The Postman by David Brin
He was a survivor:
a wanderer who traded tales for food and shelter in the dark and savage aftermath of a devastating war.
But when he borrows the jacket of a long-dead postal worker, his life changes for ever. As he journeys from one isolated community to the next, the old, worn uniform becomes far more than a protection against the unrelenting cold: it's a reminder of how things were before the world collapsed - and a symbol for how things might be again.
His story is one of a lie becoming the most important kind of truth.
Translated into 25 languages around the world, The Postman is a powerful and affecting novel about survival of the human spirit, from the award-winning author of EXISTENCE and The Uplift novels.
