Kensuke's Kingdom

When Michael is washed up on an island in the Pacific after falling from his parent's yacht, the Peggy Sue, he struggles to survive on his own. But he soon realises there is someone close by, someone who is watching over him and helping him to stay alive. Following a close-run battle between life and death after being stung by a poisonous jelly fish, the mysterious someone--Kensuke--allows Michael into his world and they become friends, teaching and learning from each other, until the day of separation becomes inevitable.
Morpurgo here spins a yarn which gently captures the adventurous elements one would expect from a desert-island tale, but the real strength lies in the poignant and subtle observations of friendship, trust and, ultimately, humanity.
