Robert Langdon goes to Prague for a lecture by Katherine Solomon, a noetic scientist he has started seeing. She is about to publish a book on consciousness that would upset a lot of settled ideas. A murder breaks the trip open, Katherine vanishes with her manuscript, and Langdon is chased through Prague, London, and New York by an organization with resources and by something that seems to have walked out of Prague’s oldest legends.
Dan Brown’s first Langdon novel since Origin. Hardcover, 688 pages, from Doubleday, published September 2025. Debuted at number one on the New York Times list.
The usual Brown mix: real locations, real science pushed a step, and a chapter break every few pages.
