Secret of Secrets

I enjoyed this book much more than I thought I was going to. It's been a long time since I've read the others in the series and I think I'd forgotten how good a read they are. The puzzles Robert Langdon solves throughout the story are easy enough that you can solve them before the solutions are revealed, and hard enough that you feel smart for doing so, and the real-life places and organizations referenced are enough to make the story feel relatable even when it's actually pretty far-fetched.
