She has no idea who or where she is. Or why she's dead. The only clue to her identity hangs around her neck: a single rusted key. This is how she and the others receive their names—from whatever belongings they had when they fell out of their graves. Under is a place of dirt and secrets, and Key is determined to discover the truth of her past in order to escape it. She needs help, but who can she trust? Ribbon seems content in Under, uninterested in finding answers. Doll’s silence hints at deep sorrow, which could be why she doesn't utter a word. There's Smoke, the boy with a fierceness that rivals even the living, and Journal, who stays apart from everyone else. Key's instincts tell her there is something remarkable about each of them, even if she can't remember why. Then the murders start. Bodies that are burned to a crisp. And after being burned, the dead stay dead. Key is running out of time to discover who she was—and what secret someone is willing to kill to keep hidden—before she loses her life for good.
