For fans of Gary Paulsen's Hatchet, a story of two girls who must rely on their wits to stay alive when they become trapped in the snow. When Erin goes looking for her babysitter, who has disappeared, she persuades Tiffany, her new science partner, to do a project on animal tracks, figuring the project will give her an excuse to search the woods for Amy. While the two girls are in the woods, a sudden spring blizzard strikes--and they know no one will start to look for them for the next three days. A page-turning adventure of wilderness survival
