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.
Another great piece of work by Dan Brown. The book has been well read which makes it all the more enjoyable.
