Sister Agatha is an extern nun in the cloistered order at the Our Lady of Hope Monastery near a small New Mexican desert town. As an extern, Sister Agatha is the link between her cloistered sisters and the outside world. Usually this means running errands in the monastery's slowly dying automobile (dubbed the Anti-Chrystler) or their motorcycle with Pax, the order's German Shepard, in the side car. Sometimes her duties involve a bit more--like when Father Mahoney's eight-year-old niece goes missing in the middle of the night. Now it's up to Sister Agatha to find the girl…and to find out whether the young Natalie was telling the truth when she claimed to have a guardian angel--or if someone in the community has something far more sinister in store….
