Description
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...
