Saved from mercenary Nomads by Sunny, M.K. is taken to Quinn's walled compound, The Fort. A seemingly average teenage boy, M.K. is anything but. Lurking inside him is a dark energy that is only unleashed when his skin is cut. No longer himself, he becomes an unstoppable force with heightened and brutally lethal martial arts skills. Haunted by his murderous capacity, M.K. tries to keep his unwanted powers a secret. But Sunny senses something different about the teen, and it isn't long before M.K. is forced to tell the Clipper the truth. At the same time, the duo forms a bond when the boy saves Sunny's life. Sunny recognizes, however dimly, the faraway place M.K. calls home. And M.K. knows that if Sunny can train him to harness the darkness within, there is hope they can both find their way home.
