i just finished digital fortress. i liked it a lot, but it's not like it's real quality literature. definitely not poorly written, but you kind of always know what to expect from dan brown. every book of his is like this: some guy that has some really important information to pass on, dies right before he can pass it on, because some assassin kills him. then the main character and his really hot girl friend have to figure out what that information was by following a string of clues, and deciphering codes, and running away from bad guys.
