Origin by Dan Brown

Every Dan Brown novel is a sort of touristic invitation to visit a country!

This time, we're in Spain. It all starts in Bilbao, at the Guggenheim museum, where one of former Langdon's student, Edmond Kirsch,  is about to present a revolutionary vision of the creation of the world and its future.

But he is assassinated during his speech, on the stage, by a former Spanish Admiral, a member of the Palmarian church.

Langdon and the curator of the museum, Ambra Vidal, who is at the same time a friend of the murdered and the fiancée of the future king of Spain, escape in order to find the pass word that will allow them to open the conference that was stopped by the killing of its creator.

And for that, they have to go to Barcelona, where Kirsch lived, in the Casa Mila, built by Gaudi.

Then in the Sagrada Familia.

Lots of dead people around them in one night....Many suspected...

The most interesting part of the book comes from the computer called Winston who helps them, and its role in the whole action is completely revealed at the end of the book.
