Kevin never smiles at school, but he is different at home. He jumps up and down when his favorite football team scores a touchdown, and screams "CANNONBALL!" when he jumps into the swimming pool. But at school he feels that he isn't 'okay.' Other kids in his class are much quicker at putting their hands up and answering the teacher's questions, and Kevin feels that he will never catch up. One day, his reading teacher asks him to help out with the school store, and Kevin slowly begins to realise that he had really been 'a okay' all along.

Through providing an insight into Kevin's thoughts, feelings and coping strategies, this picture book for ages 5-8 is a source of support for children who, like Kevin, find school difficult and feel that they are 'behind' their peers. The book, which draws on the author's experiences as the principal of an elementary school, is also the perfect springboard for discussion around difficulties at school, academic ability, self-esteem, confidence and recognising strengths.
