Bloodline's Brutal Dawn

When civilization collapses overnight, former Internal Affairs investigator Caleb Cross discovers that the cruelty needed to survive is not a skill he learned—it is an inheritance. As he claws his way through the ruins of Meridia to establish the first savage code of order, buried secrets about his father's true role in a pre-Fall corruption scandal surface, forcing Caleb to confront a terrifying truth: the capacity for monstrous acts has always flowed silently through his veins, waiting for the law to die so it could finally be born.
