When one picks up a Dan Brown book there are certain expectations. First one can look forward to a fast-based adventure pitting the intellect of Robert Langdon against dark forces intent on creating mayhem of one sort or another. One expects that religion or religious institutions will play a central role in the story. One can expect that there will be puzzles to be solved and mysteries within mysteries. One can expect murderous sociopaths and police of questionable loyalty. One can expect that there will be a considerable quantity of payload in the form of interesting, arcane information. One can expect that once begun it will be a difficult book to put down. And Brown delivers on all of the above. If you are looking for great literature, look elsewhere. That is not Brown’s beat. Be prepared for some eye-rolling, as hyper-intelligent people make glaringly stupid decisions, all in the service of moving the plot along. And there are some notions at the end of the book that may be a bit much to swallow. But it is all in fun. It is what it is. Enjoy.
