I survived the Battle of Gettysburg, 1863

It's 1863, and Thomas and his little sister, Birdie, have fled the farm where they were born and raised as slaves. Following the North Star, looking for freedom, they soon cross paths with a Union soldier. Everything changes: Corporal Henry Green brings Thomas and Birdie back to his regiment, and suddenly it feels like they've found a new home. Best of all, they don't have to find their way north alone -- they're marching with the army. But then orders come through: the men are called to battle in Pennsylvania. Thomas has made it so far ... but does he have what it takes to survive Gettysburg?.
