Digital Fortress is Dan Brown’s thriller for geeks. The NSA has a unstoppable code-breaking machine used to protect the US. When an unbreakable code comes along, Susan Fletcher is called in. Fletcher is not only a beautiful mathematician, but also the head cryptographer for the NSA. She finds that the NSA is a hostage, and her fiance is in danger.
While exciting at times, Digital Fortress is pretty nerdy. A couple good surprises help the story along. But overall, Digital Fortress is not the thriller I hoped it would be.
