He never talks and never smiles and doesn't like sweets - not even lemon sherbets, which are my favourite! But the truth is, Ahmet really isn't very strange at all. He's a refugee who's run away from a war. A real one. With bombs and fires and bullies that hurt people. And the more I find out about him, the more I want to be his friend.

And about 65 kilometres out to sea, one last remote outcrop of islands and sea stacks, with the highest sea cliffs anywhere in the UK - St Kilda - the islands at the edge of the world.
