The listing, Digital Fortress by Dan Brown (#1 NY Times Best selling author of Da Vinci Code) has ended.

In superstar author Dan Brown's gripping debut, a disgruntled former employee cripples the computer system of the National Security Agency with a seemingly unbreakable algorithmic code. As the computer locks up its circuits trying to decipher the encryption, mathematician Susan Fletcher, the NSA's resident code expert is called on to expedite the process. Unfortunately, Fletcher soon discovers that, by unlocking the algorithm, the computer will actually expose its precious database to invasion by hackers around the world. When the angry employee who unleashed the code turns up dead, it becomes apparent that larger forces are at work, and the security of the entire nation is at stake.
When Dan Brown's later book, THE DA VINCI CODE, became one of the most lucrative books of all time, DIGITAL FORTRESS soon joined it on bestseller lists.
