About this listen

Brought to you by Penguin.

Robert Langdon is back in the long-awaited new race-against-time thriller from the global bestselling author of The Da Vinci Code and Angels and Demons.


Accompanying celebrated academic, Katherine Solomon, to a lecture she’s been invited to give in Prague, Robert Langdon’s world spirals out of control when she disappears without trace from their hotel room. Far from home and well out of his comfort zone, Langdon must pit his wits against forces unknown to recover the woman he loves.

But Prague is an old and dangerous city, steeped in folklore and mystery. For over two thousand years, the tides of history have washed back and forth over it, leaving behind echoes of everything that has gone before. Little can Langdon know that he is being stalked by a spectre from that dark past. He must use all of his arcane knowledge to decipher the world around him before he too is consumed by the rings of treachery and deception that have swallowed Katherine.

Against a backdrop of vast castles, towering churches, graveyards buried twelve deep and labyrinthine underground passages, Langdon must navigate a shadow city hiding in plain sight, a city which has successfully kept its secrets for centuries and will not readily deliver them.

This is a battlefield unlike any he has previously experienced, one on which he must fight not for his only life, but for the future of humanity itself.

The Secret Of Secrets is Dan Brown’s first novel for over eight years and sees the stunning return of Harvard symbologist Robert Langdon, this time pitting his wits against a conspiracy which will test even his considerable brainpower and take him to the edge of losing all that he holds dear…

Editorial Review

The wait is over
After nearly eight years, Dan Brown returns with another thrilling addition to his legendary Robert Langdon series. This time, the professor is in Prague to attend a lecture by noetic scientist Katherine Solomon—a woman he’s also newly dating. The action kicks off quickly with a murder and then a disappearance. From there, the gripping plot spans both continents…and consciousness. Brown’s talent for immediately sucking you into the plot has only strengthened in his near-decade off, and the science explored—along with Brown’s disclaimer at the top of the book that all science and experiments you’ll hear about are real—is chilling. Performed by series narrator Paul Michael, I can safely say The Secret of Secrets was worth the wait.—Katie O., Audible Editor

Sorry Dan, but you dropped the ball this time! I was really looking forward to this book, but it was just going through the motions. To much in depth information! I wanted an edge of the seat story like pasted books! Sorry it missed the mark!
