Isabel is good at noticing beautiful things around her. But when her family can no longer afford their house and move to a tower block on the far side of the city, she starts to feel invisible. Then something happens: Isabel suddenly starts to notice other invisible people. She sees what they are interested in and starts to help them fix things up. Gradually other people join in. The neighbourhood is transformed from a cold, sad and lonely place to a vibrant and colourful community. Isabel has achieved something special: she has made a difference.
