Da Vinci Code sequel set for September
The Lost Symbol, the long-delayed Dan Brown thriller featuring Robert Langdon, the protagonist from The Da Vinci Code, will be in bookstores in September.
Knopf Doubleday Publishing Group announced at the London International Book Fair on Monday that Brown’s first book since The Da Vinci Code was published six years ago will hit the shelves Sept. 15 with an initial English-language print run of five million copies.
It was originally scheduled to be published in 2005.
Jason Kaufman, executive editor of Doubleday, said the story unfolds over a 12-hour period and follows Harvard symbologist Langdon “through a masterful and unexpected landscape.”
In a press release, the American author said he spent five years researching the book. “Robert Langdon’s life clearly moves a lot faster than mine,” Brown added.
The Da Vinci Code, Brown’s fourth novel, was a publishing phenomenon with 81 million hardcover copies in print. The British paperback edition spent more than two years in the Sunday Times Top 10 bestsellers’ list, with 68 weeks in the top place, and is Britain’s bestselling paperback novel to date. It has been translated into 51 languages.
It also took some heat for its portrayal of the Catholic Church and its license with facts.
After The Da Vinci Code’s publication, Brown’s earlier novels Angels and Demons, Deception Point and Digital Fortress went on to become international bestsellers.
The 2006 film, The Da Vinci Code, starring Tom Hanks, was a No. 1 box office hit, with receipts of $758 million US. Columbia Pictures will release Angels and Demons on May 15.
