The Ghost of Grania O'Malley

People on Clare Island say that the Big Hill is haunted by fearsome pirates who once terrorized Ireland's coasts. Jessie senses that the Hill possess a magic special enough to give her the strength to deal with a crippling disease. That magic takes physical shape when the ghost of pirate queen Grania O'Malley appears to Jessie with a mission--to save the Hill from a greedy prospector.
