom Hanks as symbologist Robert Langdon.
Both the film and novel versions of 'Code" were major blockbusters.
Variety.com said it was announced Monday that Brown's third book in the "Code" series, "The Lost Symbol," will be published in the United States and Canada by Doubleday Sept. 15. The entertainment industry trade newspaper also reported that Columbia plans to bring "Symbol" quickly to the big screen.
"This is a great day for readers and booksellers," said Sonny Mehta, chairman/editor-in-chief of the Knopf Doubleday Publishing Group, in announcing the publication date for Brown's next book.
