The Lost Symbol Book Club Guide: Questions & Activities

The Lost Symbol Book Club: A Night of Secrets, Symbols & Science

If you’re looking for a book club pick that blends high-speed thrills with deep philosophical questions, The Lost Symbol might be your perfect match.

Dan Brown’s third Robert Langdon novel doesn’t just entertain—it challenges readers to think about hidden knowledge, spiritual beliefs, and the power of the human mind. And as the only book in the series set in the United States, it brings a fresh setting: Washington, D.C.—a city I lived and worked in for years, and one I still love exploring through Langdon’s lens.

This guide will help you spark meaningful discussions and add a little mystery to your meeting. Whether you’re first-timers or Langdon loyalists like me, The Lost Symbol offers layers worth working through together.

Top Discussion Questions for The Lost Symbol

For me, there were several moments while reading The Lost Symbol when I found myself wishing I had someone to unpack the themes with. With your book club, these questions will help you zero in on those ideas and spark a truly thought-provoking discussion.

1. Why do you think this is the only Robert Langdon book set in the U.S.? What other settings would you like to see in future Robert Langdon iterations?
2. What did you know about “brotherhoods” like the Freemasons before reading this? Did this change your opinion at all?
3. Have you been to Washington, D.C. and seen the sites mentioned? Did this book reveal something you hadn’t known before?
4. Had you ever heard of Noetic science?  What about the law of attraction or other “power of the mind” philosophies? How did the book shape or shift your thinking about the power of thought?
5. Did you figure out the villain in advance?  What did that add to the story?
6. Do you meditate?  Have you tried before? Why or why not?  Are there specific tools you use?
7. One theme is that many religions share a core belief: “God is within us.” How does that idea sit with you?
8. One of the lines in the book is “We all fear what we do not understand.” Do you agree with this?  What are some real-world (or real-history) examples of this?
9. How did you feel about the concept of a mystical portal leading to hidden truths? Was the payoff worth the buildup?
10. Katherine says “don’t think of it as faith. Think of it simply as changing your perspective, accepting that the world is not precisely as you imagine. Historically, every major scientific breakthrough began with a simple idea that threatened to overturn all of our beliefs.” Do you think this is true? What do you think we have left to “discover”?

5+ Fun Activities to Add Depth to Your Evening

Activities are certainly optional for any book club evening, but adding any of these to your discussion of The Lost Symbol might help you get a little deeper into the story and make it more personal.

• To create an ambiance that mimics a theme throughout the book: Put a football game on mute in the background, even better if it’s a Redskins (now Commanders game).
• Tattoos are certainly a big part of the novel—share your tattoo story!  Do you have any? Have you been thinking about one? Do you have any friends with memorable tattoos?
• Have you looked closely at dollar bills before?  Bring some out to examine and discuss the emblems. Did you already know about some of them? Can you think of any other examples of symbols hiding in plain sight? (Reader’s Digest has a fun read to explain the symbols.)
• Look up the Capitol dome fresco (the Apotheosis of Washington) and study the painting; what stands out about mixing scientific heroes with divine imagery?
• The characters visit a “Chamber of Reflection” which is filled with “skull and crossed bones, scythe, hourglass, sulfur, salt, blank paper, a candle, et cetera.” Because “The symbols of death inspire Masons to ponder how better to lead their lives while on this earth.” If you were to create a mini meditation space, what would you include and why?
• Try this power of thought exercise and discuss how words and mindset influence confidence and body tension:
  • Have one person stand with an arm extended to the side.
  • Another presses gently down on that while the first person resists.
  • First, have the participant with the arm out  repeat a negative statement (“I am weak,” “I can’t do this”).
  • Then try again with a positive statement (“I am strong,” “I can handle anything”).
  • Usually the arm feels stronger after positive affirmations — not because of magic, but because of subtle posture and muscle engagement changes brought on by the confident statements.

Final Thoughts On Creating a Great Book Club Discussion for The Lost Symbol

There aren’t very many thrillers worthy of a book club discussion, but The Lost Symbol is one of those rare thrillers that practically begs to be experienced with a group. With its blend of Washington, D.C. landmarks, secret societies, and mind-bending scientific questions, it offers the perfect mix of plot, history, and big ideas for a memorable book club night.

Whether you’re dissecting the Freemasons’ symbolism, debating the power of thought, or pulling up photos of the Capitol dome to compare to the story, this is a book that invites curiosity. Lean into that. Bring maps, examine dollar-bill iconography, try a meditation exercise, or even plan a future field trip—D.C. makes a fantastic literary getaway, and many of the locations in the novel (like the fascinating House of the Temple) are open to visitors.

If your group loves travel, mysteries, and stories that spark conversation long after the last page, The Lost Symbol delivers. And who knows—your discussion might even inspire your next bookish adventure.
