As an independent consultant, she now uses her specialized skills to train law enforcement and private organizations in crisis resolution. But when one of her closest childhood friends mysteriously disappears, and the woman's devastated parents beg for her help, Sloane takes the case—even though her ex-lover Derek Parker is the FBI agent in charge.
