A prequel to the modern-day classic The City of Ember.While visiting the small town of Yonwood, North Carolina, eleven-year-old Nickie makes some decisions about how to identify both good and evil when she witnesses the townspeople's reactions to the apocalyptic visions of one of their neighbors. Nickie will grow up to be one of the first citizens of the city of Ember. But for now, she's an eleven-year-old girl whose father was sent away on some mysterious government project. So when the opportunity to move presents itself, Nickie seizes it. But her new town of Yonwood, North Carolina, isn't what she'd anticipated. It's a place full of suspicion and mistrust, where one person's visions of fire and destruction have turned the town's citizens against each other. Nickie explores the oddities around her-her great-grandfather's peculiar journals, a reclusive neighbor who studies the heavens, a strange boy who is fascinated with snakes-all while keeping an eye out for ways to help the world. Or is it already too late to avoid a devastating war?
