This is an exciting and gripping story of a system administrator's life. One day, he discovers a hacker who is constantly breaking in into computer systems. When he begins to chase the hacker, he eventually finds out that it's not just some youth having fun reading other people's files. And you are going to hold your breath while following the administrator's every move. The book's well written and funny. Its philosophy is somewhat anarchist, as is usual for computer freaks, and pretty ironical towards the US government institutions. I'm glad to say that the hero, looking like just another leftist jerk in the beginning, goes through a significant attitude change when he realizes that there are countries much more evil than the United States of America.
