The one thing the little boy seems to know is that 'Some time ago we said goodbye to Mummy.' He is very sad, but doesn't know quite why. He looks for his mummy everywhere, thinking she has gone away, and then he gets angry and frightened, because it begins to dawn upon him that she might not be coming back. Was it his fault? Did he do something naughty that caused her to leave? When he finally asks his dad when mum is coming back, dad realises what the child is going through and explains: 'you cannot come back once you have died because your body doesn't work any more.' Dad makes it clear that he and the little boy and his older sister are still very much a family and that it was nothing the child did that made his mummy go away. They are able to share memories and happy times and sometimes to cry together, and they all help with the chores around the house. There are moments of humour, but these in no way detract from the essential theme of the story; in fact they add to the realism of the whole. The pictures are a moving combination of child-like naivity and large expanses of white space, indicating grief. This is a beautiful book, full of warmth and family love and with hope at the end.
