Dan Brown's Robert Langdon Books in Order: The Complete Reading Guide

If you've seen The Secret of Secrets on the shelves this summer and fancy getting into Dan Brown properly, you're in good company. His Robert Langdon thrillers have been mixing symbology, secret societies and globe-trotting chases for over two decades, and the paperback release of book six has sent readers back to the start of the series. This guide sets out the correct reading order, what each book is actually about, and where to find them at a decent price if you're building the full set.

Do you need to read the Robert Langdon books in order?

Each novel stands alone as a self-contained mystery, so you won't be lost picking up any one of them cold. However, characters, relationships and running themes do carry across the series, particularly between The Lost Symbol and The Secret of Secrets, where a major relationship introduced in book three becomes central to the plot of book six. For the fullest experience, reading in publication order is the way to go.

The Robert Langdon reading order

1. Angels & Demons (2000)

The book that started it all, published in 2000, this first outing takes Harvard symbologist Robert Langdon to the Vatican, where a centuries-old secret society and a stolen canister of antimatter threaten to bring the Catholic Church to its knees. It's a fast, puzzle-driven introduction to Langdon's world of hidden codes and ancient conspiracies.

2. The Da Vinci Code (2003)

The book that turned Dan Brown into a household name. Langdon is pulled into a murder investigation at the Louvre in Paris that unravels into a hunt for a secret protected by a shadowy brotherhood, working alongside French cryptographer Sophie Neveu. If you've never read it, it remains the obvious entry point for anyone who wants to understand why this series became such a phenomenon.

3. The Lost Symbol (2009)

Langdon heads to Washington D.C. after a bizarre invitation from an old friend turns into a race against time involving the Freemasons, hidden codes buried in the city's monuments, and a discovery that reshapes how Langdon sees the world. This is also where readers first meet noetic scientist Katherine Solomon, a character who becomes far more important later in the series.

4. Inferno (2013)

Langdon wakes up in a Florence hospital with no memory of the previous 48 hours, only fragmented, terrifying visions of Dante's Inferno. What follows is a chase through Florence, Venice and Istanbul to stop a radical plan built around ideas of overpopulation. It's one of the more atmospheric entries, leaning heavily on Renaissance art and architecture.

5. Origin (2017)

Langdon travels to the ultramodern Guggenheim Museum in Bilbao to attend a major announcement from Edmond Kirsch, a billionaire futurist and former student who claims to have found the answer to two of humanity's oldest questions. When Kirsch is killed before he can reveal his discovery, Langdon and museum director Ambra Vidal must finish what he started, with the help of an AI assistant called Winston. It's the most tech-focused book in the series.

6. The Secret of Secrets (2025/2026)

The newest instalment, released in UK paperback this July, brings Langdon back alongside Katherine Solomon from The Lost Symbol. The novel is set primarily in Prague, with the action extending to London and New York, as Langdon attends a lecture by Solomon, now a prominent noetic scientist with whom he has recently begun a relationship. The plot weaves together consciousness research, covert intelligence work and centuries-old mythology, making it a fitting, and fairly emotional, capstone for long-time readers of the series.

Should you start with the film adaptations instead?

Three of the six novels have been adapted for the big screen with Tom Hanks as Langdon: The Da Vinci Code, Angels & Demons and Inferno, while The Lost Symbol became a television series with a different actor in the role. If you've only seen the films, the books go into far more depth on the puzzles, the history and Langdon's internal reasoning, so they're worth reading even if you already know how the story ends.

Getting the whole series without spending a fortune

Because the Robert Langdon novels are chunky (several run past 600 pages) and there are now six of them, buying new copies one at a time can add up quickly. At LetsBuyBooks we sell brand-new copies at heavily discounted prices with fast UK delivery, so it's a straightforward way to fill in the gaps in your collection or pick up the whole run in one go. It's worth browsing the Crime, Thriller & Mystery collection for individual titles, or the Box Sets & Collections range if you'd rather grab the earlier books together and pick up the latest paperback separately.

Other ways to approach the series

• Reading purely by setting: if you love art history and want the most visually rich entries first, start with The Da Vinci Code (Paris) and Inferno (Florence and Venice) before moving on to the others.
• Reading for the twists: Angels & Demons and The Lost Symbol are generally considered to have the most surprising final reveals, so save them if you want to build up to the biggest shocks.
• Reading for the newest release: if you've already read the first five and just want to catch up, The Secret of Secrets can be read on its own, though the emotional weight lands harder if you remember Katherine Solomon from The Lost Symbol.

Who will enjoy this series?

These books suit readers who enjoy puzzles, codes and a fast pace over literary style, alongside history buffs who like real locations, artworks and institutions woven into a thriller plot. They sit comfortably alongside other crime and thriller favourites, and fans of conspiracy-driven plots will also find plenty to enjoy in the wider fiction range. If you're buying for someone who devours a book in a weekend, these are reliably long, at several hundred pages each, making them good value for a summer of reading.

Frequently asked questions

Is The Secret of Secrets the last Robert Langdon book?

There's no confirmation from Dan Brown that the series is finished, but The Secret of Secrets does feel like it draws several long-running threads to a close, particularly around Langdon's personal life. Whether more Langdon adventures follow remains to be seen.

Can I read The Secret of Secrets without reading the others first?

Yes, it works as a standalone mystery, but you'll get more out of the relationship between Langdon and Katherine Solomon if you've already read The Lost Symbol, where she first appears.

Which Robert Langdon book is the best place to start?

Angels & Demons is the correct chronological starting point, though many readers still discover the series through The Da Vinci Code first, since that was the book that made Dan Brown a household name in the UK. Either works as an entry point; just be aware that starting with The Da Vinci Code means going back a step for Langdon's first outing afterwards.

Are the Robert Langdon books suitable for teenagers?

They're written for an adult audience and do contain violence and some grim crime scenes, so they tend to suit older teenage readers and adults rather than younger children. If you're buying for a teenager who enjoys puzzles and history, they're often a popular next step up from younger mystery series.

Final thoughts

Whether you're starting completely fresh or you've been waiting for The Secret of Secrets to land in paperback, the Robert Langdon series rewards reading in order: the callbacks and returning characters simply make more sense that way. Start with Angels & Demons, work your way through to the newest release, and you'll understand exactly why this series has kept readers hooked for over 25 years.
