When Christina and her friends head to Savannah, GA for the National Camporee in celebration of the Girl Scouts' 100th Anniversary, Christina reassures them that on this trip, there will be no funny business and no mysteries. But as they begin exploring the historic city they stumble upon creepy clues that lead them to River Street, a spooky cemetery, on a ghost tour, and even to Juliette Gordon Low's home. With just a few days before the Camporee begins, they find themselves in the middle of a real mystery that is going to need all of the Scouting skills they have, as well as their friendship, to solve!
