"Ghosts" serves as a guidebook to haunted sites in Pennsylvania and Western New York. The author visited these places himself to take photos and suck up their scary atmosphere. The tales he tells come from local folklore, friends' testimonies, and internet research. Spooky highlights include the Shadow People of the Hinsdale House, the headless ghost of Old Fort Niagara, and the spirit children seen at the Halton Baby Cemetery. William P. Robertson is quite familiar with the eerie, having penned such short story collections as "Dark Haunted Day," "Lurking in Pennsylvania," and "Fear Is Forever."
