Robert Langdon, Harvard professor of symbology and religious iconology, arrives at the Guggenheim Museum Bilbao to attend the unveiling of a discovery that will change the face of science forever. The evening's host is his friend and former student, Edmond Kirsch, a forty-year-old tech magnate whose dazzling inventions and audacious predictions have made him a controversial figure around the world. This evening is to be no exception: he claims he will reveal an astonishing scientific breakthrough to challenge the fundamentals of human existence. But Langdon and several hundred other guests are left reeling when the meticulously orchestrated evening is blown apart before Kirsch's precious discovery can be revealed. With his life under threat, Langdon is forced into a desperate bid to escape, along with the museum's director, Ambra Vidal. Together they flee to Barcelona on a perilous quest to locate a cryptic password that will unlock Kirsch's secret. In their path lie dark forces which will do anything to stop them. To evade a tormented enemy who is one step ahead of them at every turn, Langdon and Vidal must navigate labyrinthine passageways of hidden history and ancient religion. On a trail marked only by enigmatic symbols and elusive modern art, Langdon and Vidal uncover the clues that will bring them face-to-face with a world-shaking truth that has remained buried - until now.
—Publisher's description.
Dan Brown is an American author of thriller fiction, best known for the 2003 bestselling novel, *The Da Vinci Code*. Brown's novels, which are treasure hunts set in a 24-hour time period, feature the recurring themes of cryptography, keys, symbols, codes, and conspiracy theories. His books have been translated into over 40 languages, and as of 2009, sold over 80 million copies.
Brown's novels that feature the lead character Robert Langdon also include historical themes and Christianity as recurring motifs, and as a result, have generated controversy. Brown states on his website that his books are not anti-Christian, though he is on a 'constant spiritual journey' himself, and says of his book *The Da Vinci Code* that it is simply "an entertaining story that promotes spiritual discussion and debate" and suggests that the book may be used "as a positive catalyst for introspection and exploration of our faith."
