The Legend of Mother Sarah: City of the Angels #4

Some people are born under a lucky star. Among the battered and abused orphan girls serving Mother Teres, Satoko is one of the lucky ones. The tall, strong woman waiting outside the church doors is Sarah, her mother, rewarded at last after ten years of searching for her long-lost daughter. But the joy of reunion is brief. Ten years have scarred both mother and daughter, and before they can even begin to heal the wounds, the armored forces of Mother Earth open their final assault on the refugee-clogged town, and the Church of Mother Teres is in the way!
