With Dad's cancer, everything suddenly changes for Leo's family. He comes home from the hospital without hair, thin and tired, and gets annoyed when Leo and Lisa argue. Leo doesn't really understand what cancer is. Even when the doctor explains it to him, many questions remain: Is it his fault, can cancer be cured by being loving, will Dad die? The book helps families in particularly difficult situations and provides sick fathers and their children with helpful answers. Sometimes Leo is so angry that he imagines cancer standing in the goal and he shoots it away with a soccer ball. He doesn't want to be a "poor boy"! He wants to play carefree with his friend Malte and go out for ice cream with Dad again. Luckily, the grandparents are there with their honesty and a comforting portion of chocolate pudding for Leo. This sensitively designed picture book.
