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.
