You are offered the newest author’s revision of the novel, which the writer considers the final version. Only the young and strong survived on the mountains of weapons left behind by a civilization. In this new world, everyone is equal. Everyone paid for the right to be here with their own memory—by taking away their past, making them forget their loved ones and friends, seizing them with a thirst for senseless aggression. But anyone who wants to remember more than others must be the most ruthless killer and is simply required to shoot first. Such is the law of survival in this world—the Law of the Frontier.
