Brand new novel, written by Esteban Martin and Andrew Carranza that just came out this year. 

Maria is the heroine and her boyfriend, Miguel is a mathematician; together they succeed in solving a long- kept secret of Christianity and have to search for an ancient relic that Maria's grandfather had in his possession passed down to him by world class architect Grandmaster Antonio Gaudi.   

This book is very similar to The Da Vinci Code, replacing the city of Paris with the Spanish city of Barcelona.  I picked up the hardback novel at the local library and what sparked my interest was the similiarity to Dan Brown's "Code" and the fact that it takes place in beautiful Barcelona.  I loved Da Vinci Code and have also traveled to Barcelona so it all had a sense of familiarity.  It is a puzzle and treasure hunt through all of master architect Gaudi's great buildings and park, many of which I toured through.  It's translated from the Catalan language of the Catalonian region of Northwestern Spain where Barcelona is situated. 

It's a fast read and really moves.  I feel the two collaborating authors were highly influenced by Brown and it's obvious they were.  If you like riddles and mysteries and have an afffinity for Gaudi's architecture (i.e., the famous yet still incomplete La Sagrada Familia church, Park Guell, Casa Batlo (all fascinating and awe-inspiring), then you'd enjoy this book. 

I rate this 4 stars
