A high school honor student loses the girl he swore to protect. Two days later, seventeen people are dead—and he doesn’t run. The judge gives him a suspended death sentence. Then he’s shipped to a place that isn’t a prison at all: a death-row coliseum, where monsters rule by cell number, and every day has one hour when the guards “look away.” Welcome to Cell 502. If he survives, he won’t be a prisoner. He’ll be the one holding the throne.
