Cuckoo's Egg - by Cliff Stoll

About 10 years ago a saw a special on PBS about Cliff Stoll and how he traced an international hacker after finding a 75cent discrepancy in the Lawrence Berkley computer systems - just an amazing story. This is a true geek/hacker book for those technically inclined (even though there is little technology discussed). Highly recommended enjoyable read - recharges the batteries.
