She teaches her babies what food to eat, how to swing through trees, how to build a sleeping nest. Life is good... until one day a monstrous machine tears Orangutan's tree from the ground. The family have to leave the emerald forest - but where can they go to?

This powerful and moving picture book is set in tropical Sumatra, an island that has lost almost half its rainforest cover in recent years. The story graphically describes the reactions of an orangutan family to the destruction of their age-old home, but also shows how wildlife campaigners are bringing hope for the future.
