Eleven-year-old Grace Carter has a talent for hiding things. She's had plenty of practice, burying thoughts and feelings that might anger her strict Evangelical pastor father, and concealing the deep intuition she carries inside. The Knowing, as Grace calls it, offers glimpses of people's pasts and futures. It enables her to see into the depth of her mother's sadness, and even allows Grace to talk to Isaac, her twin brother who died at birth. To her wise, loving Aunt Pearl, the Knowing is a family gift; to her daddy, it's close to witchcraft.

Grace can't see into someone's thoughts without their permission. But it doesn't take her special talent to know that her small community is harboring its share of secrets. A young girl has gone missing. Within Grace's own family too, the cracks are widening, as her sisters Hope, Joy, and Chastity enjoy the normal life that eludes Grace. It's Grace's kinship with other outsiders that keeps her afloat—Lyle, a gentle, homeless man, and Lola, a free-spirited new girl at school. But when her mother lapses into deep depression after bringing home a new baby, Grace will face a life-changing choice—ignore her gift and become the obedient daughter her father demands, or find the courage to make herself heard, even if it means standing apart . . .
