Robert Langdon is invited to a mystery event at the Guggenheim museum by his former student, Edmond Kirsch. Just as Kirsch is about to reveal his discovery disaster strikes, leaving Langdon and museum director, Ambra Vidal to try and get to Edmond's truth. Ambra has her own worries though and it isn't easy for the future king of Spain's fiancee to go on the run. Can Edmond and Ambra get to the secret before it is silenced forever? 
 This is a typical Dan Brown thriller, with an interesting central premise and lots of dashing around well known places before Langdon uses his knowledge of codes and symbols to uncover the truth. As other reviewers have often stated, Dan Brown's novels are definitely of the marmite variety and as I am a fan of both, I enjoyed this just as much as I have enjoyed the others. 
 He'll write more, no doubt, and I'll read them every time.
