Hillbilly Elegy by J.D. Vance, a non-fiction memoir about growing up in a family that migrated from Appalachian Kentucky to industrial Ohio, but stayed in a culture of similar folks. The community had and has daunting problems with broken families, substance abuse, violence and joblessness, but the narrator escapes gradually from the grasp of this fate with the help of a thoroughly hillbilly maternal grandmother, Mapaw, who, as he says, is a gun-toting lunatic capable of holding off a Marine recruiter at the porch steps. He eventually joins the Marines, then goes to Ohio State, and eventually Yale Law School. He goes from describing how to dodge druggies and other peoples' love live gone wrong, to relating how to network to get the best law firm connections at Yale. He still wants to reach back and show young folks in his old home towns the way to a healthier, more productive life, hence the book. He teaches what I already knew; don't badmouth nobody's mama.
