Da Vinci Code Sequel Novel Set for September Release

Following a six-year wait, the much anticipated sequel to Dan Brown's best seller, The Da Vinci Code, is set for a Sept. 15 release, according to People.com.

The book, titled The Lost Symbol, will have an initial printing run of 5 million copies, and was already No. 1 on BarnesandNoble.com by Monday night, months ahead of its scheduled release, the Associated Press reported.

Details of the plot are being closely guarded for now, but initial reports reveal that the story takes place over half a day in the life of Harvard symbologist Robert Langdon, hero of The Da Vinci Code.

Author Dan Brown shed a little extra light on Langdon's newest adventure: "Weaving five years of research into the story's 12-hour timeframe was an exhilarating challenge," he said. "Robert Langdon's life clearly moves a lot faster than mine."

Brown's editor, Jason Kaufman, has also reportedly chimed in on the setting of The Lost Symbol, describing it as "a masterful and unexpected new landscape," according to BBC News.

The Da Vinci Code was published in 2003 and became a worldwide phenomenon, selling 81 million copies and inspiring a blockbuster film starring Tom Hanks. The movie went on to gross more than $700 million at the box office, and a second film starring Hanks as Langdon will appear this May, when the adaptation of Brown's Da Vinci prequel, Angels and Demons, is released.
