Dan Brown does it again. I really liked this book, in particularly because of the tension between religion and atheism. There was lots of excitement, danger, puzzles to figure out, a fascinating AI computer, snippets of history, philosophy, theology, etc., and some wonderful twists and turns. My only complaint is the hero–Robert Langton. He seems to think he’s the most knowledgeable, charming man in the world. He grates on my nerves. Still, I loved the book!
