I was reminded today of an excellent non-fiction e-book I read about a year ago and had forgotten until recently. It's a great yarn called Underground written by Suelette Dreyfus. "Tales of hacking, madness and obsession on the electronic frontier" is indeed a perfect description of this book.
The story follows several computer hackers in the US, UK, Australia and Germany back in the days of old computers and BBS systems. If you're thinking to yourself that a non-fiction book about old time hackers sounds incredibly boring I'm here to tell you that you're wrong!
Now I'm not sure how I came across this book, but after getting into the story was very glad I did. I was amazed at the flow of the story and how interested I became in the characters. Suelette's writing voice is nicely transparent to the story itself, and the background information seems very well researched. I was amazed at how hard it was to put this nearly 500 page book down. In fact, after reading the book I sent in my $12... it was that good!
So, rather than go on about the book, I'll just direct you to the download page where you can grab a copy in one of many different formats, including Palm Reader, iSilo, Doc and Plucker to name but a few. Give this book a read -- I'm confident that you'll enjoy it.
