Digital Fortress is an early thriller novel by Dan Brown, dating back to 1998. It preceded the much more famous Angels and Demons and The Da Vinci Code by a few years. The story centers around NSA cryptographer Susan Fletcher and her boss Trevor Strathmore. They are tasked with破解 the mystery of a new encryption algorithm called Digital Fortress, which is said to be unbreakable, even with the NSA's powerful code-breaking supercomputer, TRANSLTR. There is a murder involved, and a perilous journey across the globe to obtain the pass-key for decoding Digital Fortress. While the story is somewhat predictable, it's not all bad.
Susan's fiancé, professor David Becker, is clearly the early prototype for Brown's most renowned protagonist, Robert Langdon. He is almost an exact replica of an unsuspecting university professor who is unwillingly thrust into crazy and dangerous adventures around the world. Both the protagonist and the basic plot of every Robert Langdon book bear a number of similarities to Digital Fortress. From this, I've learned that Brown's works are quite formulaic, similar to those of Dean Koontz. Additionally, I'm not sure if it's just my edition (the one pictured with the green cover and image of the eyes at the top), but the editing in this book is some of the worst I've ever seen. There are numerous missing words, sentences starting with lowercase letters, misspellings, and more, making it seem like the book wasn't edited at all.
Despite these issues, Digital Fortress isn't actually that bad. It does drag at times, and it's so predictable that I was able to guess the answer to the major puzzle of the book a few pages before the characters did. However, it does have its moments. I wouldn't necessarily recommend it, but it's a decent read.
