When Jonathan and his family go camping on Magpie Island, they look forward to a fun, relaxing weekend. But their fun quickly vanishes when Jonathan, his sister, Abby, and their dog, Moose, find themselves in the middle of a natural disaster. A devastating earthquake has hit, destroying their camper, knocking out the only bridge to the mainland, and leaving Jonathan, Abby, and their dog with no food, water, or shelter. Alone in the woods, can Jonathan manage to keep calm and save Abby and Moose—and stay alive himself?
