Amir Zebib is a nine year old boy. He was born in Lebanon and lives in Belgium. He started writing when he was eight because he was inspired by his mother who is an author. He wrote this book for younger children to help them manage their grumpy moods. Amir understands how it feels when a child is upset, and he has learned how to help himself feel better, as well as how to ask others for help. He wrote this book to help other children, too. This is his first book.
