Leilani O'Brien is relieved when her husband and four-year-old daughter, Holly, are killed in a car accident. Glad to be freed from a failing marriage and the demands of motherhood-and horrified by these feelings-she settles on suicide as her only option. Across town, college senior Delphi begins to 'see' Holly-a persistent image begging for help. Skeptical and scared, Delphi eventually acquiesces to both her psychic gifts and Holly's pleas, until she stumbles into an unthinkable betrayal and finds herself searching for two missing mothers, Holly's and her own.
