The Secret of Secrets

Robert Langdon returns in the long-awaited, pulse-pounding thriller from the global bestselling author of The Da Vinci Code and Angels & Demons.

Accompanying renowned scholar Katherine Solomon to a lecture in Prague, Langdon’s plans are shattered when she vanishes without a trace from their hotel room. Stranded in a foreign city and pushed far beyond his comfort zone, Langdon must rely on his intellect and intuition to find the woman he loves.

But Prague is a city steeped in legend and haunted by centuries of history. For more than two thousand years, it has absorbed layer upon layer of folklore, mystery, and bloodshed. Now, in its twisting streets and shadowed passageways, an echo from that dark past is closing in on him. To survive, Langdon must unlock hidden codes and symbols buried deep within the city’s fabric—before Katherine is lost forever.

Amid vast castles, towering cathedrals, ancient cemeteries, and labyrinthine tunnels, Langdon finds himself navigating a hidden world that has guarded its secrets for generations. This is a battlefield unlike any he has faced before—one where the fight is not only for his own survival, but for the future of humanity itself.

The Secret of Secrets marks Dan Brown’s first novel in over eight years, heralding the triumphant return of Harvard symbologist Robert Langdon. This time, he confronts a conspiracy that will stretch even his formidable intellect to its limits—and force him to risk everything he holds dear.
