I were reading Da vinci code. After reading Angels and Demons I got extremely interested in literature and the writing world in general.
Angels and Demons and Da vinci code are novels written by Dan Brown; these novels are about sings, antique mysteries, thriller and some touch of action. It is really catchy how Dan Brown made a full story based on buildings and places and probably secrets that already exist, but you didn't know.

I haven't finished Da vinci code, but I full read Angels and Demons and is so unbelievable.
