We read The Da Vinci Code by Dan Brown.
There's a murder at the Louvre and Robert Langdon must solve the mystery of the man's death. Before the man died, he created a code for his treasured secret to not be forgotten. The man's granddaughter agent Neveu helps Langdon solve the murder, but they must run from the police. The police think that they did it! This story tells the truth about the Holy Grail in all its glory.
I wasn't a huge fan of his writing style; he liked to describe things that didn't need to be described or just use words that didn't need to be there in the first place. Also, his characters were very two-dimensional; they all reminded me of cardboard cutouts with one personality.
I would give this book
It dragged a bit, but the plot twists were really fantastic.
