It's Walter's birthday, and he has big plans for his party. His best friend, Iris, is making a surprise present for him, and even Walter's horse, Rain, is excited. But when the big day finally arrives, something totally unexpected happens. Will the sudden change in plans ruin everything, or turn it into the best birthday ever? Christine Davenier's charmingly expressive illustrations show a full range of childhood emotions.
