Maeve Harper, a seventeen year old girl, finds herself surrounded by the destruction of the world. She's afraid she's the only one left alive. She sets out cross country from her home in Oklahoma, only accompanied by her Great Dane, Rex, and essentials in her backpack. She thought she was alone, until one night she stumbled upon Ashton Scott, a boy who had graduated from her high school. She was apprehensive at first but soon found herself falling for him as they searched for the answer behind the madness. They must take a stand.
