as Dan Brown debut novel, Digital Fortress is an amazing book! it's easy to read and understand the content of the story unlike some thriller novels that involved technology science and stuffs. and it's interesting to see some "codes" inside. i've read this since in middle school but i kinda missed the story of the cryptographer and her fiance so i bought it again ahahaha (thx God, Periplus offers my poor wallet with the best price as usual!) but it's still amazed me even if i re-read it for many times
