An exciting thriller, difficult to put down. Mystery about breaking a code to save the NSA database. Since the book was written in 1998, some of the "state-of-the art" technology is now commonplace. But the story is still exciting, and full of surprises through the end. A fun, entertaining read. ( )

Good thing I bought my copy at the Thrift store. On page 23 you find out the Commander has a thing for his golden girl. No surprise when he sends her professor boyfriend on a mission he plans will be the death of him. Page 85 graphically gives away the pass-key. The only reason to finish the book is to find out what the boyfriend meant by "without wax." Could have Googled for that. The book was copywrited in 1998 but must have been written a good deal earlier if Mr. Brown thought people didn't know about the NSA or use better security than this on their own job. When was the last time you were allowed to use a password that wasn't a minimum of 6 alpha-numeric characters with a combination of upper and lower case letters? Who hires someone that hates your agency and then lets him come in on the weekend unsupervised? This plot is way to simple for someone who devoured all the Sherlock Holmes books in grade school instead of the easy readers they call YA books now. ( )

Les personnages ont une épaisseur psychologique de la taille d'un papier à cigarette. On trouvera certainement plus profond dans la collection Harlequin.

Dan Brown ne maîtrise pas son sujet en ce qui concerne l'informatique et la cryptologie. C'est aussi crédible que ces films où les ordinateurs explosent pour montrer qu'ils ne fonctionnent pas. L'intrigue est faible et l'idéologie nauséabonde.

Tout est mauvais la dedans il n'y a rien à sauver. Mon appréciation à 1/2 étoile est due à l'impossibilité de mettre des notes négatives dans Library Thing ( )

What a load of cobblers…NSA expert fails to see connection between N Dakota and ... ( )

Awful. ( )

Clearly Dan Brown uses the same formula for this book as for Da Vinci Code. What is there to say, written for an audience who likes quick actions, with shallow characters, and, again for someone who has read the Da Vinci Code a plot so predictable the only reason I finished this book was because I was on a bus and had nothing else to read. ( )

I thoroughly enjoy Dan Brown's style of writing. This book was hard to put down. Just when you thought you had something figured out, a new surprise was around the corner. It was as gorey or graphic as the DaVinci Code or Angels and Demons, so it was more to my liking. :) ( )

Dan Brown is a master storyteller, exciting plot, fast-paced, and suspenseful with the formulaic twists and turns. This guy is just so into codes and it's very interesting. ( )

Enjoyable and fun read. ( )

Het National Security Agency (NSA) breekt vele vijandige codes, maar dan ontdekken ze een code die niet te kraken is. Zal het codekraakster Susan Fletcher lukken om op tijd de code te kraken? ( )

This is about a top secrey government agency that cracks codes. There is a new code that is unbreakable, and everybody is racing to solve it. Susan Fletcher, the top cryptographer, is close to the head of NSA, but what does she really mean to him? Will David find the ring, and save the information in the data base? Read the book to find out who will solve the mystery first, and who is responsible for this crime. ( )

Digital Fortress is a thrilled read. To me it came off as a completely unexpected conclusion in the end. Not many books have that these days, do they? One thing that excites me about Dan Browns books is the fact that he brings historical facts into his fictive novels which he is able to back up. ( )

Read it on the beach. Short book. If you like computers and melodrama, this book fits the description. ( )

o pior livro do autor, enredo muito lento e sem interesse. personagens sem chama. ( )

Dan Brown is great at mysteries and taking your breathe away at the very end with a crazy ending that you could never have thought up of in your lifetime. Although it is not a very well known book of his, if you like mystery book, you will surely enjoy this one. ( )

Yay for nerds! An exhilarating ride from start to finish.

This is the first time I've read anything by Dan Brown and I have to admit that I'm not sure why so many people love his books. In Digital Fortress, the suspense is enough to keep you glued, although a lot of the plot twists are predictable. In general, the characters are flat and/or stereotypical and mostly not people who the reader engages with and therefore cares what happens to them. In the beginning of the book, there is a fair amount of exposition about the National Security Agency and the technology employed there, which is not the most interesting thing to read, especially in a work of fiction, although it is necessary for the reader to understand the rest of the book. However, Brown has a habit of restating an idea a few lines later with only slightly different wording, which becomes annoying after a while. The end of the book contains a section where some of the most brilliant minds are gathered together and cannot figure out the simplest things, which is maddeningly frustrating to read. Overall, this book is okay for a beach read or something similar, but not anything of significance. ( )

This was, to be blunt, complete pants. A really stupid story about a central US computer/code breaker, with a ridiculous number of plot holes, making the whole thing pointless. One to avoid. ( )

once again a book that had such good potential is ruined by Dan browns awful writing style. For all the character development, if they turn this into a movie they may as well use stickmen. This book is a better story than any of his other novels but it is barely readable because of poor penmenship. I must admit by the time i finished it i was paying no attention, but i sincerly doubt that i missed anything good. ( )

I'm embarrassed I have this book after thinking the "Da Vinci Code" and "Angels and Demons" were both overrated. I recall being out of reading material in a small airport with limited selections and hoping for the best. As with other Brown books, character development is minimal and the writing is weak. It's like reading a Hollywood movie - and in this case, a pretty bad one. ( )

Amateurish, with a nonsensical plot that still manages to be predictable, careless characterizations featuring NSA experts that, like the author, know absolutely nothing about computers or cryptology (not even the difference between 'codes' and 'cyphers'). If this had been the first Dan Brown book I'd read, you'd NEVER have gotten me to read the enjoyable Angels and Demons (or the less enjoyable but more controversial Da Vinci Code). ( )

Not bad as in "don't buy or read" but much more predictable than the other books Dan Brown wrote. ( )

Y - A - W - N. I suspected he borrowed Hale from the Nedry character in Jurassic Park, and the rest of it was formulaic and really, REALLY dull. Forget "Airplane Thriller", it wasn't even a good "Commuter Rail thriller" - I fell asleep in the middle of it and almost missed my stop.
