Seeking the Cross in Dracula's Castle

A group of young people called the Find It Club go to Cruden Bay, Scotland to look for an ancient artifact hidden in the castle that inspired the story of Dracula. Broc, Chloe, their mother, grandparents, aunt and uncle and best friends stomp around the grounds and tunnels of Slains Castle looking for a piece of the cross upon which Jesus the Christ was crucified. It was believed by the locals that the cross had healing power. Cruden Bay is turned upside down with new religious fervor. Broc and Chloe's mother and best friends end up in jail in Royal Dornoch. It takes a miracle to get them out. Various religious powers want to possess the cross for their own purposes and power.
