Book excerpt: Flynn hates the outdoors. Always has. He barely pays attention in his Outdoor Ed class. He has no interest in doing a book report on Lost in the Barrens. He doesn’t understand why anybody would want to go hiking or camping. But when he gets lost in the wilderness behind his parents’ friends’ house, it’s surprising what he remembers—insulate your clothes with leaves, eat snow to stay hydrated, build a shelter, eat lichen—and how hopelessly inept he is at survival techniques.
