Welcome to my weekly segment, Waiting on Wednesday, where I look at upcoming books that I am planning to order and review in the next few months and which I think I will really enjoy. Stay tuned to see reviews of these books when I get a copy of them. For this latest Waiting on Wednesday, I highlight one of the top and most anticipated thrillers of 2025 with the exciting new Dan Brown book, The Secret of Secrets.

Dan Brown is an author who leads very little introduction, having been one of the most recognisable authors of the early 21st century. Thanks primarily to his Robert Langdon books and the resulting film adaptations, Brown received a lot of recognition for his compelling and history laden thrillers that followed the titular character, symbologist Robert Langdon, as he attempts to unwind elaborate mysteries from history. Books and films like Angels & Demons, The Da Vinci Code, The Lost Symbol, Inferno and Origin, enthralled audiences for much of the 2000s and 2010s, and I personally had fun with several of them when I first getting into thriller fiction.
After several years away, Brown is returning in 2025 with a brand-new Robert Langdon novel, The Secret of Secrets. Needless to say, I am quite excited for The Secret of Secrets, not only because it sounds really cool, but because it’s the first Robert Langdon book released since I started seriously reading and reviewing thriller fiction for this blog. Set for release in September 2025, The Secret of Secrets is highly intriguing, and I love the sound of the plot below.
Plot Synopsis:
The thrilling and long-awaited new Robert Langdon novel from globally bestselling author Dan Brown.
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…
It looks like Brown has pulled together an excellent and elaborate plot for The Secret of Secrets, and I am very interested in seeing Prague through Dan Brown and Robert Langdon’s eyes. The unique history of the city is going to be a fantastic part of The Secret of Secrets, and I cannot wait to see how Brown will work them into the plot. I have no doubt the central thriller storyline is going to be particularly awesome and having the opportunity to once again see Langdon running around a European city, solving historical clues and deciphering elaborate puzzles is going to be great.
Honestly, the moment I heard that there was a new Dan Brown novel coming out in 2025, I knew that I was going to be grabbing this book. Brown is too iconic an author for a reviewer not to check out, and I have honestly had a lot of fun with his previous books and some of the movies based around them. As such, The Secret of Secrets is now very high up my to-read list for the second half of 2025, and I am sure that I will have an exceptional time reading this upcoming book. It will be really amazing to get more Dan Brown this year, and The Secret of Secrets is going to be so damn good.
