19-year-old Night Vale pawn shop owner Jackie Fierro is given a paper marked 'KING CITY' by a mysterious man. She can't seem to get the paper to leave her hand, and no one who meets this man can remember him, but she is determined to uncover the mystery before she herself unravels. Across town, Diane Crayton's son, Josh, is moody and also a shape shifter. Lately Diane's started to see her son's father everywhere, looking the same as the day he left years earlier. Josh, looking different every time Diane sees him, shows more and more interest in his estranged father, leading to a disaster she can see coming, even as she is helpless to prevent it. Diane's search to reconnect with her son and Jackie's search for her former routine life collide as they find themselves coming back to two words: 'King City'. It is this that holds the key to both their mysteries - if they can ever find it.
