The Secret of Secrets: A Novel

Dan Brown Β· 2025
πŸŽ™ Narrated by Paul Michael (Random House Audio), the established narrator of the Robert Langdon series
57/100

Langdon's back chasing a scientist and her research into consciousness through Prague, and it moves fast, but plenty of critics felt like they'd read this puzzle-box before, and the "noetic science" hook is a hard sell for some. The narration by Paul Michael is clean and well-paced if you're already invested in the series, but the story itself doesn't quite earn a strong recommendation on its own merits.
