When Miranda begins writing in her new diary, she is an average teenage girl, living in an average Pennsylvania town and the diary reflects her typical adolescent self-absorption. However, an asteroid hits the moon, and the weather and life around her changes suddenly and not for the better. Mass hysteria is followed by the slowly dawning realization that the normal life that she and her family once knew is gone and may never return. Miranda’s diary reveals the growing anxiety and fear within her family as things deteriorate and there is scarcely power,water or food. Her family survives illnesses and injuries, and the death of close friends, but are cut off from any knowledge of what is happening beyond their town. "The sense of doom in this fast-paced, speculative novel is overwhelming, but so, too, is the humanity of its characters and the will to survive." (CCBC Review)
