Publisher's Summary

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 sends 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 it 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.

"Exciting...will rivet cyber-minded readers." (Booklist)

You've got to be kidding

I wanted to strangle the characters. This can't the same guy that wrote the DaVinci Code. If you like to hate characters and find fault in detail...read this book. I'd give this no stars but I can't reset.

Bad Computer Science

This novel held some promise till it got close to the end. Then it turned really bad. As some other reviewers noted, the science is just bad. Perhaps if I was not a software developer I could have been fooled. I'll mention that I am a Dan Brown fan. I loved Angels and Demons as well as Davinci Code. This novel felt like it was written by someone else though. At the end I felt like I wsted my time.

Brown would have failed my 7th grade science class

The story is good at times but completely unconvincing at others. Brown needs a better understanding of both computers and science. There was at least one basic science error that my 7th grade students would have spotted in a minute. The character of Susan was also rather unconvincing as her role as a code breaker. Otherwise it was an entertaining listen, as long as you don't examine it too hard.

digital fortress

Of all the dan brown novels other than the davinci code, I liked this one the best. This is a great one for people into computers and conspiracy theories. It is pretty full on the whole time. A great listen

technological marvel, spellbinding

This is another of Dan's great works... suspense, thrill, moving, and an excellent progression thru the whole thing! Lots of technology, and a long climactic ending keep you drawn in thru the whole thing! Whether or not it's factual I don't know, but he writes like it is, and because off that, the story builds on its own foundations. I would love to read more stuff like this.

Disappointing

After hearing good things about this book, I was disappointed after actually hearing it. The computer jargon is hopelessly out-of-date and incorrect in easily correctable ways. Dan Brown should have his works reviewed by those who understand the technology he is describing. While some of the central plot themes are interesting, I found the ending predictable and very drawn out. When I can guess ahead of the characters, it is a very bad sign. Toward the end, I begged the book to pick up the pace. It didn't. Like other Brown books, there were plot elements inserted without motivation for his convenience. Example: Why would the NSA put Guardian in front of Translator rather than in front of their central database? Or why not use two Guardians? I hope the real NSA is not as stupid. If the NSA in the book had done the logical thing, then the plot elements that relied on Guardian being in front of Translator would have to be reworked. I'd skip this book.

total waste

The DaVinci code must have been a fluke because since I have 2 other books by ths author and they stink like molding cabbage baking in the still air of the arizona desert. It dragged on forever. The las hour and a half was the end scene in slo-motion description. PLUS the narrator constantly make a smacking/swallowing noise during his reading. uck

SANS Security Primer meets Angels and Demons

I have only read up to chapter 23 and so far am thrilled with what i have heard so far. This novel is both entertaining and educational!

Would be aspiring hackers can learn a lot of technics just by following the fast paced twists and turns of the drama.

Cant wait to get to the ending of the novel!

It's Not Bad

Little too pricey for the amount of times I was bored. Interesting read tho. Maybe a low 4 for my rating. This author can do better. I guess I expected more.

Better ending:

Susan wakes up at the end to find a note from david explaining that he is in a gay relationship with the commander who she thought was in love with her. The five digit password was actually "DAVID". David and the commander both skip off into the sunset hand in hand.
