It's Lulu's birthday soon, but it's her brother Billy's birthday first. As cards arrive for Billy and not her, and her parents plan Billy's birthday party, Lulu becomes more and more cross. To spoil the fun, she hides the special ball that Billy's friend has given him. Billy is very upset when he can't find it, so he and his friends have to fly his kite instead. But then Lulu can't find her favourite yo-yo and suddenly she realises how Billy must feel.

A story about childhood jealousy and sibling rivalry, this charming book provides food for thought and discussion with young readers. Written by an author with extensive experience of children and children's books as both teacher and publisher, it is illustrated with great verve by an established artist.
