Texas Ranger Darren Mathews isn't sure he's been a good cop, but believes he's got a shot at being a good man--if he manages to dodge the potential indictment hanging over his head and if he, from here on out, pledges allegiance to the truth. It's a virtue the country appears to have wholly lost its grip on, but one Darren sees as his salvation. He is in the midst of remaking his life with the woman he loves, hoping for the peace of country living at his beloved farmhouse, when he is visited by someone who couldn't hold the truth on her tongue if it was dipped in sugar, a woman who's always been bent of tearing his life apart. His mother. Armed with a tall tale about a missing Black college student, Sera (whose white sorority sisters insist she isn't missing at all). Darren must decide if his can trust his mother is telling the truth--and what her ulterior motive may be, and what if that motive has to do with a grand jury deciding his fate.

Darren gets his hooks into the investigation, along the way discovering things about Sera's family and her hometown that are odd at best, vaguely sinister at worst. Hamstrung by local law enforcement and the Texas Rangers who likewise doubt the account of a missing girl, if Darren wants answers, he'll need help from the person whom he swore to never trust again--his mother.

In this emotionally stirring conclusion to the singular Highway 59 series, set three years after the events of Heaven, My Home, Darren reckons with his life's purpose as he's forced to choose between his own peace and the higher call to do good.
