Currently hacking my way through Dan Brown's The Lost Symbol.
I am not a huge fan of Brown's books, which I find a little thin on substance, but a friend at work gave me the book and told me to read it, and Brown is a quick read so what the heck.
EDIT: So I finished it. Not the greatest book in the world, and a few things about it bugged me. For starters there were two major mysteries, or twists, in the story which I easily guessed early on, making the rest of the book a bit boring to trudge through.
In addition, Dan Brown describes the King Street Metro train station in Alexandria, Virginia, as having a tunnel at the end of it, as if it's an underground station, but that is completely wrong. King St. is an elevated rail station.
Makes me wonder how sloppy the rest of his setting research is.
