In a small Alabama coal-mining town during the summer of 1931, nine-year-old Tess Moore sits on her back porch and watches a woman toss a baby into her family’s well without a word. This shocking act of violence sets in motion a chain of events that forces Tess and her older sister Virgie to look beyond their own door and learn the value of kindness and lending a helping hand. As Tess and Virgie try to solve the mystery of the well, an accident puts their seven-year-old brother’s life in danger, forcing the Moore family to come to a new understanding of the power of love and compassion.
