Etta is worried about her brother, Jamie. The doctors can find nothing wrong with him, but he is getting weaker by the day. At breakfast one morning, he seems to have lost it completely: In a voice as pale as his face, he said, 'I think I can see a ghost.' However, when they all turn to look, sure enough, materialising on the window seat is a girl about Etta's age, wearing a beautiful Victorian wedding dress. Etta has to get off to school, she has no time for this, but she is about to discover that time has a whole new significance. She and her ghost companion have no choice but to work out what is going on before Jamie is lost for ever.
