Description

INSTANT 1 NEW YORK TIMES BESTSELLER THE NEW ROBERT LANGDON THRILLER FROM THE ICONIC AUTHOR OF THE DA VINCI CODE “A master of the brainy, twisty thriller. . . . The Secret of Secrets is perhaps his most ambitious undertaking yet: a dense thriller that is also a meditation on the nature, and the possible future, of human consciousness.”—Los Angeles Times “So riveting you’ll want to clear your calendar.”—USA Today Robert Langdon, esteemed professor of symbology, has traveled to Prague to attend a groundbreaking lecture by Katherine Solomon—a prominent noetic scientist with whom he has recently begun a romantic relationship. Katherine is on the verge of publishing a breakthrough book that contains explosive scientific discoveries about the nature of human consciousness . . . revelations that threaten to disrupt centuries of established belief. When a brutal murder catapults the trip into chaos, Katherine suddenly goes missing—and her manuscript disappears. Desperate to find the woman he loves, Langdon embarks on a thrilling race through the mystical landscape of Prague, ruthlessly hunted by a powerful organization and a chilling assailant sprung from the city’s ancient mythology. As the action expands to London and New York, Langdon plunges into the dual worlds of futuristic science and historical lore—navigating a labyrinth of codes and symbols . . . and finally uncovering a shocking truth about a secret project that will forever change the way we think about the human mind.

Once again, Brown makes me question reality.
Format: Hardcover
WOW! If you love thrillers, read this book! It has been more than two decades since I first picked up “The Da Vinci Code,” a novel that consumed me so thoroughly I finished it in just two days. Now, with Dan Brown’s latest work, “The Secret of Secrets,” I felt that familiar pull again; though this time it took me five days to reach the end, which i just did this morning. That pace says far more about me than about the book: I’m in my fifties now, working 50-hour weeks, need 8 hours of sleep a night,and simply can’t devour novels at the same clip I once did. Yet, despite the slower progress, Brown’s new novel gripped me with the same intensity as his modern classic. From the very first chapters, The Secret of Secrets announces itself as a return to form. Brown once again marries history, science, and religion with razor-edged suspense, challenging readers to question what they thought they knew about the world. Like The Da Vinci Code, this is not a passive read; it’s an active experience. I frequently found myself pausing mid-chapter to Google frontier scientific research, a legend, or a location, just to see how much of it was grounded in fact. Brown has always excelled at blurring the lines between scholarship and speculation, and here he does it with a renewed sharpness. The book unfolds across an astonishing 140 chapters, each one a tightly wound spring of tension. True to form, Brown structures his narrative around cliffhangers that almost dare you to set the book down, only to ensure you’ll pick it right back up. Every chapter ends with a twist or revelation that spins the story in a fresh direction. The effect is relentless forward momentum driven by the kinetic circumstances thrown at Robert Langdon, a hallmark of Brown’s thrillers, and here it feels particularly refined. As ever, the stakes are sky-high. The central mystery of The Secret of Secrets is nothing less than civilization-shaking, touching on ideas that strike at the core of belief, truth, and the hidden forces that shape human history. Brown’s great gift is to make you feel those stakes personally, as if the very fabric of your own worldview is unraveling alongside his protagonist’s. The suspense never lets up, and just when you think you’ve grasped the answers, another layer of deception is revealed. Equally compelling are the exotic settings through which the story unfolds. From hushed libraries and candlelit subterranean halls to sprawling plazas and shadowed alleys in faraway cities, the novel doubles as a globe-trotting travelogue. Brown’s eye for architectural detail and cultural nuance once again makes his settings feel like characters in their own right. More than once, I found myself jotting down names of locations, inspired to imagine journeys beyond the page. But perhaps what distinguishes The Secret of Secrets most is not just its entertainment value, but its ability to linger. Long after closing the book, I found myself revisiting its questions, its revelations, and its provocations. Brown doesn’t tie everything up neatly with a bow. Instead, he leaves you wrestling with the very ideas he’s unearthed, precisely what made The Da Vinci Code so impactful in the first place. Is this Brown’s best work since The Da Vinci Code? Unquestionably. While he has written successful novels in the years between, this one captures that same lightning-in-a-bottle alchemy of intellect, suspense, and sheer readability, all delivered at breakneck speed. It is as though Brown has circled back to his greatest strength: not merely telling a story, but unsettling the reader’s sense of reality. For fans who have been waiting for Brown to reach those heights again, The Secret of Secrets is the book we’ve been hoping for. I personally am so glad that he found that magic again. It’s a novel that thrills as much as it enlightens, entertains as much as it disturbs. And if, like me, you find yourself poring over Google searches late into the night, don’t be surprised. That is precisely the kind of spell only Dan Brown can cast. ... show more

A Prague-based masterpiece
Format: Hardcover
I went into The Secret of Secrets expecting the usual Dan Brown formula of mysterious symbols, secret societies, ancient history, a race against time, and Robert Langdon trying to put the pieces together before it’s too late. And that's pretty much what this book was but with a new question on what really is consciousness, and what if we understand it less than we think we do? Prague was the perfect setting for this kind of story, and it makes you feel like there’s a hidden world beneath everything we see. There were moments where I felt the story could have moved a little faster. Some of the scientific explanations were fascinating, while others felt a bit too much like a lecture. But as someone with a neuroscience background, I loved everything he was speculating. If you’ve read other Langdon books, you’ll recognize Dan Brown's formulafor writing, but if this is your first, it'll be a fun read. This was an entertaining read for me, and will be great if you enjoy books that make you question where science ends and mystery begins. ... show more

Robert Langdon is solving another twisted plot
Format: Kindle
Dan Brown has written another heart stopping Robert Langdon mystery. The facts that are given through Katherine's proposed book are astounding and of course the political intrigue surrounding her book. It gives you something to think about and even throughout all of the scientific explanations of what she wrote about, you were never lost. The use of cultural lore of the Golum and how he protected Sasha was fascinating. Especially after how things came out in the end. The heart stopping intrigue and never knowing what was coming next, is exactly what you expect from both Dan Brown and Robert Langdon. I loved all of the twists the book took and hope to see more in this series. ... show more

This one may just beat out THE DA VINCI CODE!
Format: Hardcover
Speechless. Fast Paced. Exciting. Cannot get enough. These are just a few ways I can describe Dan Brown's newest thriller, THE SECRET OF SECRETS. I have not completed the book just yet, as I am truly taking my time to savor every morsel of this delicious Langdon thriller. Already, I am enjoying this WAY more than ORIGIN. I truly did not like that book whatsoever and was highly disappointed. It is a toss-up which I enjoyed more between THE LOST SYMBOL and INFERNO...but this one...and it is too early to submit my verdict....but it is definitely in a tie with THE DA VINCI CODE. Here is what I like so far: 1. The reader is dropped right into the story. We do not have to read some long historical prologue to set us up for the novel. We are placed into the story and it takes off from there. 2. I love how Dan Brown takes his time to show us around. Like a tour guide so we can absorb everything. Some may not like that, but I do. 3. So far I really like the concept of this one and I cannot wait to see where it goes. 4. The book itself. I am talking about the physical book. The book feels like nothing I have ever read. It feels...well...sophisticated. The pages are soft and don't feel like other books' pages. With the book being almost 700 pages, I expected a brick. That is not the case here. This is something an electronic book misses out on. The actual PHYSICAL touch of something amazing. The publisher went all out on this as if to say, "Thank you for your patience, here is your reward." Trust me...get a physical copy of this book! Here is what I don't like: 1. While I do like the beginning of this book, it does seem formulaic 1. A tragic event. 2. A forum event where Robert is in attendance. 3. Robert gets visited by the authorities. 2. Honestly, that's it. That is the only thing I didn't like about it so far. 3. If I had to pick one other thing, it would be this. I wish Dan Brown hadn't waited so long between books. 8 years!!!! I get that it takes time to research, but at this pace, I fear I will only get 2-3 more Langdon books and that's it. If I could also say one more thing...I understand that it is frustrating to order a book and wait for months to receive it, only to find that the book cover is ripped/destroyed. It is incredibly heartbreaking...but seriously...to come on here and give the author/book a 1-star review is pathetic. Rate the story...NOT...how your book came in the mail. I will update my review later on as I progress...but I want to take this one in as long as I can. I waited 8 long years and I am going to take my time. For now...5 solid stars!!! ... show more

Fun, but over bloated and slow in places
Format: Hardcover
Another thrilling plot by Dan Brown, but this one felt like it was bloated to pad the page count. There were several chapters that felt completely unnecessary (Jonas reads in a bean bag or gets coffee, or Pavel rides the bus) and scenes that felt like were overly descriptive or repeating exposition we’ve already been told. And there were some scenes that didn’t feel fleshed out enough (the agents in the PRH office) and the ending was long drawn out. Also the twist felt weird, and the red herring actually would have made more sense. It also felt too meta - forcing PRH into the story. This novel felt like a great story trapped beneath the weight of a dull one. When it was firing, it was great; but it really drags in places. An enjoyable read but not Brown’s best work. ... show more

A novel built around substituting "consciousness" for "spirit"
Format: Kindle
As a mystery/puzzle solving novel, The Secret of Secrets does a good job of spinning an outrageous, fast-paced and entertaining yarn. If you can get past a Harvard professor in the lead, character development is excellent. Protagonists and villains are well developed - enough background information to make them real persons, without wasting a lot of writing ink. The CIA/Deep State as an institutional bad actor, though a cliché, is handled in an interestingly nuanced manner. Sorry that my criticism of this novel involves a fundamental plot spoiler. If you're a Dan Brown fan, or you just want a well crafted and written, intellectually challenging fiction read, skip the rest of this review for now and come back to it after you've finished the book. By substituting the term "consciousness" for "spirit", Dan Brown puts a new spin on traditional religious concepts. It turns out that the Secret of Secrets is that there is a pure consciousness (spirit) realm, that human consciousness is a spiritual essence inside a material brain, and that there is a possibility that individualized human consciousness can go on in the pure consciousness realm after physical death. Imagine that. A one-sentence plot summary of this book is easy. By uncovering an elaborate program of inhumane, clandestine CIA experiments to weaponize human out-of-body consciousness capabilities, over-intellectualized scientific protagonists discover what the majority of humanity has believed throughout history. Our modern day Western spiritual awareness seems to be taking a positive turn. To a point where a top tier secular thriller writer like Dan Brown could craft a best seller that hinges around "discovery" of a human/spirit consciousness realm by bona fide scientific academics. God works in mysterious ways. Maybe Brown and The Secret of Secrets can entice modern materialists to consider that people of faith may be on to timeless truth after all. ... show more

The Best of The Best
Format: Kindle
Dan Brown has outdone himself by creating an intoxicating synthesis of timeless art, arcane myths, cutting edge neuroscience and devilishly twisted spy craft; all impeccably brought to life by Robert Langdon and his equal, Dr Katherine Solomon. These two, and a cast of intense players, from the US Embassy to the Prague secret police race around trying to unravel nested puzzles within Prague which are ancient, deeply buried, and foundational to the life of every human who has ever lived-namely what is consciousness? The city of Prague with churches, castles, parks, museums, graveyards and mysteries both of light and darkness is both the setting and a moody character which imperils and protects our protagonists. Like the city, every character seems morally divided or compromised. Who, exactly, is on the good team? So expect close escapes but plenty of excellent dialogue spanning medicine, noetics, religion (of course), history, architecture, foreign policy, neurosurgery and psychiatry. I totally enjoyed the read as the complications knotted into an impenetrable Gordian knot. Only to have it patiently teased apart by the ‘Good Team.’ Read it. ... show more

A Stunner. Welcome Back, Dan Brown.
Format: Hardcover
This is a stunner, perhaps the best DB book since The Da Vinci Code. My philosophy of reviewing is that it involves three questions. What did the author set out to do? Did the author accomplish that? Was it worth doing? In the case of DB we have a specific kind of book. It has a pile-driver plot. It has interesting characters but it is not really character-driven. It is popular fiction. In addition to plot its long suits are setting and subject matter. Here we are largely in Prague, with momentary side trips to New York City. The title refers to consciousness (Langdon’s girlfriend Katherine has written a book on the subject). Consciousness is indeed the most challenging element of brain science and it includes both scientific and spiritual dimensions of immense importance. In the novel the plot is advanced by the principal fact that Katherine Solomon’s book on the subject keeps disappearing; someone does not want this book to hit the booksellers’ shelves. Who? Why? DB writes this story with a hand tied behind his back. He requires that the science all be right (this may make it somewhat fanciful, but not science fiction) and that the setting (also something strange and almost mystical) be rendered faithfully and honestly. Bottom line: this is the kind of writing which requires enormous planning and research. At the same time it must be intelligible to a broad range of readers and it must be plausible. The book succeeds on all counts. It is both the ultimate popular read and something with fascinating and important scientific/spiritual content. It is, unmistakably, a ‘Dan Brown book’. It is not Dostoevsky; nor was it meant to be. Those who write condescending reviews of it should themselves attempt to write such a book and they should be reminded that readers can enjoy and admire a wide range of genres and styles. (Yes, I wrote this review after reading a snooty review by an individual who probably longs for an audience as wide as DB’s. And, yes, there is also some puritanism at work there. Great 18thc readers like Addison and Samuel Johnson knew that ‘honest pleasure’—the kind that will neither send you to prison nor to hell—was a great desideratum in our culture, a lesson that is often lost on those who consider such pleasure beneath them.) ... show more
