Origin is an attempt at answering the questions "Where did we come from and where are we going?" So is this book fiction, faction, thriller, or Sci-fi? I would have to say all of the above. Dan Brown's Professor Langdon once more is caught in the middle of an intriguing plot and sets out to solve Edmond Kirsch's puzzle and yes as always with a pretty woman in tow. Will religion triumph or science? We don't find out till the end and it's worth reading to find out.
