Chucky doesn’t know why he feels such a strong connection with the entity that they encounter on the hilltop trail, but he wishes he didn’t feel that way! Luckily, their ghost-friend, Corporal Jared Scott, is willing to work with them to find out what the ghost-horse is searching for. When he meets the mare, the corporal realizes it once belonged to a fellow in his unit in the Michigan cavalry. Little do the boys know that working with Corporal Jared Scott to help the horse find peace will uncover a sad truth and lead to the Soldier’s National Cemetery in Gettysburg.
