just read: Anne Rice, Memnoch The Devil. I am new to this author but if the rest of her work is of the same calibre then let me at it!!
of course the ubiquitous Dan Brown Davinci Code, but may I suggest his other titles : ie. Deception Point, Digital Fortress and Angels and Demons.
But for something light and amusing J.K. Rowlings Harry Potter are all works of Genius!!
