This was my least favorite of brown’s books but even so it was still okay. The digital fortress is the NSA’s super-duper computer system that can crack any code currently known. When it comes across an unbreakable code, trouble starts. As someone who is into computers, it’s tough for me to read books that seem to be written by people who only sort of understand technology. I’m sure brown has able researchers, but a lot of the little plot hooks in this story didn’t really ring true to me. He is writing about people who spend their lives working with computers and yet they make dumb little mistakes that were tough to reconcile with what we know to be true about the NSA. Over all this was the weakest of Brown’s books and yet still a pretty engaging romp in the same style as the other ones.
