1The Grateful Tree is the third book released in The Book of Mac Series. The purpose of this book, was to create positive and impactful conversations between parents and children. The main character, Mac, completes a school project where he lists each of the things he is most grateful for. It is important for us all to reflect on what we have and show gratitude for it. We hope this book offers this to anyone who reads it. The first dollar to each book sold will go to No Kid Hungry, which helps fight childhood hunger.
