In Niceville, a pleasant Southern town where evil lurks just beneath the surface, two back-to-back airplane crashes set off a spellbinding chain reaction of murder, inadvertent kidnapping, and double-dealing. Detective Nick Kavanaugh must balance his investigation into the accidents with family concerns and a long-buried mystery. He and his wife Kate, a family lawyer, have taken in Kate’s sister and her two children, escaping their abusive father Byron Deitz. The Kavanaughs are also caring for the orphaned Rainey Teague, who recently survived a strange kidnapping and has come back a very different child. Rainey was not the last person to vanish from a Niceville street; most recently, an administrator from Rainey’s school, and—even worse—Kate’s father, a local historian, have gone missing. Using her father’s files, Kate and Nick start to unearth their town’s bloodstained past, trying to discover the truth behind generations of disappearances. But a sinister someone—or something—stands in their way.
