I was waiting for a couple holds from the library, so decided to finally read The Da Vinci Code while I was waiting. God, it's hokey. I can't tell if Dan Brown thought the big reveal of the "secret password" was supposed to make us all say "Of course! Why didn't I think of that?" or make us internally yell at the supposed 'expert' characters who were so stumped by it for so long, but it was definitely the latter for me. :)
Anyway, it is mildly entertaining for all its faults.
