Digital Fortress is the best and most realistic thriller. Dan Brown has the ability to explain individual freedom and national security. Dan Brown has unleashed a surprise: a gripping story on the frontier of cyberspace. NSA cryptographer Susan Fletcher is told that their powerful code breaking machine, TRANSLTR, has encountered a code it cannot break. The code is written by a former NSA employee, Ensei Tankado, who demands that the US government admits publicly to having the TRANSLTR. If not, he will release the code that TRANSLTR can't break, thus making the code breaking machine useless. Susan Fletcher, David Becker and NSA Commander Trevor Strathmore try to find the pass-key, and at the same time they have to keep the threat a secret from the rest of the world. By the end of the book, there are so many twists and turns in the plotline.
Very Interesting techno thriller.
