Da Vinci Code is my favorite book I like Da Vinci Code written by American author Dan Brown and first published in 2003 that has become a worldwide bestseller. The plot of this book concerns the attempts of Dr. Robert Langdon, Professor at Harvard University, to solve the murder of Jacques Sauniere, the curator of the Louvre Museum in Paris, after Suniere's body had been found inside the Louvre naked with a cryptic message written on his torso in his own blood and posed like Leonardo da Vinci's famous drawing. This book has been criticized by many scholars, but it has undoubtedly helped to broaden my horizons about certain theories concerning the legend of the Holy Grail and the role of Mary Magdalene in the history of Christianity.
