"Impossible to put down.... Another mind-blowing Robert Langdon story." --The New York Times

Famed Harvard symbologist Robert Langdon answers an unexpected summons to appear at the U.S. Capitol Building. His plans are interrupted when a disturbing object--artfully encoded with five symbols--is discovered in the building. Langdon recognizes in the find an ancient invitation into a lost world of esoteric, potentially dangerous wisdom.

When his mentor Peter Solomon--a long-standing Mason and beloved philanthropist--is kidnapped, Langdon realizes that the only way to save Solomon is to accept the mystical invitation and plunge headlong into a clandestine world of Masonic secrets, hidden history, and one inconceivable truth ... all under the watchful eye of Dan Brown's most terrifying villain to date.
