the Cursed Land and Haunted House: Book 3 in Liana Dylan stories

Liana and Dylan have experience with ghosts. In book one of the series, Ghosts in the Wings, they managed a haunted apartment house. They discovered that they see ghosts even if others do not. They help most of the ghosts leave earth life for the great beyond. In book two of the series, Ghosts of the Drive, they take a driving vacation so that Dylan can get a rest from being haunted. He doesn't get a break. The Cursed Land and Haunted House is book three of the series. Liana and Dylan are taking on a project. They purchased a house known in the rural community for being haunted by a family of ghosts. The house itself stands on fifty acres of land that is said to have a curse. Nothing has grown on the land in one hundred years. They have become confident in their ability to help ghosts on their journey to a better life. The question is: do they have what it takes to overcome a curse, while at the same time helping ghosts that don't want to move on?
