This I Know

Grace Carter has the Knowing. It offers glimpses of people's pasts and futures, and allows Grace to talk to Isaac, her twin brother who died at birth. To Aunt Pearl, the Knowing is a family gift; to Grace's strict Evangelical pastor father, it's witchcraft. Her sisters Hope, Joy, and Chastity enjoy a normal life. It's Grace's friendships that keeps her afloat: Lyle, a gentle, homeless man, and Lola, a free-spirited girl at school. When a young girl goes missing, and Grace's mother lapses into deep depression after bringing home a new baby, Grace must find the courage to stand apart, and make herself heard.
