Twenty-year-old Isabella has spent the past two year traveling across the country; not in the spirit of adventure, not in search of purpose, but for the sake of her mission. There's a voice that has led her from home and takes her to specific places. Her dad calls the voice "God," her best friend calls it her conscience, and her younger brother calls it schizophrenia. Whatever it is, the voice brings Isabella to people and allows her to help them, until the day Isabella is faced with something new, something evil.
