Angel Song tells the story of New York designer Ann Fletcher who, on a visit home to South Carolina, experiences a tragic loss. In her grief, Ann begins to sense the presence of angels – and wonders whether this means that she is losing touch with reality. She is befriended by 12-year-old Keith, a boy who has Down syndrome. Ann is startled to hear Keith describe the angels he sees every day. Ann doubts Keith’s claim that angels surround her, but wonders why she hears music no one else but the two of them can hear. She also becomes aware that something mystical seems to be conspiring to keep her in her childhood home, next door to Keith. Ann’s life is transformed when she joins a new community, discovers a long-lost letter, and recognizes the love and presence of God.
