Matt Cahill has an unusual gift: he can see the corruption in people’s souls, making the afflicted appear as walking corpses to his eyes. This macabre ability has set him on a one-man crusade to eradicate these servants of an ancient and powerful evil, embodied by the aptly named “Mr. Dark.” On his way through the small town of Breckenridge, Minnesota, Matt sees the unmistakable signs of corruption in the chief of police and numerous cops. The evil that has consumed them now terrorizes innocents and allows drug and sex trafficking to run rampant. Just as Matt confronts the enslaved cops, a gun-toting teen appears, looking to make Matt pay for murdering her brother. Of course, Matt did kill her brother—he was another corrupted soul who’d been planning a bombing. But how can Matt convince Elena of the truth without any proof? Trapped between Mr. Dark’s forces and a girl hell-bent on revenge, Matt faces an impossible choice: remove Elena—permanently—or let her kill him and doom the town.
