Writing a book on hacking, computer security, and so forth is hard. When this was written, back in 1997, it was surely even harder, as the general audience this book is aimed at was presumably less familiar with the technical details of "cyberspace." Dreyfus manages to make it work and capture a snapshot of the feel behind some of the (primarily Australian) hackers she features in the book.
I read this from a PDF that's freely available on the book's website; it was presented in a fixed-width, typewriter-seeming font -- the sort of font that you'd use to read most electronic text from the 1990s, and eschewed much typography or layout (again, like you were reading an ASCII text from that period). This may have made it worse, because Dreyfus kept interrupting her own timeline to include anecdotes or brief timejumps about the subject of each chapter. But with no sign that the timejump occurred, the writing felt disjoint and bizarre, irrelevant details complicating what should be straightforward description of what happened.
I read the first 200 pages or so quickly, before it got to the chapter on Assange ("Mendax"). He apparently helped edit the text (he is listed as a contributor here on Goodreads); it was there that, whether it was simply seeing how the text glissed over attributes that more recent profiles of Assange have focused on, or wondering how much of this chapter has been glamorized, that I felt like it became a captive to the "hacker" view.
In the end, I finished but was left feeling that the book glossed past things, and the writing itself left me down. I probably wouldn't recommend it -- Michelle Slatalla's Masters of Deception was written at around the same time, and took a similarly fairly sympathetic view of its characters, but is much better written.
