The Jack Carr Book Club September 2025 selection is THE SECRET OF SECRETS by #1 New York Times bestselling author Dan Brown.

When Robert Langdon travels to Prague with Katherine Solomon—a brilliant noetic scientist on the verge of publishing an explosive discovery about human consciousness—the trip is derailed by a brutal murder and Katherine’s sudden disappearance. Soon, Langdon is targeted by a shadowy organization and hunted by an enemy born from Prague’s most ancient mythology.

What follows is a relentless race through Prague, London, and New York, where Langdon must untangle a web of futuristic science, mystical lore, and deadly secrets. At its core lies a shocking truth about the human mind—one powerful enough to alter the course of history.

Dan Brown is the author of numerous #1 international bestsellers, including The Da Vinci Code, Angels & Demons, The Lost Symbol, Inferno, Origin, and more. His novels have captivated millions of readers with their trademark blend of history, science, and myth, redefining the modern thriller.

This conversation explores Brown’s inspirations for The Secret of Secrets, the enduring legacy of Robert Langdon, and the fine line between science and spirituality in storytelling.
