Happiness is a gift from the heart. And accompanying happiness is a smile. The children in this book learn from their father that love can transcend distance through a smile. They are encouraged to be happy and helpful while he is away on assignment - that's their work -- and he will do the same. Separation from a parent who is deployed or soon to be deployed in the military is a hard situation for many young children to handle. This is the author's fourth book on the subject, each one designed to help a child overcome the sadness that may occur. All in rhyme and beautifully illustrated.
