A really interesting and well produced book, from the endpapers to the writing to the design and illustration. The book discusses an issue I've not yet seen in a picture book. The father is a 'shouter' and the child decides to reject this way of being and to not follow on with the family pattern of growing up to be a shouter too. It's not clear whether the 'shouter' is actively abusive in any other way, but this is perfect. The reader can extrapolate to apply the story to a number of forms of actual abuse within the family, or simply take it on face value as being about a man who can't keep his voice down. It's a great book to use for opening a discussion, and models the empowerment of a child of indeterminate age (well depicted through cats instead of humans).
I liked the way the book ends with a friendly re-connection between father and child, wherein the child retains her ground and her decision to be apart, but the relationship is restored on grounds that are acceptable and safe to the child. This is all very beautifully explained by means of the final illustration, about 5cm high. Well done Waechter and Port. (It's unclear which is the illustrator, as both are trained graphic artists living in Germany.) And well done Sally-Ann Spencer for your translation :-)
