Jared, Sadie and their new Mackinac Island friends Eric and Becky find themselves turning into detectives as strange events occur all over the island. Native American art and artifacts are vanishing from gift shops and art galleries. At the Governors Conference, Dr. Royalton is demanding that Great Lakes water be diverted for use by states in the southwest and then he disappears! As the four teenagers explore the island and its historical sites looking for clues, they find themselves facing an evil Gi-bi who locks them in a dungeon. Will they get out in time to save Dr. Royalton? Will they discover who stole the copper turtle and other art from the island stores? Eric and Becky s cousin Luke keeps interfering in their investigation. Is he involved or just the jerk Jared thinks he is? How is all this connected or is there more than one mystery to solve?
