Sisters Rose and Lily Martin were inseparable when they were kids. As adults, they've been estranged for years, until circumstances force them to come together to protect Rose's daughter. Ten-year-old Antoinette has a severe form of autism that requires constant care and attention. She has never spoken a word, but she has a powerful gift that others would give anything to harness: she can heal things with her touch. She brings wilted flowers back to life, makes a neighbor's tremors disappear, and changes the normal course of nature on the Kentucky flower farm where she and her mother live. Antoinette's gift, though, puts her own life in danger, as each healing comes with an increasingly deadly price. As Rose-the center of her daughter's life-struggles with her own failing health, and Lily confronts her anguished past, they, and the men who love them, come to realize the sacrifices that must be made to keep this very special child safe.
