Proiskhozhdenie - Braun D.

Robert Langdon arrives at the Guggenheim Museum in Bilbao at the invitation of friend and former student Edmond Kirsch. A billionaire and computer guru, he is known for his amazing discoveries and predictions. And this evening Kirsch is going to "turn over all modern scientific ideas about the world" by answering two major questions that have been of concern to humanity throughout history:
Where are we from?
What's in store for us?
However, before Edmond manages to make a statement, the luxurious reception turns into chaos. Langdon and the director of the museum, the beautiful Ambra Vidal, miraculously manages to escape.
Now their way lies in Barcelona, where Kirsch left for his teacher a coded key to a secret that can shake the very foundations of humanity's ideas about itself. A mystery that has been buried for centuries in the darkness of oblivion. The mystery that might never be seen by the light is at least as those who persecute Langdon and Vidal and are willing to do anything to prevent them from revealing the truth.
