Every year a scout unit goes to the uninhabited island of Falstaff off the coast of Canada, where they spend weekends in the wild, learn how to make fires, catch fish, and navigate the area. It’s a tradition—there are no surprises—and each generation remembers these trips with joy and nostalgia. Only this time everything will be different. A strange stranger approaches the scouts’ camp—a ridiculously skinny, horribly pale, and monstrously hungry man. They’ll face something far worse than any ghost from a campfire tale. They’ll face a carrier of real nightmare created in biogenetic laboratories. And now the scoutmaster Tim Riggs and his charges will have to fight the elements, the infected, and even their own companions—and the price of survival will be unbelievably high.
