The action of WWII comes alive through American soldier Joe's letters home to his younger brother, Charlie!When Charlie's brother, Joe, is called up to fight in World War II, he promises to write letters to ten-year-old Charlie as often as he can. It won't make up for not being there to help Charlie out with the neighborhood bullies, but it's all Joe can do. Life is tough for a soldier, and Joe tells Charlie all about it, from long hikes in endless rain and mud to the stray dog his company adopts. But when Joe is sent on a secret mission with the one soldier he can't stand, he will have to face risks that place their mission -- and their lives -- in grave danger. Charlie knew his brother was strong, but he will discover that Joe is more of a hero than he lets on. Will Joe's letters give Charlie the strength to stand up for himself and be brave, too?.
