Kensuke’s Kingdom by Michael Morpurgo

Michael is hungry, lonely and scared when he is washed up on a seemingly deserted island. He soon discovers another inhabitant - Kensuke, a former Japanese soldier - who, although initially unfriendly, provides Michael with food and water.

Gradually, a strong bond develops between the two castaways. This is a beautifully written tale of an exceptional friendship which survives beyond the boundaries of culture and language.
