Watership Down by Richard Adams

Chronicles the adventures of a group of rabbits searching for a safe place to establish a new warren where they can live in peace.

Set in England's Downs, a once idyllic rural landscape, this stirring tale of adventure, courage and survival follows a band of very special creatures on their flight from the intrusion of man and the certain destruction of their home. Led by a stouthearted pair of friends, they journey forth from their native Sandleford Warren through the harrowing trials posed by predators and adversaries, to a mysterious promised land and a more perfect society.
