Hannah Diamond loves to write letters. When her best friend Aggie moves away, they vow to be bet pen pals forever. Hannah keeps her side of the bargain and writes long letters regularly, but Aggie never writes back. In her despair, she writes to a boy in another state whose name she drew out of a pen-pal hat at school, and to President Franklin Roosevelt. To her surprise, both of them become good friends with her.
This tender-hearted, but never sappy book is told entirely through the letters that Hannah sends and receives. In addition to the those mentioned above, there are exchanges with Hannah's grandmother, her Aunt Becky, Eleanor Roosevelt, President Roosevelt's secretary, and a small handful of others.
