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.

Skip this book

If you know anything about computers, even common sense stuff, you'll laugh at Dan Brown's attempt to describe and use technology in the main plot for this story. It was so ridiculous at times that it made me want to stop listening.
I found the story line somewhat mediocre and not nearly as interesting as some of his other books.

Dan Brown's worst

The story was totally unbelievable. I have listened to and loved the other Dan Brown books from Audible (i.e. Da Vinci Code, Angels and Demons, and Deception Point). In Digital Fortress, however, I found Brown’s ignorance of computer science, cryptography and mathematics to be distracting. Since these items were intrinsic to the story line, the story did no make any sense. I am talking about more than just a few mistakes. The plot was a joke.

The narration by Paul Michael was excellent. Dan Brown writes with a great flow. The book may be worth reading if you can forget anything you know about math and physics while you read it or can embrace ignorance.

Digital Fortress (Unabridged)

Wow -it was really hard to listen to this one. I loved the Davinci Code and liked Angels & Demons but Digital Fortess was just bad. Too many boring technical details and I wished Dan Brown would stop repeating the same point over and over and over. This book really need to be trimmed down. I have never had to fast forward on a book before until this one. Definitely try the abridged verson.

Not for the technically knowledgable

The publisher says "In this fast-paced, ***plausible*** tale..." Well hardly! The plot is so rife with technical errors and inaccuracies about cryptography and computer systems that it's painful to listen to. You can't stay focused on the story, because just when you've managed to forget about the last glaring error, another is introduced. Dan Brown clearly didn't consult with any experts for this story. He confuses bits with bytes, doesn't understand how e-mail works nor what computer viruses do, and on and on. I never made it to the end of the book, and that's a first for me with one of Audible's books.

Unbearably Bad

Oh my heavens. It seems in super secret spy domes they have skylights but no emergency lighting! I think that Dan Brown was paid by the word on this one. Predictable, ignorant, and about 52 jillion timely rescues from the jaws of death. I can suspend disbelief for quite a while but this was just ridiculous.
REALLY DON"T GET THIS UNLESS YOU JUST WANT TO BURN A CREDIT OR HAVE A TEMPLATE FOR HOW NOT TO WRITE A NOVEL.
The rest of Brown's books are great, making this even more of a let down.

Save a credit

My my, this had to be one of the worst reads ever. I usually don’t write reviews, but this book was so bad I just had to let you know. I agree with other readers that the climactic puzzle in the book was so obvious, I figured it out right after reading the riddle, and it took these so called NSA masterminds chapter after chapter to figure it out. The entire book was so predictable that I had the secret villain pegged within the first few chapters. And finally, two of the supporting characters, Midge and Jabba were so irritating, I once blurted out, “shut up!” while listening to their banter, and I got a few stares. Take my advice, save your credit. It’s hard to believe this is from the guy who wrote Di Vinci Code.

Entertaining listen

Brown knows how to write a good page-turner. This one is typically far-fetched and intriguing at the same time. I found that it got tiresome after a while and wished it would have ended sooner, but it is an easy and entertaining listen.

I should have heeded the one-star reviews

I enjoyed DaVinci Code and even Deception Point, both of which required some reasonable 'suspension of disbelief.' But this preposterous mess requires something more--maybe 'suspension of conscious thought.' I couldn't quite do it, but the "brilliant" characters in the book seemed to have it down pat. They took for-bloody-ever to work out the simplest puzzles in the plot.

I won't go on. I was warned by the 1-star reviews below, but I decided to give it a whirl anyway. I should have heeded the warnings. Avoid this crock! (And if you do happen to read or listen to this book anyway, please take the description of doings at NSA with a boxcar of salt. Brown's descriptions are nonsense made up to support his awful plot.)

A Predictable Disappointment

This book is extremely predictable. The worse part of my whole experience with this book was that I figured out the ending well before the main characters, who are supposed to be math geniuses and college professors. It was sort of insulting. The ending was just the topper of several hours of totally predictable, brain-dead strings of unreal coincidence and shallow characters. I made it though only because I payed for it and felt obligated. His other books are much better, so please skip this one.

Not a favorite

I, like many other reviewers, enjoyed DaVinci Code and Angels and Demons. This book, though, fell short. As another reviewer pointed out, the female protagonist is some male fantasy characature. The ending is predictable to the point that the listener figures it out before the characters.

I did like the original premise, but it could have been handled much better.

Good but Dan Browns worst!

....well it's not trendy to admit liking Dan Brown (or anyone who's had massive success), but I love his books. That admitted, this is probably my least favourite of his excellent thrillers. Well worth getting, but check out all the others first!

avoid if you know anything about cryptography

if if weren't for Dan Brown's attempts at technical details it would be quite a good story. in fact the amusingly incorrect babble about cryptography and security aren't really needed to tell the story but if you know even a little about either the errors are huge and jarring.

Not his best

I like the pace of Dan Browns books but I did feel that this story line was not as good as his others.
It still kept me entertained but was a bit predictable.

Worst Dan Brown

Dan took what could have been a promising storyline and turned it into an implausible ridiculous yarn. Utter rubbish.
Did listen to entire story and it became more ridiculous all the way through.

If updated for today would be quite topical

Would you consider the audio edition of Digital Fortress to be better than the print version?

I found the audiobook well read and good use of different voices

What was the most interesting aspect of this story? The least interesting?

The storyline in span was the mode interesting was a bit of a bread crumb investigation with one person leading to another bit frustration but kept the pace up.

Was this a book you wanted to listen to all in one sitting?

Yes I listen to this book pretty quickly

Any additional comments?

The story is good and quite interesting, being from an IT background some of the technical aspects were not quite right but not too back. You may feel a bit frustrated by the higher up managers in this story as they constantly don't listen to their staff but I guess that adds to the drama?

Glad it's finished

I found the plot interesting but at times I thought I was listening to an episode of Scooby-doo, and found it both repetitive and annoying and had no interest in the characters at all and was glad when it was all over. Which was a shame as I had read deception point and enjoyed it as an easy holiday read.
