In this stunning follow-up to the global phenomenon The Da Vinci Code , Dan Brown demonstrates once again why he is the world's most popular thriller writer. The Lost Symbol is a masterstroke of storytelling—a deadly race through a real-world labyrinth of codes, secrets, and unseen truths . . . all under the watchful eye of Brown's most terrifying villain to date. Set within the hidden chambers, tunnels, and temples of Washington, D.C., The Lost Symbol accelerates through a startling landscape toward an unthinkable finale.

As the story opens, Harvard symbologist Robert Langdon is summoned unexpectedly to deliver an evening lecture in the U.S. Capitol Building. Within minutes of his arrival, however, the night takes a bizarre turn. A disturbing object —artfully encoded with five symbols—is discovered in the Capitol Building. Langdon recognizes the object as an ancient invitation . . . one meant to usher its recipient into a long-lost world of esoteric wisdom.

When Langdon's beloved mentor, Peter Solomon—a prominent Mason and philanthropist —is brutally kidnapped, Langdon realizes his only hope of saving Peter is to accept this mystical invitation and follow wherever it leads him. Langdon is instantly plunged into a clandestine world of Masonic secrets, hidden history, and never-before-seen locations—all of which seem to be dragging him toward a single, inconceivable truth.

In this new novel, he again challenges readers with an intelligent, lightning-paced story that offers surprises at every turn. The Lost Symbol is exactly what Brown's fans have been waiting for . . . his most thrilling novel yet.
