Then one day Gran brings home a child to stay with the family. Iris--silent, hollow-eyed, skittish, and feral--does not behave like a normal girl. Still, Violet is thrilled to have a new playmate. She and Eric invite Iris to join their Monster Club, where they dream up ways to defeat all manner of monsters. Before long, Iris begins to come out of her shell. She and Vi and Eric do everything together: ride their bicycles, go to the drive-in, meet at their clubhouse in secret to hunt monsters. Because, as Vi explains, monsters are everywhere. 2019: Lizzy Shelley, the host of the popular podcast Monsters Among Us , is traveling to Vermont, where a young girl has been abducted, and a monster sighting has the town in an uproar.
