The Lost Symbol by Dan Brown

About the book

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.
