Il simbolo perduto / Dan Brown

The Lost Symbol, the stunning follow-up to The Da Vinci Code, is a masterstroke of storytelling - a deadly race through a real-world labyrinth of codes and unseen truths...all under the watchful eye of a terrifying villain. Set within the unseen tunnels and temples of Washington, D.C., The Lost Symbol accelerates through a startling landscape toward an unthinkable finale.

Harvard symbologist Robert Langdon is summoned to deliver an evening lecture in the U.S. Capitol. Within minutes of his arrival, the night takes a bizarre turn. A disturbing object - artfully encoded with five ancient symbols - is discovered in the Capitol Building. The object is an ancient invitation, meant to usher its recipient into a long-lost world of hidden esoteric wisdom. And when Langdon's mentor Peter Solomon - prominent Mason and philanthropist - is kidnapped, Langdon's only hope of saving Peter is to accept this invitation and follow wherever it leads him. Langdon finds himself 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.
