Mercy is hard in a place like this . . . It's February 1976, and Odessa, Texas, stands on the cusp of the next great oil boom. While the town's men embrace the coming prosperity, its women intimately know and fear the violence that always seems to follow. In the early hours of the morning after Valentine's Day, fourteen-year-old Gloria RamÔirez appears on the front porch of Mary Rose Whitehead's ranch house, broken and barely alive. The teenager had been viciously attacked in a nearby oil field—an act of brutality that is tried in the churches and barrooms of Odessa before it can reach a court of law. When justice is evasive, the stage is set for a showdown with potentially devastating consequences.
