If you are looking for a fun book, but with some good computer technology (UNIX :)), and a lot of suspense, you should pick up a copy of The Cuckoo's Egg, by Clifford Stoll. This book is an easy read, comes in paperback, and is loads of fun.
The premise of the book is an everyday I.T. guy tracks an international computer criminal. I won't ruin the end for you...
One last thing, the story is true. This isn't fiction.
