Marion 'Doc' Ford is sure he's beyond the point of being surprised by his old friend Tomlinson's madcap adventures. But he's stunned anew when avowed bachelor Tomlinson reveals that as a younger man he'd fathered multiple children via sperm bank donations. Thanks to ancestry and DNA websites, Tomlinson's now-grown offspring have tracked him down, seeking answers about their roots. But one of them might have something far more nefarious than a family reunion in mind, and when strange things start happening in Tomlinson's presence, it will be up to Doc to prevent his friend's past sins from turning into deadly present-day dangers.
