Agents Eckis and Sheen swore an oath to protect the civilian population from the eminent danger of the rogue black market clones known as "Dupes" that can suddenly "pop" without any advance warning-which means any passerby on the street or subway could possibly become an unhinged spree killer on a moment's notice. In return for their service, however, the public has dubbed Eckis, Sheen, and their fellow agents the "Skin Police"-an insult handed back by a populace unwilling to sacrifice their own civil rights for the agents' unprecedented duties in light of the Dupe threat. But what if these illegally manufactured clones doppelgangers weren't as deadly as initially believed? What if they could be saved? And, as the underground resistance movement supporting them grows, what if their leader proved to be someone uncomfortably familiar to the Skin Police?
