David Brin's "The Postman", (Yes, made into a Kevin Cosner movie in the 90's!) is a tale of post nuke-u-lear war. The book tells of what happens after the US is destroyed, and how one man finds his destiny, and a way to survive in this difficult time. He helps bring the spirit of our country back alive, despite being a stranger to the communities he visits.
It is a good introduction to the concept of post nuke-u-lear war. Very scary, yet helps you to remember WW III may be coming sometime soon.
From the Inside Flap
This is the story of a lie that became the most powerful kind of truth. A timeless novel as urgently compelling as War Day or Alas, Babylon, David Brin's The Postman is the dramatically moving saga of a man who rekindled the spirit of America through the power of a dream, from a modern master of science fiction.
He was a survivor--a wanderer who traded tales for food and shelter in the dark and savage aftermath of a devastating war. Fate touches him one chill winter's day when he borrows the jacket of a long-dead postal worker to protect himself from the cold. The old, worn uniform still has power as a symbol of hope, and with it he begins to weave his greatest tale, of a nation on the road to recovery.
