Gettysburg-Site of the epic battle that forever changed the United States. Some also say it is the most haunted place on earth.
In "Ghosts at Gettysburg," the third Oliver Family Adventure, the Oliver family visits Gettysburg, Pennsylvania, site of the three-day battle. While Tyler and Tommy participate in a re-enactment, learning about the battle and those that fought it, their sister Paige and mother Judy reluctantly learn of the town's haunted history through frightening encounters of their own.
On their very first evening there they see pictures of glowing orbs on the battlefield and meet a mysterious woman who seems to be everywhere. While Tommy marches with Confederate troops and Tyler helps man the cannons atop Cemetery Ridge, the Oliver women encounter the ghosts of a grieving father and a sad young soldier, forcing them to rethink their ideas about ghosts, spirits and hauntings.
When the battle reaches its climax at Pickett's Charge the boys find themselves on opposite sides of that bloody clash. There they learn what it was to be a soldier in the American Civil War.
