The Da Vinci Code is a novel by American author Dan Brown and published in 2003 by Doubleday Fiction (ISBN 0-385-50420-9). This book is one of the best-selling book in the world with 36 million copies (up to August 2005) and has been translated into 44 languages, including Indonesian. Combining the style of a detective, thriller and conspiracy theory, this novel has helped popularize the attention of a theory about the legendary Holy Grail (Holy Grail) and the role of Mary Magdalene in Christian history - the theories considered by Christians as heretical and has been criticized as history is not accurate. This book is the second part of the trilogy that began with the Dan Brown novel Angels and the Devil (Angels and Demons) in 2000, which introduced the character Robert Langdon. Behind all the controversial, the book is still worth the read.
