And when Langdon's revered mentor is brutally kidnapped, he realizes his only chance to save his old friend is to accept this sinister summons. All that was familiar is transformed into a shadowy, clandestine world in which Masonic secrets and never-before-seen revelations seem to be leading him to a single impossible and inconceivable truth.
