I read "The Da Vinci Code" long before it became the big deal it is now, well before it was a twinkle in Ron Howard's eye. Re-reading it tonight I am reminded, as I was the first time, how much I dislike organized Christianity and the Catholic church in particular.
If you want to know more, read it. It's serious brain candy. Like a bag of Reese's Peanut Butter Cups.
