Man-on-Fire isn’t just any kid—he’s the one who knows the iron river better than anyone. Trains thunder past his neighborhood, carrying secrets and danger, but when a hobo’s murder shakes everything, Man-on-Fire and his friends face a threat bigger than their wildest adventures. Can they prove their innocence before the stinking cop’s lies derail their lives?
