Robert Langdon, Harvard professor of symbology and religious iconology, arrives at the ultramodern Guggenheim Museum in Bilbao to attend a major announcement—the unveiling of a discovery that “will change the face of science forever.” The evening’s host is Edmond Kirsch, a forty-year-old billionaire and futurist whose dazzling high-tech inventions and audacious predictions have made him a renowned global figure. Kirsch, who was one of Langdon’s first students at Harvard two decades earlier, is about to reveal an astonishing breakthrough . . . one that will answer two of the fundamental questions of human existence.
