In quiet Willow Creek, Pennsylvania, divorced history teacher Jack Harlan receives a midnight call from Emily Voss, his high-school sweetheart who vanished twenty years earlier. Drawn into her dangerous quest to settle an old family debt, Jack retrieves incriminating documents from a Pittsburgh bank and faces down threats at their old meeting spot by the creek. With humor, loyalty, and reluctant courage, he helps her escape her past—proving some promises, even decades old, are worth keeping in the dark hours when history calls again.
