Moss's work spans the many ages of a child. She started her first career making picture books. Amelia's Notebook was her first deviation from that format. This book is the format of a journal or diary and is penned in a black and white composition notebook. Moss herself says that she loves this format that she stumbled upon because it allows her to explore the world through a child's eyes. In fact, she says, "The things that happened to Amelia really happened to me--from the fire in the school to the marshmallows on the ceiling ... though the names have been changed because my sister is mad enough at me already!"
