This an alternate cover for 9780552151696

When the NSA's invincible code-breaking machine encounters a mysterious code it cannot break, the agency calls its head cryptographer, Susan Fletcher, a brilliant and beautiful mathematician. What she uncovers sends shock waves through the corridors of power. The NSA is being held hostage...not by guns or bombs, but by a code so ingeniously complex that if released it would cripple U.S. intelligence.

Caught in an accelerating tempest of secrecy and lies, Susan Fletcher battles to save the agency she believes in. Betrayed on all sides, she finds herself fighting not only for her country but for her life, and in the end, for the life of the man she loves.

From the underground hallways of power to the skyscrapers of Tokyo to the towering cathedrals of Spain, a desperate race unfolds. It is a battle for survival--a crucial bid to destroy a creation of inconceivable genius...an impregnable code-writing formula that threatens to obliterate the post-cold war balance of power. Forever.

Dan Brown is the author of numerous #1 bestselling novels, including The Da Vinci Code, which has become one of the best selling novels of all time as well as the subject of intellectual debate among readers and scholars. Brown's novels are published in 56 languages around the world with over 200 million copies in print.

In 2005, Brown was named one of the 100 Most Influential People in the World by TIME Magazine, whose editors credited him with “keeping the publishing industry afloat; renewed interest in Leonardo da Vinci and early Christian history; spiking tourism to Paris and Rome; a growing membership in secret societies; the ire of Cardinals in Rome; eight books denying the claims of the novel and seven guides to read along with it; a flood of historical thrillers; and a major motion picture franchise.”

The son of a mathematics teacher and a church organist, Brown was raised on a prep school campus where he developed a fascination with the paradoxical interplay between science and religion. These themes eventually formed the backdrop for his books. He is a graduate of Amherst College and Phillips Exeter Academy, where he later returned to teach English before focusing his attention full time to writing. He lives in New England with his yellow lab, Winston.

Brown's latest novel, Origin, explores two of the fundamental questions of humankind: Where do we come from? Where are we going?

This is the book that I liked the least among the six that I have read by Brown.

The plot seemed a bit weak in some parts, and its central theme, which involves codes, algorithms, and all the high-tech aspects of computers, couldn't really seem as impressive to me as it might have seemed twenty years ago when I regarded the monitor next to my PC as a superior deity.

It's entertaining as a read, but that's about it.

Overall, while it has its moments, it doesn't quite measure up to some of his other works. The story could have been more engaging and the technological elements could have been presented in a more captivating way.

Perhaps if I had read it at a different time in my life, I might have had a different perspective. However, as it stands, it's just an okay read that didn't leave a lasting impression on me.

The story was first published in 1998.

Well, what's the problem?

There are no problems at all.

The simple problem is that it talks about technologies on the Internet,

such as programming, hacking, and codes.

The electronic world makes you feel that we are dealing with a computer.

It used to be radio and television.

I stopped and read this story like this once.

I don't understand.

The man says important and clear things. He knows how to talk well about what?

Because Dan Brown doesn't write to make a living hard.

The man writes and does long research for years.

Well, for this story,

about the Internet in 1998,

what's left?

A lovely trick that fooled me at the end of the story, and that's it, and our parents are completely fine and everyone knows his head from the man.

Faithful, at the last page,

he gives you a lovely gift.

128 - 10 - 93 - 85 - 10 - 128 - 98 - 112 - 6 - 6 - 25 - 126 - 39 - 1 - 68 - 78

A code for you.

I and a friend of mine, for a while, tried to understand the religion.

And the other finally convinced me, saying, assume we have two factors, and we solve it.

And the other,

it comes out.

It was done, praise be to God.

How do you feel?

: )

I discovered at that time how it was solved and I was turning around it.

The solution was simple, by God.

There is nothing for us.

A story of the world of networks, the Internet, and hackers,

and all the people who are dealing with each other.

Dan Brown hits the mark here.

Trash

With impossible computer concepts, a story flatter than a dead line, and overly clichéd characters, to say it's trash is an understatement. The so-called "plot" seems to be cobbled together without any real thought or creativity. The computer concepts presented are not only far-fetched but also lack any real depth or coherence. The characters are one-dimensional and predictable, failing to engage the reader or viewer on any meaningful level. It's as if the creators simply went through the motions, relying on tired tropes and stereotypes instead of trying to come up with something original and engaging. In short, this is a prime example of why some works should never see the light of day. It's a waste of time and resources, and a disappointment to anyone who was hoping for something better.

A truly remarkable story and one of the best police novels in the world.

Its style is extremely unique as each chapter ends with a great surprise that contradicts what you read at the beginning.

It makes you extremely eager to know what will happen and if you take a little guess and try to predict the course of events based on your in-depth reading, you will not succeed because the author's style is very exciting and keeps you in a state of confusion until the last page, and even the last line of the story is very exciting and highly anticipated.

This story has a special charm that attracts readers and makes them unable to put it down until they finish reading the whole thing. It is a must-read for those who love police novels and exciting stories.

There's a reason why everyone talks about The DaVinci Code and not about this book. I have no idea what that reason would be. I thought Angels & Demons was mediocre, so I never bothered to read The DaVinci Code. Anyway, one day I was bored and a copy of this was sitting at the library for a quarter. I thought, "WTF, mate, I'll give it a go."


The first page of chapter 1 starts with Susan Fletcher waking from a romantic dream to the ringing of the telephone. "Susan, it's David. Did I wake you?" She smiled, rolling over in bed. "I was just dreaming of you. Come over and play." He laughed. "It's still dark out." "Mmm." She moaned sensuously. "Then definitely come over and play. We can sleep in before we head north."


That is not a transcription typo, or the manifestation of my unfocused rage. It really does read '"Mmm." She moaned sensuously.' Please feel free to vomit if you need to; I'll wait.


David then proceeds to postpone their plans to celebrate their six-month engagement due to something hush-hush, like maybe his being a big homo. C'mon, what sort of man is going to pass up some sweet, sweet lovin' from his woman before disappearing on a mystery mission? The kind who likes other men, that's what kind. A handful of pages later, it becomes clear that Dan Brown has read too many Clive Cussler novels as we're treated to a description of David Becker. "Becker was dark--a rugged, youthful thirty-five with sharp green eyes and a wit to match. His strong jaw and taut features reminded Susan of carved marble. Over six feet tall, Becker moved across a squash court faster than any of his colleagues could comprehend. After soundly beating his opponent, he would cool off by dousing his head in a drinking fountain and soaking his tuft of thick, black hair. Then, still dripping, he'd treat his opponent to a fruit shake and a bagel."


Is it just me or does this read like Dan Brown was typing this with one hand? Why does Mr. Stud have the same initials as the author? Why would anyone want a sharp green wit? And is 'fruit shake' some sort of code for a handy? Is that why he is still dripping?


So then, after all this ran through my immature little mind, I remembered I had other books to read--books that didn't suck horrifically within the first ten pages. Yay for other books! Oh, and I sold it to a used book shop for a dollar, so it was worth the quarter. Yay for used book shops!

Dan Brown's unique style that I think I have become accustomed to is present in the cliffhanger at the end of the novel.

The events in the digital fortress unfold within a single day, full of excitement. It's the hunt game that characterizes Dan Brown's style. Just when you think it's about to end, a series of other events emerge, increasing the complexity of the story's plot.

I don't think there are many books like Dan Brown's that can make me smile one moment because I think I've solved the mystery, and then frown the next because I feel that the author, while narrating, has planned to disappoint the readers and push them to use their minds more. This is one of those novels that made me laugh sarcastically at the end when I realized that most of my guesses were not even close to the truth, and also because of the relaxation that the events brought me.

Wonderful as always, Dan Brown.

Oh Dan Brown, how I love to hate you.

It seems to be a universal truth that when you have exhausted all the books you brought with you, it becomes nearly impossible to find decent reading material wherever you are.

Shamefully, I have actually read most of his books. I read "Angels and Demons" because someone recommended it to me. Although I found his writing to be extraordinarily poor, I was intrigued by the story enough to overlook that fact. I failed to guess the ending, and it presented some fascinating ideas about history. I read "The Da Vinci Code" because everyone was reading it and because I liked "Angels and Demons". The writing in "The Da Vinci Code" was equally bad, but I noticed many similarities in the plots of the two novels. However, it was still an entertaining read, so I decided to forgive it.

Then, on my way to Costa Rica, I realized that I didn't bring enough books for the plane ride. I went to the bookstore in Charlotte, North Carolina, and picked up "Deception Point", yet another Dan Brown masterpiece. The plot of this book was like "The Da Vinci Code Goes Arctic". That's when I realized that Dan Brown had come up with one good plot and was simply recycling it over and over again.

Even so, faced with the options of "Rich Dad, Poor Dad" or "He's Just Not In To You", I picked up "Digital Fortress". I do think his writing is improving, but I had the ending of the book figured out within the first ten pages. I didn't even have to read the ending first to know what was going to happen. Maybe I'll register "Digital Fortress" on BookCrossing and send it out into the world.

Kumbrmjah wa kqar'ah tmkn hth al-'amal mn al-tasallul lil-'aql wa al-qalb lathra'ah al-'ilmi wal-lughawi...


This work, being programmed and readable, is able to infiltrate the mind and heart with its scientific and linguistic treasures...


It is a beautiful and expected work from Dan Brown. His works are always known for their captivating plots, rich historical and cultural backgrounds, and thought-provoking themes. This particular work seems to continue in the same vein, promising to take readers on an exciting journey through the realms of knowledge and mystery. Whether it's the exploration of scientific concepts or the unraveling of linguistic puzzles, Dan Brown has a talent for engaging his audience and keeping them on the edge of their seats. We can't wait to see what this new work has in store for us.
