Ride along with 13-year-old eco-warrior Julie Leeds and her futuristic car Jett as they race to the Florida Keys to help save the endangered coral reefs. While spending the summer in Key West, also known as the "Island of Bones," Julie and Jett discover why the coral reefs are dying. But not everyone wants the reefs to be saved, and Julie soon faces a series of threats, a spy ring, high-speed chases, and deep-sea kidnap attempts. From close encounters with deadly sharks, shipwrecks, and buried treasure, to menacing messages and ruthless treasure hunters, Julie's summer is a harrowing thrill ride that leads her to an infamous fort, where she learns of her own family's connection to a long-forgotten secret. An environmental glossary and shell guide included.
