The book: One day, a new student named Sarah comes to White's school. She is dark-skinned. Very dark-skinned. She does not look like the other girls in the class. "Like day and night!", "Milk one, cocoa the other!", "Light and darkness," some students comment on the difference. How did a rainbow and some tempera paint manage to convince the students that children, whether they are white or dark-skinned, are always sweet like white and dark chocolate? The series: In order for children to ensure a healthy social life built on effective relationships, they must cultivate empathy, which is the ability to put themselves in someone else's shoes, to understand and feel things in the same way another person experiences them. This need is fulfilled by the illustrated books of this series, which promote emotional intelligence. With the approach proposed for parents and educators, they attempt to introduce children to seeing the world through someone else's eyes, after first learning to recognize and manage their own emotions.
