Book Description

15 May 2004
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, beautiful mathematician. What she uncovers send shock waves through the corridors of power. The NSA is being held hostage - not by guns or bombs - but by a code so complex that if released would cripple U.S. intelligence. Caught in an accelerating tempest of secrecy and lies, 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.

4.0 out of 5 stars Read it in 3 days 2 Jan 2007
By Jay
I felt it started strongly with good character introductions and building people's backgrounds and reader affinity with them. There's plenty of action and some great events which are (to those who've already read Brown) now-familiar action capers with some fast changes and lots of near-misses. Plenty of fun there and it keeps you hooked.

The bit where it fell down for me was the ending, where I felt he had one eye on the action-adventure Hollywood adaption. It just seemed a bit too formulaic and there wasn't the depth. You could see what was coming - and the main bit of world-saving 'brilliance' of a genius codebreaker, well, I got it straight away, and the NSA don't want me!

3.0 out of 5 stars Good, not great 24 Oct 2004
'Digital Fortress' is Dan Brown's first book, and it happens to be the last one of his that I've read. It's clear to see that he got better the more he wrote, particularly with 'Angels and Demons' and the 'Da Vinci Code'. But that's not to say that Digital Fortress isn't enjoyable.
In this novel we follow Susan Fletcher, who is the NSA's leading cryptologist, and the whole book takes place inside just one day. In it, Fletcher is taken through a whirlwind of conspiracies and secrets involving the US government's intelligence, in particular their ability to read anyone's email. The adventure is business and personal for Fletcher, as her fiancee is brought into the equation as well. This all makes for an entertaining read. So, certainly worth looking at, but by far Dan Brown's best.

2.0 out of 5 stars Read this after Da Vinci code -- big mistake 8 April 2005
By A Customer
When Dan Brown wrote the Da Vinci code he had had three previous books as 'practice'. This is his first book and it shows. The plot is reasonable, but nothing like as compelling or page turning as say Angels and Demons. The characters are skeletal versions of characters in subsequent books and I read through it with a nagging feeling that all the jargon and constant reminders of just how brilliant the main characters are was merely covering a lack of substance and real interesting ideas. There are the charactaristic Dan Brown twists but little else.
About twenty pages before the end I began to wonder "is this it or is he saving the best for the final few pages. It was, and he wasn't.

During the reading of this book, I just couldn't stop wondering if these jerks were actually the real people who actually run the NSA. If the answer was yes, then our USofA would definitely in big trouble. The author had inevitablely gave me an impression that the whole NSA scenes inside out were just so obviously fake, since he could only imagine the tight security for entry, but once got in, he just could not provide us with more realistic pictures, so he just failed to visualize correctly and to deliver. So, what we got here from him were couple of very unprofessional, sexual harassing jerk like Hale, an egghead nerd, a very unconvincing IQ170 woman, her multi-lingualled sweetheart, an old, stress sticken No.2 guy, a steel-rimmed killer, plus several security guards outside the NSA building. Putting a Japanese American as some kind traitor, doing some personal vandetta to NSA and its personnel is still a legacy of the pathetic American syndrome orginated and still die-hard from WWII--the Asian Americans simply would not be accepted completely as other racial Americans, so, guilty until proven innocent; put them in concentration camp before they become the snitches, informers, or traitors--the (Japanese)American, even he had passed the security check to be qualified as an NSA employee, but he's doomed to be unstable, untrustworthy and would inevitablely became a traitor and sold his 'Digital Fortress' to his Japanese folks in Japan. This is a disgusting logic that made me appreciate more to the "Mercury Rising" movie. At least there were only real Americans being betrayed and killed, and all the Japanese people in that movie were just purely innocent, big dollar-spending tourists.

5.0 out of 5 stars A Great Debut 9 Aug 2004
By Scottish Dave VINE VOICE
I bought this, Dan Brown's first novel, on the strength of reading The Da Vinci Code. It's not as strong or as indepth as The Da Vinci Code but nevertheless I found it an excellent read.
It centres around code breaking and computing - there is no art history or religion in sight this time. Originally published in 1998 the computing and technology side of the book will no doubt date with time but six years on it is not too dated although I am sure experts will no doubt pick holes in some of it.
The book centres around a couple searching for a key for a newly developed code. The woman, and main character, is in her place of work, a highly secure NSA building dedicated to code breaking. Her partner is in Europe tracking down a second copy of the key which is held inside a ring.
The book is fast paced and I read it within 24 hours. I found it thoroughly ejoyable and although some of the story was a bit predictable there were enough twists to it to make it page turner.
It's not as good as The Da Vinci code but it brought to me a similar excitement when reading it. A great debut 9/10.

3.0 out of 5 stars A quick entertaining read 19 July 2004
By A Customer
A reasonably entertaining page-turner. Perfect for when you want an easy read without a complicated plot e.g. on a long flight - as long as you can forgive the use of a perfect leading couple, a few super-coincidences and glaring plot holes (the car chase down airport runway - oh, please)
The ending really disappointed as I guessed the password as soon as the clue was revealed. Surely anyone with the most basic physics education would also - and yet here we have a roomful of super-intelligent NSA-types who resort to using Google. Yeah right.
