<div>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.<br><br>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.<br><br>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?</div>
