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, because I thought Angels & Demons was mediocre so I never bothered to read the The DaVinci Code. Anyway, I was bored and a copy of this was sitting at the library for a quarter and 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?"

One could already see the direction Brown would go with his recipe of conspiring the heck out of the literary world with his first work.

Not as good as Angels and Demons and The da Vinci code, but not as bad as The lost symbol, Digital fortress is the career start of a novelist who used good oldfashioned knowledge in a unique, new way on his way to literary immortality.

The art part is small in this one, as it´s more of a technothriller than the more blockbuster mystery high speed pursuit style

I work in the Information Technology field so relating to this book was easy for me. I don’t know anything about NSA (National Security Agency) and how they operate but I know stuff like encryption, algorithm, anagram, computer virus, code-breaking, etc. So, this book glued me from start to finish. My officemate has been telling me that this is his favorite Dan Brown book. He said that since I’ve read all his 4 other novels, The Da Vinci Code, Angels and Demons, Deception Point (all 3 stars, i.e ...more

Digital Fortress, Dan Brown

Digital Fortress is a techno-thriller novel written by American author Dan Brown and published in 1998 by St. Martin's Press.

The book explores the theme of government surveillance of electronically stored information on the private lives of citizens, and the possible civil liberties and ethical implications of using such technology.

My book group chose this book and I will never forgive them.

I’ve never read anything by Dan Brown. He doesn’t write my type of fiction, so while I was aware that he’s a huge success, I never bothered to pick any of his books up because I knew I wouldn’t be interested.

What I didn’t know is how much of a shit writer he is.

I’m sure he cries into a giant pile of money every single time someone tells him that.

Digital Fortress is about the government and secrecy. Susan Fletcher works for a super top
Dan Brown is not just Da Vinci Code! This is a pretty good cyber-thriller. It resonates well in a world where data security and hacking are a part of the daily news. Check it out if you are a fan of fast paced thrillers with lots of suspense. (It has short chapters, too, which I like a lot)

Spine wrecking thriller. Never could I put my popcorn down.

The topic is quite interesting & having an author perfectly fit the shoes of one so revered (talking, of course about the late great Michael Crichton) is truly magnificent, in my book. This thriller is fast (hooray!) & riveting. It is relevant to modern times & some reviewers have gone as far as calling it plausible.

But it must be said that its an adventure less compelling than The Da Vinci Code, even more contrived; devoid of interesting characters but plagued with dead ends, ineffective repeti

I learned that Dan Brown is a bad writer and I will never read any of his other books. I also am upset at my friend for recommending me this book.

In short, the book is a bad novel, and a very bad novel if you know anything about math / cryptography.
Not only the technical errors were appalling, but the writing style itself is mediocre.

WARNING: spoiler here.

There is a scene where the heads of NSA along with some of the smartest people on Earth were trying to solve a riddle left by the bad guy as a

No matter what people want to say about Dan Brown or his books or hatred towards him you got to admire the fact that what he brings to the table no one else does.

This was the book which brought me to the beautiful world of books. Before reading this book I though reading was a bit cissy and a waste of time since everything is fictional, why not better read some spiritual/self help and knowledge books. After reading this book everything changed, I started to read more and more fiction and today b

I'm not sure what to believe after reading this book. I've always liked Dan Brown's books because he writes so realistically, using big words to belittle readers about how little they know.
Or so I thought.
After reading this book, I did a little snooping of my own (OK, those were big words too, I just used Google) and realised that most of the technology, computers and cool machinery did not exist. In fact, Goodreads was an excellent source of information of unhappy reviewers tearing down this bo

I don't even remember what this one is about. There's a CIA computer technician, and all I can remember about her is the scene where a security guard is ogling her sweet, sweet ass and wondering in bafflement how a woman with a 192 IQ could be so damn fuckable. Also, I'm pretty sure she saves the world with computers, but we're not supposed to care because she does it while her shirt is partially unbuttoned. She may have gotten wet at some point, too.

What a ride! All I can say is Dan Brown is one hell of a thriller writer! I will admit that this type of book is not really my cup of tea (I picked it up on a whim) because I’m more of a fantasy/ paranormal fan and this was far from that. I also will admit I nearly didn’t read this and nearly sent it back to the library so I could have more fantasy books. I’m so glad I thought otherwise!

This is my first Dan Brown book and as cliche goes this would surely not be my last! Originally, I started reading this last May but never got around to finishing it after I stopped at Chapter 20, and I must say that despite of the 5-month hiatus, I could still remember the details vividly. This was a wildly entertaining and the kind of info-dumpy book that I'm eager to read. The way Dan Brown paces the whole plot with (surprisingly!) digestible chapters r

Reading Dan Brown books is a bit like watching porn. Mildly enjoyable at the time, but not really something you'd like your friends or family to know about.

Digital Fortress starts as it means to go on, with two-dimensional characters in a whirlwind of mystery and action. The cast never evolves beyond cardboard cut-out level, but the plot does pick up through various levels of incredulity and intrigue to a climax that ends up shallow and disappointing, leaving the reader feeling cheap and cheated

Oh Dan Brown, how I love to hate you. It seems a universal truth that when you have run out of all of the books to read that you’ve brought with you, it is impossible to find decent reading material wherever you are.

Shamefully, I’ve actually read most of his books. I read Angels and Demons because someone recommended it to me. Though I found his writing to be extraordinarily poor, I found the story to be engaging enough to overlook that fact. I didn’t guess the ending, and it posited some fasci

What would happen if every nation and person in the would, with a computer, could access every top secret file of the government? This is what Susan Fletcher and David Becker have to prevent in Digital Fortress by Dan Brown. With a lot of action and suspense Digital Fortress is a book for anyone who likes action.

Dan Brown wrote many other action novels. I have read all of them and this novel is just as good of a read as the rest. This novel is written in the same style as all the others. Leaving

This is one of the two stand alone novels authored by Dan Brown; other being the Deception Point. Both are of the science fiction genre. But no matter on what genre Dan Brown writes, one thing you can be certain to find; and that is the use of codes and puzzles.
With his unique use of codes and puzzles he creates a wonderful mystery, where the reader is taken on a suspenseful journey. I have always loved Dan's ability in keeping the reader on the edge and making him too run against the time to s

Here’s the problem: Digital Fortress has a good plot, but it’s filled with weak characters. I really liked the plot. A disgruntled NSA employee develops an unbreakable encryption program (the Digital Fortress) and threatens to give both the encryption program and the key (which is buried in the program) away on the Internet. If the bad guys gain access to the key, they will be able to communicate without fear of the NSA decrypting their messages. This throws the NSA into a panic – as it should – ...more

Based upon how very little I'd heard about Dan Brown's two non-Robert Langdon books, I went into this one with very low expectations. However, Digital Fortress is a fairly well-written and entertaining novel. The main storyline is based upon a hush-hush operation within the NSA to obtain and or destroy the only existing copies of a pass-key that, if made public, could enable the use of an encryption program that would create coded messages that would be entirely unbreakable thereby rendering the ...more

I picked up this Dan Brown’s debut novel after enjoying he’s Robert Langdon series, it’s exactly what you’d expect with quick fast paced chapters and an intriguing mystery - this time digital codes and computers.

It’s a fun thriller than keeps you interested, I did enjoy it but missed that Harvard professors presence.
I’ll have to try he’s other standalone adventure - Deception Point.

I think this was possibly my least favorite book by Brown. It lacked a certain something. Maybe it's just because I'm not that savvy in the things he wrote about, but I choose to think otherwise. He should stick to what he does best, historical mystery.

Susan Fletcher was the head of NSA's Cryptography Division while Becker was a university professor who helped government agencies with translation other than his full time job.

NSA built a new code decipher TRANSLTR worth $2 Billion but kept it as a secret. They recieved a code which was indecipherable even by TRANSLTR. The code was sent in by Ensei Tankado who was an ex-employee of NSA. He was thrown out of the organization because he always broke rules.

Definitely a fast-paced book that was breathtaking at times which took me into the world of of cyberism and national intelligence. What I love about this book was that the heroine, Susan, was a female. Not only that, but she was one of the important asset to breaking the code.

As we may know or realize (or not), our government has many top secret infos and files with top-of-the-line technologies, firewalls, and so on. Imagine when someone was blackmailing the agency and was on the verge of exposi

Not a bad debut. Inaccurate and slanderous portrayal of Spain aside, this was pretty good, a fun ride, a little immature but really enjoyable. Considering Brown set out to best Sidney Sheldon, one of SS's books impelled him to start writing his own, to pen a "better" thriller. I'd say he achieved his aim not sure if that's a victory. DB is horrendous with background. Say what you will about Sheldon but he got his research right, well most of it anyway.
