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 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.

I don't know about a book that I can figure out the kill pass code in about two seconds and yet our 'code' breakers have to use the whole countdown timer.

I've been a software developer for 15 years, still am, and thought the book was fine in terms of the technical details. Granted there were some imperfections, but its fiction.

In fact, were I work they made us take a class on secure software, and the instructer commented that DF only had a slight flaw and it wasn't really an issue in terms of the story.

The story was great and unique. LOVED IT.

Maybe it's because I come from a programming background, but the startling lack of accuracy concerning software engineering, security, and computers in general make this story goofy (not the disney character)
