I read this book about 20 years ago when I was in high school. It was one of my favorite books at the time. I think I read it 3 times during my high school years. It was a great read at the time.
I haven't read it recently but anyone that lived experienced technology of the 80s/90s or wants a realistic feel for what it was like should read this.
It's a great story about how a guy from Berkley (I think) tracked down a hacker. I don't remember the specifics but it was very War Games-esque but based in reality.
