Book excerpt: Stewartville. A town living in the shadow of the prisons that drive its economy. Haunted by the ghosts of its past. Cursed by the dark secrets hidden beneath. A town so entwined with the prisons waiting outside the city limits that it's impossible to imagine one without the other, or to ever imagine escaping either. When a teenage boy digs into the history of the town, he discovers a tunnel system beneath Stewartville, passageways filled with dark secrets. Secrets leading not to freedom, but to unrelenting terror. Stewartville. Where the convicts aren't the only prisoners.
