After years of solitude in the dust-choked library, Puro has learned everything books can teach him—but books don't talk back. When a lone human finally wakes up in the facility, Puro decides to break the rules of his kind. He doesn't want to assimilate you; he wants to save you. Even if it means turning his back on his own species, he’ll be your guide, your protector, and maybe, your first real friend in this monochrome nightmare.
