In anticipation of the long-awaited publication of Dan Brown’s fifth novel, THE LOST SYMBOL, on September 15 of this year, Doubleday is pleased to announce the launch of a summer long event featuring an enigmatic array of codes, cryptic trivia, puzzles, secret history, maps, aphorisms, ciphers, arcane knowledge, and more. 


There will be a number of focal points., now deceptively simple in appearance, will reveal more as the summer advances.  There, you will also find links to the official Dan Brown Facebook page and to LOSTSYMBOLBOOK – the official Twitter page for the book.  Daily posts in both spaces, mostly enigmatic in nature, will challenge, educate, intrigue and entertain!


Enjoy your summer… And remember to mark September 15 on your calendars—with a symbol of your choosing.
