Running Wild - Michael Morpurgo.

Running wild is a book about a boy named Will who's dad dies in Iraq. After the loss of his dad his mum and him are very sad and finding it hard to cope so their grandparents buy them a holiday in Indonesia to clear their minds and let them relax.
The trip was all going to plan until one morning when will is having an elephant ride on an elephant named Oona, a tsunami comes in. The elephant sensed it coming early and stamped with William on his back, but unfortunately wills mother is not so lucky because she was in a hotel near the beach.
The elephant takes Will into the rain forest for safety, but it is not all safe in the Rainforest and there are many adventures. 
I would rate it 8/10
