I just finished reading The Cuckoo's Egg today it's about security in the days of Arpanet et al (1986).

It was a little goofy and it has a lot of human interest stuff in it to make it more of a story, but I liked it.

I can't remember life before everyone was on dialup Internet, so it was very informative to me.

pg shows up as a student in a tiny aside at the very end!
