The Little Drummer Girl of Gettytsburg

Abigail died a hero on the blood-soaked fields of Gettysburg, but was denied a soldier's grave.

Bert, Emma, Ronnie, and Derek, just a bunch of kids on vacation, risk all to help her get the hero's burial she deserves before time runs out.
Join them on this hazardous quest.
