More than anything else in the world, Adam wants a friend. One day, walking home from school, Adam picks up a conker and - almost as a joke - he makes a wish. He wishes for a friend. But the conker leads him to something quite different: a glittering glass bird hidden in the ferns. It's the most beautiful thing Adam's ever seen, and the most extraordinary - for the bird appears to live and breathe. Could it be that this wonderful creature has the power to make Adam's wish come true?
