The Ghost of Jessica Majors: Just Plain 11

Ages 8-12. Jessica Majors is 11 years old — or 154 if you include all the years she's been dead. After Jessica's mysterious death in 1875, she returns as a ghost in 2017 to find a world much different than the one she left behind. With the help of her 11-year-old descendent Luke, and his soon-to-be step-sister Dahlia, she must confront the supernatural forces threatening the quaint town of Curiosity, Maine.
