On a steamy spring morning, Dusty Parker—part-time pastor, part-time search-and-rescue team member, and full-time administrator of a school for troubled boys—joins the search for a missing teenage girl. He partners with volunteer and inner-city school teacher Grace Sinclair, and what they find bonds them in ways neither could have expected.

As they begin to build their lives together, a visitor from the past causes Dusty and Grace to further open their hearts. But a threat is looming on their seemingly perfect lives and in one terrifying night, everything changes.
